Surveying with ProMark2
our 3-point control survey network design, shown again in Figure 3.6.
Assume that a 2-receiver ProMark2 system will be used to perform the survey in Figure 3.6.
To produce the link between the existing control point 1 and the new point 2, simply place one
ProMark2 receiver system on point 1, place the other receiver on point 2 and simultaneously
collect data between the two points. When the observation is complete, move the ProMark2
receiver from point 2 to point 3. Perform another observation, simultaneously collecting data
on points 1 and 3. When completed, move the ProMark2 receiver from point 1 to point 2.
Perform the final observation between points 3 and 2. When this data is downloaded and
processed, the result will be three vectors (delta positions) forming the network design seen in
Figure 3.6.
Now consider the situation where a 3-receiver ProMark2 system is used. By placing one
receiver on each of the 3 points in the network of Figure 3.6, the data for all three vectors can
be collected in one observation, rather than the 3 separate observations required with using a 2-
receiver system.
Now consider the observation plan for the more complex 15-point survey, shown again in
Figure 3.7.
