GPS Antenna Types, RTK vs GNSS, Signal Boost & Car Mount Tips

Aug 10,2025

Ever wonder how your phone or car knows your location? The answer partly lies in the GPS antenna. This small but crucial component receives signals from satellites, enabling devices to pinpoint their position on Earth. From vehicles to smartphones, GPS antennas are everywhere, quietly doing the heavy lifting for navigation and timing. In this complete guide, we’ll explain what a GPS antenna is used for, the different types of GPS antennas (including active vs passive and high-precision RTK antennas), how to achieve the best signal reception (with tips on boosting GPS signals), and the differences between GPS and GNSS antennas. Whether you’re troubleshooting a weak signal in your car or curious about advanced GNSS antennas, read on for answers.

What Is a GPS Antenna and What Is It Used For?

A GPS antenna is a specialized radio antenna designed to receive signals from GPS satellites. It does not transmit; instead, it listens for the faint radio signals (at about 1.575 GHz for GPS) sent by satellites orbiting Earth. These signals carry timing and position data. The GPS antenna feeds those signals to a GPS receiver, which then calculates location, speed, and time. In essence, the GPS antenna is like the “ear” listening for satellite signals, while the receiver is the “brain” interpreting them to compute position. Both are required for GPS to work properly.

What is a GPS antenna used for? In short, it’s used to enable GPS devices to determine where they are. Without a proper antenna, a GPS receiver cannot pick up satellite signals reliably. GPS antennas are embedded in or attached to all sorts of devices that provide positioning and navigation. Some common applications include:

Smartphones and Tablets: Every modern phone has an internal GPS/GNSS antenna to help with mapping apps, ride-sharing, fitness tracking, and more.
Vehicle Navigation Systems: Car GPS units and in-dash navigation rely on either built-in or external vehicle GPS antenna modules for route guidance, emergency locating, and tracking.
Aviation and Marine: Airplanes, helicopters, ships, and boats use GPS antennas for navigation, ensuring they know their precise location, course, and speed.
Surveying and Mapping Equipment: Land surveyors use high-precision GPS or GNSS antennas (often on tripods or poles) to map coordinates accurately for construction, agriculture (e.g. precision farming), and geodesy.
Timing and Infrastructure: Communication networks, power grids, and financial systems use GPS antennas with receivers to get accurate timing signals from GPS (since the satellites carry very precise clocks).

In essence, GPS antennas allow devices across many industries to receive location and timing data from satellites. Typically, a GPS receiver needs signals from at least four satellites for a complete 3D fix (latitude, longitude, altitude, plus time). A good antenna maximizes the chance of receiving enough satellite signals for a reliable and accurate position. They are crucial for everything from getting driving directions to timestamping financial transactions.

Types of GPS Antennas (Internal vs External, Patch, Helix)

GPS antennas come in various designs and form factors, each suited for different situations. Broadly, we can categorize them as internal or external, and by their design type:

Internal Antennas: These are built into devices (like the small antenna inside a smartphone or a handheld GPS unit). Internal antennas are usually compact patch antennas or chip antennas. They are convenient and protected inside the device’s body. However, because they are small and enclosed, they may not capture signals as strongly as larger externals. (Yes, phones do have a GPS antenna – it’s just hidden!)
External Antennas: External GPS antennas are separate units that are connected to a GPS receiver via a cable (common connectors include SMA, MCX, or Fakra in cars). They can be placed in an optimal location (such as on a car’s roof) for better sky view. External antennas tend to be larger and often have higher gain. For example, an external car GPS antenna for a car stereo or tracker might be a small puck or magnetic mount module that you stick on the dashboard or roof for stronger reception. (For instance, many cars use a blue Fakra connector for the GPS antenna cable, while some handheld GPS receivers or drones use small SMA or MMCX connectors for their external antennas.)
Patch Antennas: A very common type, these are flat, tile-like antennas (often a ceramic patch) tuned for GPS frequencies. Patch antennas are typically used both internally and externally due to their low profile. They work best when facing the sky (horizontally oriented).
Helical Antennas: These antennas use a coiled wire shape (helix). They are often seen on older handheld GPS receivers and some high-end GNSS units. Helical antennas (including quadrifilar helix designs) are great at receiving signals from low on the horizon and are less sensitive to orientation. They are often used in applications where the antenna’s angle might change (like a handheld device).
Chip Antennas: A tiny antenna used on some compact devices. They save space but generally have lower gain, meaning weaker signal reception compared to patch or helix antennas.
Multiband GNSS Antennas: While a “GPS antenna” traditionally means one that receives the GPS satellite system, many modern antennas are designed to receive multiple satellite constellations (GNSS). These multiband antennas can pick up GPS, GLONASS, Galileo, BeiDou, etc., and often multiple frequencies (like L1, L2, L5). They are essential for high-precision applications.

