The GPS navigation states possible are:
GPS Navigation State
Operational Meaning
Self Test
System performing self test. This is
the initial state value but happens so
quickly it is rarely observed.
Init
System is initializing
– this state is
also very quick and is rarely
observed.
Search
Satellite acquisition mode.
Basic Nav
System has acquired enough
satellites to conduct basic navigation
but without integrity.
FDE Nav
System is computing a navigation
solution with integrity provided using
fault detection and exclusion.
SBAS Nav
System is computing a navigation
solution with integrity provided by
SBAS (e.g. WAAS).
Fault
System has detected an internal fault
and does not have a navigation
solution. This may require a manual
power cycle of the IFD to restore a
GPS lock.
The graphical bars represent the relative signal strength of each
individual SV as well as the SV identification number. SV
numbers above 100 represent the SBAS satellites.
The internal GPS receiver will automatically de-select satellite
vehicles from inclusion in the position fix if poor satellite health or
maintenance information is available in the satellite data stream.
