The following annotation (BLUE circle in above image) indicates the INTERNAL,
top-panel antenna status:
 Ant: INIT – antenna status initializing.
 Ant: OK – antenna present and working.
 Ant: OPEN – antenna is not drawing DC bias current. This could occur when
an active antenna is not connected properly or the antenna does not require
DC bias current. Antennas that do not require bias current can still provide an
accurate GPS reading.
 Ant: SHORT – antenna center pin has been shorted to ground. The internal
bias circuitry is disabled for about one minute, then re-enabled. You can also
press GPS OFF, then GPS Internal.to quickly re-enable the antenna bias.
