Bad Elf GPS Pro+: Barometer, GLONASS

Navigation apps require reliable GPS position input for georeferencing, which is the ownship data that’s displayed on electronic charts and maps. The built-in GPS on many tablets might not be reliable enough without cell phone tower assist, especially in the cabin at higher altitudes. That’s why a wireless GPS receiver remains an integral component for cockpit tablet use.

Navigation apps require reliable GPS position input for georeferencing, which is the ownship data that’s displayed on electronic charts and maps. The built-in GPS on many tablets might not be reliable enough without cell phone tower assist, especially in the cabin at higher altitudes. That’s why a wireless GPS receiver remains an integral component for cockpit tablet use.

On the other hand, WAAS-equipped portable ADS-B receivers fill that need, leaving a dwindling market for standalone receivers like the new $300 Bad Elf GPS Pro+.
