GPS Position Rover Base station NEO-M8P-2-11

In open terrain (approx. 50*50m), different positions are to be determined as accurately as possible (1-5 cm). The accuracy of the absolute position is not decisive, but the relative positions to each other are. The position data of the rover should be transferred in X,Y coordinates or as GPS data and processed with an Arduino Mega 2560. The reference station will not move while computing an accurate vector between the rover receivers reference station and the receiver's antennae. Two NEOM8P-2-11s are available and must be configured accordingly. This can be done via u-Center (the corresponding configuration files must be supplied) or directly in the software code via the Arduino.
Programming language: C++
The necessary wiring must also be specified
If sufficiently possible, the SparkFun_u-blox_GNSS_Arduino_Library should be used.
