1. Q: How to access external GPS information to the gimbal?

Case 1: The gimbal is directly connected to the GPS module

Answer: 1) Change the baud rate of the GPS module to 115200, GPS has GGA or RMC information output under the NEMA-0183 protocol. 2) Cross connect TX and RX and sent the data to gimbal serial port.

Case 2: Open source flight control output GPS information to gimbal GPS

Answer: Connecting with GPS module the flight control will send GPS data GLOBAL_POSITION_INT ( #33 ) to the gimbal serial port through FC telem port (setting: 115200, Mavlink1);

Case 3: Need development: Send GPS data to the gimbal serial port through the serial port position analysis protocol or the M packet format in the Viewlink protocol.