Each type has its advantages. For instance, internal antennas make devices sleek and portable, whereas external antennas can drastically improve reception by being optimally placed and larger in size. In challenging environments or professional settings, external and multiband antennas are preferred for their superior performance.

Active vs. Passive GPS Antennas: What’s the Difference?

One important distinction is whether a GPS antenna is active or passive. This refers to whether the antenna has a built-in amplifier or not.

Passive GPS Antenna: A passive antenna is just the antenna element itself with no amplification. It simply collects the satellite signals and sends them down the cable to the receiver. Passive antennas do not require power. They are simple and can work well when the antenna is very close to the receiver (such as inside a phone or on a short cable run). However, because GPS signals are extremely weak by the time they reach Earth, any loss in the cable or connectors can degrade a passive antenna’s signal. Thus, passive antennas are best used when the antenna can be very near the receiver (to minimize cable loss) and where there isn’t a lot of interference or blockage.
Active GPS Antenna: An active antenna has an integrated low-noise amplifier (LNA) circuit. This amplifier boosts the strength of the incoming GPS signals right at the antenna before sending them to the receiver. Active antennas do require power – typically a few volts supplied through the antenna cable (a method called “bias-T” or coaxial power). Most GPS receivers in cars, drones, etc., provide a DC voltage output to power an active antenna automatically. The current draw of an active GPS antenna is usually small (on the order of 10–30 mA, which is just a tiny fraction of a watt). How do you power an active GPS antenna? Usually, the GPS receiver or device will supply power through the same cable that carries the signal. You don’t usually need a separate power cord; you just plug the antenna in, and the device powers it internally.

How much power does a GPS active antenna consume? It varies by model, but generally only around 0.1 watts or less. For example, an active antenna might use 3.3 V at 20 mA (which is 0.066 W). Some high-gain antennas might draw a bit more, but they are designed to be power-efficient since many run on battery-powered systems.

In modern designs, passive antennas are common in devices like smartphones or fitness wearables because the antenna can sit just inches away from the GPS receiver chip (minimizing any signal loss) and it draws no power. Active antennas are preferred when the antenna must be farther from the receiver or when maximum sensitivity is needed. These active units often also include built-in filters to block interference from other radio signals (like strong cell towers or Wi-Fi), which, combined with the LNA, greatly improves the signal-to-noise ratio.

The benefit of an active GPS antenna is that it can greatly improve signal quality, especially if you have a long cable run or are in a marginal signal area. By amplifying the signal at the source, it overcomes cable losses. Almost all automotive GPS antennas, marine GPS antennas, and survey-grade antennas are active.

To summarize the differences, here’s a quick comparison:

Feature	Active GPS Antenna	Passive GPS Antenna
Amplifier built-in?	Yes (LNA amplifies the signal)	No (no amplification)
Power requirement	Yes – powered via coax cable (e.g. 3–5 V, ~10–30 mA)	None (draws no power)
Cable length tolerance	Longer – amplification can overcome cable loss, so can be placed farther from receiver	Short – must be near receiver to avoid signal loss
Typical usage	External antennas (vehicles, roof mounts, etc.), active GPS antenna in most aftermarket GPS setups	Internal antennas (phones, small modules) or very short connections
Advantage	Stronger signal, better in weak-signal areas or long cable runs	Simpler, no power needed, lower cost
Disadvantage	Requires power; slightly more complex circuitry	Weaker signal if cable is long; can’t drive long cables; more prone to noise on long runs

As shown, active vs passive GPS antennas each have roles: passive antennas for short-range, power-sensitive uses, and active antennas for robust performance in vehicles and equipment. In practice, if you have the option, an active antenna usually provides more reliable reception.

Placement of GPS Antennas for Best Reception

Even the best antenna won’t perform well if it’s poorly placed. Where should I put my GPS antenna in my car? Ideally, in a location with a clear view of the sky. In vehicles, common spots include on the dashboard near the windshield or on the roof. Many external car GPS antennas have a magnetic base, allowing you to stick them on the metal roof. The roof is often the best location because it offers a 360-degree view of the sky. If roof mounting isn’t possible, placing the antenna on the front dash, as far forward (near the windshield) as possible, usually works. The windshield glass and plastic dash don’t significantly block GPS signals, but metal parts of the car will. Make sure the antenna isn’t directly under a metal roof or hood.

