What to Look for When Buying a Portable Aviation GPS
Choosing the right portable aviation GPS requires understanding how different features match your specific flying patterns. Here is what my testing revealed about the factors that matter most.
WAAS GPS Accuracy is Essential
WAAS (Wide Area Augmentation System) correction transforms standard GPS accuracy from 15-20 meters down to 1-3 meters horizontally. For aviation navigation, this precision matters when identifying runways, navigating narrow valleys, or maintaining obstacle clearance. Every product in this guide includes WAAS capability because non-WAAS receivers no longer meet pilot expectations for accuracy.
Multi-constellation reception adds GLONASS, Galileo, or other satellite systems alongside GPS. More satellites in view means better accuracy in challenging reception environments and faster reacquisition if signals temporarily drop. Most modern receivers include at least GPS plus GLONASS.
ADS-B Weather and Traffic Considerations
ADS-B In capability provides subscription-free weather and traffic data within range of ground stations. The FIS-B weather products include NEXRAD radar, METARs, TAFs, winds aloft, and temporary flight restrictions. TIS-B traffic shows other ADS-B equipped aircraft, significantly improving situational awareness in busy airspace.
Dual-band reception (978 MHz UAT and 1090 MHz extended squitter) captures all traffic types including aircraft with 1090 MHz ADS-B Out only. Single-band receivers might miss high-flying jets that only transmit on 1090 MHz.
Battery Life for Your Mission Profile
Minimum acceptable battery life depends on your typical flight duration. Four hours covers most training flights and short cross-countries. Eight-plus hours supports longer trips without charging anxiety. Consider whether you will have power available in your typical aircraft and how often you fly multiple legs between charging opportunities.
Replaceable batteries offer advantages over sealed units. When battery capacity degrades after years of use, swapping a standard cell takes seconds rather than shipping the unit for service.
EFB App Compatibility
Most portable GPS receivers and ADS-B units connect wirelessly to iPad and Android EFB apps. ForeFlight dominates the US general aviation market and works with nearly every receiver tested. Garmin Pilot users get optimized integration with Garmin hardware through the Connext protocol.
Verify compatibility with your specific app and device combination before purchasing. Some receivers work better with certain operating systems; the Dual XGPS160 delivers 10Hz updates on Android but faces app stability issues, while iOS devices see lower update rates with some Garmin receivers.
Screen Readability and Mounting Options
Dedicated portable GPS units like the aera660 include built-in displays that must remain readable in direct sunlight. Look for high-brightness screens with anti-glare coatings. Tablet-based solutions using external GPS depend on the tablet display quality, which varies significantly between iPad models and Android devices.
Mounting hardware affects everyday usability. Yoke mounts position dedicated GPS units for quick scanning without head movement. Suction mounts work for temporary installations but can fail in temperature extremes. Consider whether you need the GPS to move between aircraft or stay semi-permanently installed.
