Receiver Status - Garmin GPSMAP 276C Owner's Manual

The progress of satellite acquisition is shown in three stages:
• No signal strength bars—the receiver is looking for the
satellites indicated.
• White signal strength bars—the receiver has found the
satellite and is collecting data.
• Green signal strength bars—the receiver has collected the
necessary data from this satellite.
When the GPSMAP 276C collects the necessary data from the best
satellites in view to calculate a fix, the status field indicates the status
of the receiver. The unit then updates the location, date, and time.

Receiver Status

The Receiver Status field shows one of the following conditions:
• Searching the Sky—the receiver is looking for satellites.
• AutoLocate—the receiver is looking for any satellite whose
almanac was collected, which can take up to five minutes.
• Acquiring Satellites—the receiver is looking for and
collecting data from satellites visible at its last known or
initialized location but has not acquired a fix.

• 2D GPS Location—At least three satellites were acquired
and a two-dimensional position fix was calculated.
"2D Differential" appears when you are receiving DGPS
corrections in 2D mode, and a "D" appears on the strength bar
of satellites being corrected.
• 3D GPS Location—At least four satellites were acquired
and a three-dimensional fix was calculated. "3D Differential"
appears when you are receiving DGPS corrections in
3D mode, and a "D" appears on the strength bar of satellites
being corrected.
• Lost Satellite Reception—the receiver is no longer tracking
enough satellites for a 2D or 3D fix.
• Receiver Not Usable—the receiver is unusable, possibly due
to interference or abnormal satellite conditions. Turn the unit
off and back on to reset.
• Simulating GPS—the receiver is in Simulator Mode.
• GPS Off—the GPS receiver is turned off.
