I have a question regarding the update_GPS function in sensor.cpp file under AntenaTracker package.
In the beginning of this function there is an if condition:
if (gps.last_message_time_ms() != last_gps_msg_ms &&
gps.status() >= AP_GPS::GPS_OK_FIX_3D)
I was wondering what is the condition that are being checked in this if statement?
I’m a bit new to the ArduPilot packages, my apology if the question is naive.
