RCGPS-F3x is a GNSS satellite positioning receiver specifically designed for F3x model gliders.
It supports four different GNSS satellite systems and can simultaneously lock onto up to 32 satellite signals providing exceptional positional accuracy 1.5m CEP. Even in high-dynamic scenarios ( > 4G ) over short periods, it experiences minimal satellite signal lock loss.
Additionally, the telemetry features low latency and high transmission rates by supporting ubx binary protocol with 912600 baud instead of NMEA protocol with 38400 baud.
For F3x task, it supports multi telemetry protocol and F3x lua script running on various transmitters.
Overall it has good positioning accuracy and no sensable delay.
