The pop-up dialog box shows the current GPS status, and, for purely
informational purposes, the number of satellites used for position fix, and the
current geolocation of the GPS receiver, in degrees and decimal minutes
format.

When the MU100090A is installed, the following buttons and the elapsed times
appear in the pop-up dialog box.
MU100090A PowerMU100090A Power: Touch the button to turn on the MU100090A power or turn
off.
Antenna PowerAntenna Power: Touch the button to set the feeding power voltage to the
antenna.
J1706A GPS Antenna accepts both voltages.
Sync ModeSync Mode: Touch the button to select the signal to use to the built-in Rubidium
Oscillator synchronization.
Power On Elapsed TimePower On Elapsed Time: Displays the time elapsed since the MU100090A
power was turned on.
OSC. Lock Elapsed TimeOSC. Lock Elapsed Time: Displays the time elapsed since the built-in
Rubidium Oscillator has reached the stability of 10
−9
(OSC indicator on the
MU100090A panel has turned on).
Sync. Mode Elapsed TimeSync. Mode Elapsed Time: Displays the time elapsed since the built-in
Rubidium Oscillator was locked to the reference signal.
When the phase-locked condition is lost, this value is reset to 0.
When the MU100090A is connected to the GPS, the number of captured
satellites and the GPS antenna position (latitude, longitude, and altitude
(ellipsoidal height)) are displayed.
The ellipsoidal height is the altitude from the ellipsoid surface that virtually
represents the Earth from the results of gravity and leveling surveys.
