Humanized positioning green LED indicate.After power-on, the indicators near the antenna are always on; when the satellite is found, the indicators near the antenna are always on, and the other indicators are blinking.
Definition of Connector
Connect to PIX: Red wire-VCC, White wire-TX, Orange wire-RX, Black wire-GND, Green wire-CLK, Yellow wire-SDA
GPS Mainboard : White wire-RX, Orange wire-TX, Red wire-VCC, Black wire-GND, Green wire-CLK, Yellow wire-SDA
Direction Indicate
Arrows shows the front, point to the same direction as the flight controller.
Keep the same direction with flight controller.

GPS connect to PIXHAWKConnect to APM
6pin for GPS connect port ：Pay attention to the installation direction, the GPS direction is consistent with the flight control direction;
4pin for I2C connect port：Take off the internal compass of APM.Otherwise, there is no data even if the GPS compass is plugged in.
Compass calibrate(calibrate with APM mission planner)
Compass calibrate（Using version 1.3.39 of Mission planner）, please choose Pixhawk/PX4 if you use with PIXHWAK.

If you use with flight controller APM, please choose APM and External Compass and then click Live Calibration to calibrate the compass.
Calibrate like this picture shows, click Done to finished the calibrate. Click OK to save the settings.
