Turn off the receivers when the observation is completed.
Moving to the Next Session
Thus far, we have discussed the process for collecting one session of data,
establishing baselines between the known point and all unknown points. For instance,
if four receivers were used in the previously discussed survey, three unknown points
would have been established. The fourth point occupied was a known point. If more
points remain to be surveyed, the receivers must move to the next set of points and a
new session of data collection must be performed. Keeping in mind that one receiver
must remain on a known point, this is often accomplished by leaving one of the
receivers on the previous session point. This point acts as the pivot point for all the
other receivers. This point is now known because it was surveyed in the last session.
When all the other receivers are again set up, the second session can begin. Normally,
session start and stop times are determined prior to leaving the office. All operators
are made aware of this schedule, along with the point assigned to them for
