The “Satellites Tracked” display shows the identification numbers( ID) of
the satellites being received, tracked, and used for L/L calculations in the
reverse block characters. The
Raystar
108 sensor is usually tracking 4-6
satellites at any one time and can track up to eight, if visible. So, seeing 6 to
8 blocks illuminated is not at all unusual.
In the column below each Sat ID # you can see see the individual satellite’s
azimuth angle, it’s elevation angle from the horizon, and signal level (SNR).
The data is displayed for all satellites being received.
Below the Status box the HDOP number appears and provides the current
fix quality. This rates both the strength of the satellite signals as well as the
geometry of the satellite positions. Typical HDOP numbers for a good fix
are 2 or less. Fair HDOP values are 4 or less; Poor HDOPs are over 5.
