4.Navigation Mode
The receiver is in Navigation mode whenever sufficient satellite information and measurement data is available to produce a GPS fix. Navigation mode is entered from Acquisition or Dead- Reckoning mode and exits to
In Navigation mode, a receiver configured as a roving unit operates in 2
a.Differential (Roving Unit Only)
The receiver operates in Differential mode when data from at least 4 satellites with adequate geometry and differential corrections and/or measurements exist to compute position, velocity and time outputs. This is the preferred navigation mode. Differential data is supplied to the receiver through the differential input port. Differential data can be received only on the COM2 (DGPS IN) serial data port.

The receiver operates in
c. Base Station Nav (Base Station Unit Only)
The receiver operates in Base Station Nav mode once the time has been initialized and at least 4 satellites with adequate geometry can be used for navigation purposes. Once in this mode, only a change of configuration (rover mode requested) or a reset will cause the unit to leave this navigation mode. In this mode, the unit will have the ability to transmit the DGPS messages which are requested and allowed once its position is initialized. See also Section 3.5, Configurable Parameters starting on Page 23 for position initialization details.
Your receiver must be a BASE model to act as a base station. A list of models may be found in Appendix A of the SUPERSTAR II Firmware Reference Manual, see Reference [6] on Page 12.
5.Dead-Reckoning Mode
The receiver enters
6.Fault Mode
The receiver enters Fault mode during the period of time in which the receiver outputs are affected by one or more critical system faults. This mode supersedes all others and remains active until the next
