What is required for TruTrak Autopilots to operate?
A – The only thing that is required to get the full functionality of any TruTrak autopilot with a roll axis servo is a GPS RS-232 signal. The RS-232 must be either NMEA 0183 (GPRMC and GPRMB sentence in the data string) or Aviation format. The desired update rate is every second, but the system will function at an update rate as slow as every other second. For systems with pitch axis control nothing is needed in addition to the programmer and servos provided by Trutrak.
