GPS & ADS-B Portable Buyers Guide

Quick answer: For most pilots, the best all-in-one portable ADS-B receiver is the Garmin GDL 52 ($1,360), which adds SiriusXM and AHRS. The best value ADS-B pick is the Garmin GDL 50 ($850), with the Appareo Stratus 4 ($849) a strong alternative. If you only need better GPS position, the Garmin GLO 2 ($140) or Dual SkyPro XGPS160 ($169.99) are the picks.

Is your cockpit ready for the FAA's NextGen air traffic control system? Getting real-time traffic and weather used to cost thousands in equipment and subscription fees.

Today, many pilots can add subscription-free ADS-B weather and traffic to a tablet setup with a compact receiver on the glare shield (plus the right app).

Portable ADS-B and GPS Receivers Compared

Does a Portable ADS-B Device Meet FAA Requirements?

Portable receivers are great for ADS-B In (subscription-free weather and traffic on your tablet), but they do not make an aircraft "ADS-B Out compliant."

To fly in ADS-B rule airspace, the aircraft needs an installed ADS-B Out transmitter paired with an approved position source that meets the FAA's performance requirements (14 CFR 91.225 and 91.227).

The good news: for ADS-B In, you typically pay for the receiver once, and there are no FAA subscription or usage fees for the broadcast services (your flight app may have its own subscription).

What is ADS-B?

ADS-B stands for Automatic Dependent Surveillance-Broadcast. In simple terms, it is a modern surveillance system that uses satellite-based position data to improve how aircraft are tracked and separated.

How ADS-B Works

Aircraft equipped with ADS-B Out transmit their position, altitude, velocity, and other data. Ground stations and other aircraft can receive that information, improving situational awareness.

If you also have ADS-B In, you can receive FAA broadcast services on compatible equipment, typically including traffic and weather products displayed on a cockpit MFD or a tablet.

One important detail: FAA's FIS-B weather broadcast is available on the 978 MHz UAT link (not on 1090ES). Depending on the receiver you choose, that may affect what you can receive. The dual-band receivers below (GDL 50/52 and Stratus 4) listen on both 978 UAT and 1090ES.

ADS-B Out Usage

Most airliners and many turbine aircraft are equipped with ADS-B Out, and many GA aircraft have been upgraded as well.

However, not every older airplane is equipped. If your aircraft does not have installed ADS-B Out, you may still fly outside ADS-B rule airspace (subject to other requirements), but you will want to understand the airspace rules before you launch.

If you are building a more complete traffic picture, remember that ADS-B In traffic is not the same as "seeing everything." Some traffic solutions add additional inputs (like transponder-based traffic) to help fill in gaps.

If you are ready to explore portable options, take a look at these receivers:

Garmin GDL Series (ADS-B In Receivers)

Garmin's portable GDL receivers bring ADS-B In weather and traffic to compatible apps, plus GPS position data. The two current models are the GDL 50 and the all-in-one GDL 52.

Compatibility note: Always confirm your specific receiver model is supported by the flight app you plan to use (the GDL series pairs natively with Garmin Pilot and is also supported by ForeFlight).

• Garmin GDL 50 ($850): Dual-band (978 UAT + 1090ES) portable ADS-B In receiver delivering subscription-free FIS-B weather, traffic, and GPS position. Best value for pilots who want ADS-B In without SiriusXM.
• Garmin GDL 52 ($1,360): Adds SiriusXM satellite weather and audio (subscription required) plus a built-in AHRS for backup attitude, on top of dual-band ADS-B In. The best all-in-one pick.

• Dimensions: Approximately 4.9" x 1.3" x 3.4" (varies slightly by model)
• Battery: Rechargeable lithium-ion
• Connectivity: Bluetooth to your tablet, plus wired power options

Appareo Stratus 4 (ADS-B In Receiver)

The Appareo Stratus 4 ($849) is a current-generation dual-band (978 UAT + 1090ES) portable ADS-B In receiver. It delivers subscription-free FIS-B weather and traffic, GPS position, and a built-in AHRS for backup attitude. It is the natural pick for ForeFlight users and is distinguished by a color status touchscreen and a replaceable battery.

• Receives: ADS-B In weather and traffic, GPS, plus AHRS attitude
• Bands: Dual-band 978 MHz UAT and 1090ES
• Notable: Color touchscreen status display and user-replaceable battery

Availability note: the Stratus 4 can sell out; confirm current stock on the product page.

Dual SkyPro XGPS160 (Bluetooth GPS Receiver)

The Dual SkyPro XGPS160 ($169.99) is a Bluetooth GPS receiver. It improves position accuracy and reliability for tablets and EFB apps, and it can share its GPS signal with multiple devices at once.

Important: The XGPS160 is a GPS receiver. It does not provide ADS-B weather or ADS-B traffic by itself. Pair it with an ADS-B In receiver if you want subscription-free traffic and weather.

• Dimensions: Approximately 2.7" W x 2.2" H x 0.8" thick
• Battery Life: Around 10 hours (typical use)
• Connection Type: Bluetooth (multi-device support), USB charging
• Compatible With: Many iOS/Android apps that accept external GPS

Garmin GLO 2 for Aviation (Bluetooth GPS Receiver)

The Garmin GLO 2 ($140) is also a Bluetooth GPS receiver. It can use both GPS and GLONASS satellites, which may help with acquisition and coverage in some conditions.

Important: Like the Dual, the GLO 2 provides position data only. It does not provide ADS-B weather or ADS-B traffic by itself.

• Battery Life: Up to about 12 hours (typical)
• Connection Type: Bluetooth and USB
• Compatible With: Many EFB apps that accept external GPS receivers

FAQs

• What is the best portable ADS-B receiver?

  For most pilots the Garmin GDL 52 ($1,360) is the best all-in-one choice because it adds SiriusXM and a backup AHRS. If you want subscription-free ADS-B In at a lower price, the Garmin GDL 50 ($850) is the best value, and the Appareo Stratus 4 ($849) is a strong dual-band alternative, especially for ForeFlight users.

• Stratus 4 vs Garmin GDL: which should I buy?

  Both are current dual-band (978 UAT + 1090ES) ADS-B In receivers with built-in AHRS. The Stratus 4 ($849) pairs naturally with ForeFlight and adds a color status touchscreen and replaceable battery. The Garmin GDL 50 ($850) and GDL 52 ($1,360) integrate tightly with Garmin Pilot, and only the GDL 52 adds SiriusXM weather and audio.

• Can I fly without ADS-B Out?

  Yes, depending on where you fly. ADS-B Out is required in ADS-B rule airspace, but there are places you can fly outside that airspace without it. Always verify the specific airspace requirements for your route.

• Does ADS-B In make my aircraft ADS-B compliant?

  No. ADS-B In is for receiving traffic and weather. ADS-B Out is what the FAA requires for operating in ADS-B rule airspace under 14 CFR 91.225.

• Do I need a subscription for ADS-B weather and traffic?

  FAA broadcast services received via ADS-B In do not require subscription or usage fees. Your EFB app may have its own subscription, and SiriusXM (on the GDL 52) is a separate paid service.

• Will I get weather on any ADS-B receiver?

  Not always. FAA's FIS-B weather broadcast is available on 978 MHz UAT. If your setup only receives 1090ES, you will not receive FIS-B weather through ADS-B. The GDL 50/52 and Stratus 4 are dual-band, so they receive FIS-B weather.

• Do GPS receivers like the GLO 2 or XGPS160 provide traffic and weather?

  No. They provide GPS position to your tablet or EFB. For traffic and weather you need an ADS-B In receiver such as the GDL 50, GDL 52, or Stratus 4.