Where is the best place to put a GPS antenna on a car? Center of the roof is a top choice, or near the top of the windshield. Some cars have an embedded GPS antenna in the “shark fin” antenna assembly on the roof. The key is a clear view of the sky above. GPS signals come from satellites in various directions overhead, so the more sky visible, the better.

Does a GPS antenna need a line of sight? Essentially yes — the signals are line-of-sight radio waves. They don’t penetrate Earth (so underground won’t work) and are very weak inside buildings or under heavy cover. They can go through glass, plastic, and thin roofs with some loss. So while you don’t need direct eyeball visibility of a satellite, any solid obstruction (especially metal or concrete) will weaken the signal. In a car, that’s why mounting an antenna outside or at the windshield is important. Does a GPS antenna need a clear view of the sky? For optimal performance, absolutely yes. The more open sky the antenna “sees,” the more satellites it can lock onto, and the stronger the signals.

Other placement tips:

Beware of coated windshields: Some car windshields have metallic coatings (for defrosting or sun protection) that can weaken GPS signals. In such cases, mount the antenna outside or use the designated clear section of the windshield (often near the rear-view mirror) without coating for better reception.
Keep it upright: Most GPS antennas are designed to face the sky. If you mount one sideways or upside down, it may not receive as well.
Avoid close proximity to other antennas or electronics: For instance, if your car has a big radio antenna or a cellular antenna, don’t place the GPS antenna right next to it. Give it some distance to reduce interference.
Secure it: If using a magnetic mount on a car, make sure the surface is clean and flat. If placing on a dash, consider using double-sided tape or Velcro to keep it from sliding around.

By paying attention to placement, you ensure your antenna can do its job properly. Many “weak GPS signal” issues ultimately trace back to a poor antenna location.

Improving Weak GPS Signals: Boosters, Amplifiers, and Indoor Use

What if you’re still getting poor GPS reception? There are ways to boost GPS signals and fix weak reception issues.

Do GPS signal boosters work? You might have heard of GPS signal boosters or seen gadgets marketed to improve GPS reception. The concept of a “GPS signal booster” typically refers to either an amplified antenna or a GPS repeater system. In general, yes, these can work when used correctly. An active antenna, as discussed, is one form of booster (it amplifies the signal at the antenna). There are also inline amplifiers that can be added on a long antenna cable to strengthen the signal traveling to the receiver. And for specialized situations, a GPS repeater can be used to bring signals indoors.

How to amplify a GPS signal? The most straightforward way is to use an active antenna with a high gain LNA. If you already have an active antenna and need more, you could use an inline GPS amplifier (a powered device that the antenna plugs into, which then plugs into the receiver) to give extra gain, though this is uncommon for most consumers. Another approach for indoor environments is to set up a GPS repeater kit. A GPS repeater consists of an antenna placed outdoors (where it has clear sky view) that is connected via coaxial cable to an indoor re-radiating antenna. The outdoor antenna receives the satellite signals and the indoor unit rebroadcasts them inside, effectively acting like an “indoor satellite”. This can allow GPS devices to work inside a garage, tunnel, or building.

Do GPS signal boosters work for cars and phones? In a car, an external active antenna is usually the best booster – by moving the “listening point” outside the vehicle, it bypasses the signal attenuation caused by the car’s frame. Many modern dashcams or nav systems come with an optional external GPS antenna for this reason. For smartphones, you cannot directly attach an external antenna (as phones lack a port for that), but you can use a GPS re-radiator indoors or in a vehicle cradle to improve phone GPS reception. Note: some smartphone “GPS signal booster” apps claim to improve GPS performance – these can refresh your phone’s GPS data or settings, but they cannot actually amplify the radio signal from satellites. At best, they might help the phone find satellites faster (by downloading assistance data), but they won’t make signals stronger.

