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. 

 

When pressing the 

 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: 

HDOP 
PDOP

Estimated RMS accuracy on the velocity solution (RMS). 

Average sn gps1 
Average sn gps2 

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

Correction age 

Age of differential corrections. If HS50 receives no differential 
correction, the displayed correction age will be high. See No
