Satellite tracking gauge
The satellite tracking gauge displays the number of
satellites currently being tracked by the receiver. If the
current position of the receiver is fixed, the currently
illuminated LED flashes.
For a satellite to be counted as used, it must have a healthy signal
and be above the elevation mask, and the receiver must have
achieved lock (both code and carrier).
Table 10 summarizes the values indicated by the satellite tracking
gauge LEDs.
TIP
⇨
For the most accurate survey results, perform surveys with a minimum
of six satellites, if possible. LED 1 (red) will be illuminated if the
receiver is using only one, two, or three satellites, which are insufficient
for three-dimensional positioning applications.
