The post-processing activity computes vectors (position differ-
ences) to determine the position of all observed points relative
to one or more fixed point positions. The static data collection
method produces the most accurate and reliable results of any
mode of GPS data collection. This is due primarily to the ex
-
tended observation periods required for static data collection.
In the Stop-and-Go data collection mode, the GPS receiver
systems simultaneously collect raw data from all available sat-
ellites while stationary on their respective points and while
moving between points. In most cases, one GPS receiver is lo-
cated on a known point serving as a base station collecting
data at that location for the duration of the survey. Additional
GPS receivers are used to locate objects and move between
points. The occupation period for the stop-and-go method is
much shorter than the static method.
