HoTT Alpha GPS and Vario Module

P/N: S8437


Utilizing u-blox 8 GPS receiver technology and GPS/GLONASS satellites, the Graupner HoTT Alpha GPS/Vario Module is our next generation of faster and more accurate positioning services. Ideal for multirotor, airplanes, cars and boats, the GPS sensor provides real-time information on altitude, flight location, distance, speed display, travel direction display, coordinates, and more. All information can be displayed on any HoTT radio display screen and used with voice announcements to report GPS telemetry data.

Telemetry settings and module programming can be achieved wirelessly using a Graupner HoTT radio or Smart-Box (P/N 33700, sold separately).  Log your GPS telemetry data to an SD memory card for evaluation via the Graupner Studio Program or Google Maps.

This GPS vario module works good easy to program on the mz24 Hott transmitter. Shipping from Grauper is great, the only thing the is that the manual doesn't show which is front or back only talks of label facing up on the module . No north making needs a youtube video on set up on the module and how to do firmware upgrade programming the radio after firmware upgrade 1.055 screen display is difference to the Manuel for GPS module
