GPS Information Page
The GPS Information Page displays your speed, elevation, the estimated
accuracy, receiver status, satellite locations, satellite signal strength, the date, time
and the GPS receiver’s current location.
Speed, Elevation and Estimated Accuracy
When the GPS is receiving at least three satellite signals, it will provide you
with the current GPS Speed, and the estimated Accuracy of the GPS Location.
The GPS must be receiving at least four satellite signals to report the Elevation.
Current GPS Receiver status
The current status of the GPS receiver will always be displayed.
Autolocate —
Forces the receiver to search for each satellite individually.
Acquiring Satellites —
The receiver will begin in this mode each time the unit
is turned on. The GPS receiver will remain in this mode until it has acquired
at least 3 satellite signals.
2D GPS Location —
Indicates that the receiver is only using three satellite
signals. When a 2D GPS Location is achieved, the GPS will display your
current position but is incapable of providing an altitude reading.
3D GPS Location —
Indicates the receiver is currently using at least four
satellite signals and is capable of providing your current position and altitude.
2D Differential Location —
Indicates the receiver is using DGPS or WAAS
differential data on three satellites.
3D Differential Location —
Indicates the receiver is using DGPS or WAAS
differential data on at least four satellites.
Lost Satellite Reception —
Indicates that the GPS receiver has lost satellite
reception.
Simulating GPS
— Indicates the GPSMAP 76 is running in Simulator Mode and
the GPS receiver is turned off. It is important to remember when you are
using the Simulator, the GPSMAP 76 can not be used for actual navigation.
