10.1 Network DGPS
Overview Standalone mojo3D systems (that is, those not connected to a mojoXact/mojoXact
Plus) provide DGPS (Differential GPS) position type. Network DGPS utilises a network
of base stations or single base stations to provide differential GPS correction signals
via the cell phone network.
Benefit The Network DGPS option for the mojo3D provides an increase in accuracy over the
standard product. This accuracy increase is most pronounced in the absolute position
and not so much in the pass to pass. The absolute accuracy of the mojo3D with
Network DGPS is reduced to 0.50 meters RMS, however this accuracy is impacted by
the distance to the base station. Excellent performance improvements can be
achieved with base stations in the order of 150km away.
