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.
As soon as the GPSMAP 296 has collected 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 has been collected, which can take up to 5 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 have been acquired
and a two-dimensional location fix has been 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 have been acquired
and a three-dimensional fix has been 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.
