Configuring Differential GPS
For the receiver to output GPS position coordinates of submeter
accuracy, you must first select a differential signal from one of the
following sources:
• WAAS/EGNOS – free service, limited availability
The Wide Area Augmentation System (WAAS) augments GPS
with additional signals for increasing the reliability, integrity,
accuracy, and availability of GPS in the United States. The
European Geostationary Navigation Overlay System (EGNOS) is
the European equivalent of WAAS.
