Specifications

After data collection is complete, data is downloaded from the

GPS receivers to an office computer for post-processing using

the GNSS Solutions software. The post-processing activity

computes vectors (position differences) to determine the po

sition of all observed points relative to one or more fixed point

positions. The Stop-and-Go data collection method is faster

than the static method, but not as accurate since the occupa

tion period is much shorter.

In the Kinematic data collection mode, the GPS receiver sys-

tems simultaneously collect raw data from all available satel-

lites while a receiver is moving.

In most cases, one GPS receiver is located on a known point

serving as a base station collecting data at that location for the

duration of the survey.
