There are two windows in this display. The left window has twelve
'graphic Power Bars representing the twelve GPS receiver channels of
the MX42 I antenna. The
PRN
(PseudoRandom Number) under each
power bar represents the satellite ID number assigned or being tracked
on that channel. The power bars indicate the valid receiver power
range from 30 to 50. Any portion of the power bar which is filled in,
indicates that a satellite is being tracked on that channel. Ifa power bar
is empty, but a PRN number is labeled under the power bar, then the
identified satellite is not currently being tracked.

The graphic on the right hand side of the screen indicates where the
satellites are relative to your present position. The outer ring repre-
sents 0° elevation. The innerring represents 45° elevation. The
+
sign
represents 90° elevation and your present position. Under normal con-
ditions, the best satellites to track are usually between 15 and 75 de-
grees in elevation.
GPS 2 through GPS 5 screens are skipped under normal operation.
