Signal

Sky view
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 376C 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.