How do I fix a weak GPS signal? Here are a few tips:

Reposition the device or antenna: Move to an open area if possible. If using a phone, get closer to a window or go outside. If using an external antenna, try a higher location or different spot where obstructions are minimized.
Check connections: Ensure your external antenna (if you have one) is properly connected to the receiver and not damaged. A loose cable or broken connector can severely hurt signal quality.
Use an external or higher-gain antenna: If you’re relying on a tiny internal antenna (like in a handheld device) and have the option to plug in an external antenna, doing so can dramatically improve signals. For example, many vehicle GPS trackers or aftermarket navigation units support an external vehicle GPS antenna – using it can fix weak reception issues inside a car.
Use a GPS repeater for indoor coverage: If you absolutely need GPS signals inside a building (e.g., testing equipment in a warehouse or keeping a GPS lock in an underground garage), consider a GPS repeater system. Be aware that re-radiating GPS signals may require permission in some jurisdictions, as the GPS frequencies are controlled. (For instance, some countries require a license to use a GPS repeater because it rebroadcasts on the same frequencies.)
Reduce interference: Keep the GPS device/antenna away from devices that emit radio interference. For example, some dash cameras, Bluetooth transmitters, or other electronics might interfere with GPS if placed too closely.
Ensure updated software: If using a phone or dedicated GPS, make sure its software or firmware is up to date. Sometimes algorithm improvements can lead to better signal handling and faster fixes. Also, on a phone, toggling airplane mode or using a GPS status app to refresh satellite data (AGPS) can resolve glitches.
Understand repeater limitations: If using a GPS repeater indoors (for example, in an aircraft hangar or large garage), remember that all receivers will effectively see the location of the repeater’s antenna (which is usually outside). This means you won’t get an actual indoor position, but the repeater allows devices to stay locked on and in sync while inside.

By following these steps, you can often turn a frustrating weak signal into a usable one. In remote or challenging environments, you might also explore specialized solutions like high-sensitivity receivers or antennas with ground planes that enhance gain, but generally the methods above suffice for common situations.

How to get GPS signal indoor? As mentioned, the practical way is to use a GPS repeater or to place an antenna outside and run a cable indoors to your receiver (if your device allows an external antenna input). Some people also position a dedicated GPS receiver at a window and then share the location via a local network – for example, a Bluetooth GPS receiver sitting by a window can feed location to a laptop deep indoors. But generally, standard GPS is not designed for indoor use, so these workaround solutions are needed for continuous indoor coverage.

Understanding RTK and Differential GPS for High Precision

Standard GPS is accurate to within a few meters for civilian use, which is fine for everyday navigation. But some applications require centimeter-level accuracy. This is where RTK and other differential GPS techniques come into play.

What is an RTK antenna? RTK stands for Real-Time Kinematic, a high-precision GPS/GNSS technique. An RTK antenna is essentially a high-quality GNSS antenna used in an RTK system. These antennas are usually larger, often dome-shaped or choke-ring designs, and are capable of receiving multiple frequencies (like L1, L2, L5 for GPS and similar bands for GLONASS/Galileo). The purpose of an RTK antenna is to capture signals with minimal distortion, allowing the receiver to use carrier-phase data from the satellites. In an RTK setup, you have two units: a base station (at a known fixed location) and a rover (moving unit). Both use RTK antennas. The base sends correction data to the rover, enabling the rover’s receiver to fix errors and achieve centimeter-level accuracy in real time.

What is the difference between GPS and RTK? In casual terms, using GPS alone gives you a position that might be off by a few meters. RTK, on the other hand, can give positions accurate to a couple of centimeters or even millimeters. The difference isn’t in the satellites (they’re the same GPS satellites) but in how the signals are used. RTK uses the phase of the radio waves and corrections from a nearby base station to eliminate most errors (like atmospheric delay, satellite clock errors, etc.). So, the “RTK antenna” itself isn’t magically more accurate, but it is built to higher specs (to receive dual frequencies, to minimize signal phase center variations, etc.), and it’s part of a system that yields far greater accuracy. RTK antennas also often support not just GPS, but other constellations (making them GNSS antennas) to get as many signals as possible.

Where to mount an RTK antenna? For the base station, the antenna should be mounted on a very stable spot with an extremely clear view of the sky (no nearby trees, buildings, or anything that could block or reflect signals). Surveyors often mount base antennas on a tripod over a known survey marker, or on a building rooftop. The rover’s RTK antenna (say on a surveying pole or on a tractor for precision farming) also should be as high and unobstructed as feasible – for example, on top of a pole or vehicle roof. The idea is to minimize obstructions and multipath (signal reflections). RTK antennas sometimes have ground planes (a flat metal disc under the antenna) to block ground reflections and improve accuracy. So whether base or rover, high and open is the rule for placement.

