Now consider the situation where a 3-receiver ProMark3 sys-
tem is used. By placing one receiver on each of the 3 points
in our network, the data for all three vectors can be collected
in one observation, rather than the 3 separate observations re
-
quired with using a 2-receiver system.
Now consider the observation plan for the more complex 15-
point survey, shown again below.
To execute this network design, you must perform a direct
GPS observation between all points directly linked. Each link
can be viewed as a required GPS vector. Counting the links in
this network design, you will find that 19 GPS vectors are re
-
quired to execute this design.
If the survey was to be performed using a 2-receiver ProMark3
system, 19 separate data collection sessions (observations)
would be required. For example, you can start with a receiver
on point 1 and another on point 2. After this observation, you
would move the receiver from point 1 to point 3 to perform an
observation between points 2 and 3, and so on until all vectors
were observed.
