Third NAV2/POS display: the Satellite skyplot.

This display shows satellites in sight by the Sensor unit, and which satellites the HS50 is tracking. The satellites are presented according to satellite geometry. The bars on the left side of this display indicate the signal-to-noise level for each satellite.

Info displays

When pressing the INFO button, the system will page through a number of displays for information about system configuration and performance. The information on some of these displays is mainly used for troubleshooting the system.

In the GPS information display details for the position solution is presented. This information is mainly for trouble shooting of the system.

An explanation of the information shown is as follows:

Quality indicators for the GPS solution.

Estimated accuracy on the position solution (RMS). Estimated RMS accuracy on the velocity solution (RMS).

Average signal-to-noise ratio on the GPS receiver 1 and 2.

Age of differential corrections. If HS50 receives no differential correction, the displayed correction age will be high. See No Differential corrections, page 47 for trouble shooting loss of differential signal.

Actual reference station utilized in the position solution. World time referred to UTC.
