GPS-RTK Hookup Guide
The NEO-M8P-2 module is the top-of-the-line module for high accuracy GNSS and GPS location solutions including RTK. The NEO-M8P-2 is unique in that it is capable of both rover and base station operations. The ‘-2’ designation means this module has survey-in mode allowing the module to become a base station and produce RTCM 3.x correction data. From here on we will refer to the module as NEO-M8P but it should not be confused with the NEO-M8P-0 module (which is not able to produce RTCM data).
