21. RTK positioning method to achieve centimeter level accuracy To use the RTK method you must first set up a base station The base station uses a radio link to broadcast RTK corrections to one or more rover receivers The AgGPS 332 receiver is a rover receiver so another compatible receiver such as a Trimble MS750 or AgGPS 214 GPS receiver must be used as the base station AgGPS 332 GPS Receiver User Guide 9 2 Overview A transmitter in the base station sends the corrections through a radio link to the rover radio which sends the corrections to the AgGPS 332 receiver The rover receiver uses RTK corrections from the base station to calculate its position to centimeter level accuracy As part of this process the rover receiver must calculate an initialization This takes a few seconds While the receiver is initializing an RTK Float solution is generated Once initialized an RTK Fixed solution is generated It is the RTK Fixed solution that provides centimeter level accuracy The parts per million ppm error is dependent on the distance baseline length between the base and rover receiver For example if the distance is 10 km a 2 ppm error equals 20 mm For more information about RTK positioning go to the Trimble website at www trimble com gps Differential GPS positioning DGPS For differential positioning the AgGPS 332 receiver uses corrections from SBAS WAAS EGNOS OmniSTAR satellites and Radio Beacons These dif
