The Satellite Status Page also indicates the accuracy of the position fix, using Estimated Position Error (EPE), Dilution of Precision (DOP), and Horizontal Uncertainty Level (HUL) figures. DOP measures satellite geometry quality (i.e., number of satellites received and where they are relative to each other) on a scale from one to ten. The lowest numbers are the best accuracy and the highest numbers are the worst. EPE uses DOP and other factors to calculate a horizontal position error, in feet or meters. HUL is explained in Section 15.

 

GPS Receiver Status Messages

Searching Sky

The GPS receiver is searching the sky for ANY visible satellites. The

 

pilot is informed of this status with a ‘Searching the Sky’ message.

Acquiring Sat

The GPS receiver is acquiring satellites for navigation. In this mode,

 

the receiver uses satellite orbital data (collected continuously from

 

the satellites) and last known position to determine which satellites

 

should be in view.

2D Navigation

The GPS receiver is in 2D navigation mode. Altitude data is provided

 

by an altitude serializer.

3D Navigation

The GPS receiver is in 3D navigation mode and computes altitude

 

using satellite data.

Poor Coverg

The GPS receiver cannot acquire sufficient satellites for navigation.

Rcvr Not Usbl

The GPS receiver is unusable due to incorrect initialization or

 

abnormal satellite conditions. Turn the unit off and on again.

AutoLocate

The GPS receiver is looking for any available satellite. This process

 

can take up to five minutes to determine a position.