What is the difference between RTK and differential GPS? “Differential GPS” (DGPS) is a broader term that refers to any technique where you use a second receiver at a known location to help correct errors. RTK is actually one form of differential GPS – a very precise one that uses real-time carrier-phase corrections. However, in common usage, DGPS often refers to older methods using only code-phase corrections or satellite-based augmentation. For example, WAAS in North America or EGNOS in Europe are space-based DGPS systems that improve GPS accuracy to within a meter or so by sending correction data from geostationary satellites. Traditional DGPS might also refer to using a single-frequency receiver with corrections from a reference station (yielding sub-meter accuracy). RTK typically implies using carrier-phase (requiring dual-frequency measurements) and can get the accuracy down to centimeters. It also usually requires a direct communication link (radio, internet) between base and rover to send the data in real time.

In summary:

GPS (Standalone) – one receiver, meter-level accuracy.
DGPS (Differential GPS) – using corrections from a base or network, can be sub-meter (or better) accuracy. This includes SBAS systems like WAAS.
RTK – a specific high-end differential technique using carrier-phase, with a dedicated base station, achieving centimeter accuracy.

For those needing extreme precision (surveying, machine control, autonomous vehicles), RTK is the go-to solution, and it requires quality RTK-capable GNSS antennas and receivers.

RTK is commonly used in applications like land surveying (mapping property boundaries and construction sites), precision agriculture (auto-steering tractors with centimeter accuracy), drone mapping, and construction machine control. These systems require more setup and investment (including radios or cellular links for the corrections), but they deliver incredibly precise results.

You might notice we’ve been using “GPS” and “GNSS” somewhat interchangeably in discussing antennas. What is a GNSS antenna? GNSS stands for Global Navigation Satellite System, an umbrella term that includes not only GPS (the U.S. system) but also others: GLONASS (Russia), Galileo (EU), BeiDou (China), and more. A GNSS antenna is simply an antenna that can receive signals from multiple satellite systems, not just GPS. In contrast, a “GPS antenna” might be limited to the frequencies used by GPS satellites alone.

What is the difference between a GPS antenna and a GNSS antenna? Primarily the frequency range and design. GPS currently mainly uses signals at 1575 MHz (L1) and 1227 MHz (L2) and newer L5 (1176 MHz), whereas other systems have their own frequencies (many of which are close to the GPS ones, but not identical). A GNSS antenna is built to be broadband or multi-band so it can handle all these frequencies simultaneously. For instance, a GNSS antenna for surveying might receive GPS L1/L2, GLONASS G1/G2, Galileo E1/E5, and BeiDou B1/B2 signals all with one antenna. This requires a wider bandwidth design or multiple resonant elements. A simple GPS-only antenna might only focus on L1 (1575 MHz) which is fine for basic navigation but wouldn’t capture the others.

In everyday conversation, people might say “GPS antenna” to mean any antenna that picks up satellite navigation signals. In fact, most standalone antennas you buy today for cars or drones are actually GNSS antennas (they’ll specify coverage of GPS/GLONASS etc.), because using multiple constellations gives more satellites in view and better accuracy. Unless you have a very old or specialized receiver that only listens to GPS, a GNSS antenna is beneficial.

What does GNSS stand for? As noted, Global Navigation Satellite System – essentially any satellite system for navigation and timing. So GPS is one GNSS (the first and most famous one).

What is a GNSS smart antenna? This term refers to an integrated device that combines a GNSS antenna and a GNSS receiver in one unit (and often a processor, and output interface). For example, in precision agriculture or surveying, you might use a “smart antenna” device that you mount on your tractor or tripod which not only receives the satellite signals but also computes the position solution internally and maybe even stores data or outputs corrections. It’s “smart” because it’s not just a passive sensor; it’s doing the GPS/GNSS processing too. An example is a USB GPS puck for a laptop – often marketed as a “GPS antenna”, it actually contains the receiver chip inside the housing, delivering location data over USB. Many modern products like the Garmin GNSS smart antenna series or Septentrio’s smart antennas are all-in-one: just give them power and they give you position info. This simplifies setup (no separate receiver box and antenna with cable; instead one unit handles everything).

In summary, GNSS antennas are the more encompassing upgrade to GPS-only antennas, and they are critical for high accuracy and reliability (using multiple systems). If you see a spec sheet that says an antenna supports GPS/GNSS, it’s likely a good thing as it means more satellites to use.

One practical difference to mention is cost: a basic passive GPS antenna (for example, the kind used in a car or small gadget) can cost just a few dollars, whereas a survey-grade multi-band GNSS antenna with high precision can cost hundreds or even thousands of dollars. The complexity and precision engineering of GNSS antennas drive up the price, so the choice often depends on budget as well as performance needs.
