• AutoLocate—the receiver is looking for any satellite whose
almanac has been collected. This process 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 position, but has not collected enough data to
calculate a fix.
• 2D—at least three satellites with good geometry have been
acquired and a 2 dimensional position fix (latitude and
longitude) is being calculated. “2D Differential” appears
when you are receiving DGPS corrections in 2D mode and a
D shows on the strength bar of satellites being corrected.
• 3D—at least four satellites with good geometry have been
acquired and your location is now being calculated in
latitude, longitude and elevation. “3D Differential” appears
when you are receiving DGPS corrections in 3D mode and a
D shows on the strength bar of satellites being corrected.
• Poor GPS Coverage—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 it.
• Simulating—the receiver is in Simulator Mode.
