The GPS module receives messages from GNSS satellites and provides the Flight Controller with current global coordinates.
The GPS Patch Antenna usually has factory cut-ins to improve impedance match. One corner of the antenna is also cut, to widen bandwidth. The antenna is excited through a coaxial line, from other side of the board.
There are multiple versions of the board:
