SYSTEM OVERVIEW
The GP-320B is a GPS receiver with WAAS (Wide Area Augmentation System) capability.
WAAS, available in North America, is a provider in the worldwide SBAS (Satellite Based
Augmentation System) navigation system. An SBAS provider furnishes GPS signal
corrections to SBAS users, for even better position accuracy, typically better than three
meters. Two more SBAS providers are also currently under development, MSAS
(Multi-Functional Satellite Augmentation System) for Japan and EGNOS (Euro
Geostationary Navigation Overlay Service) for Europe. All providers will be compatible with
one another, thus providing “seamless” position fixes to SBAS users.
SBAS is currently in the developmental phase and SBAS providers are expected to have
initial operations capability from the times shown below. During the developmental phase
the reliability and availability of the SBAS signal cannot be guaranteed.
