2.4 Static survey
Static survey is a kind of positioning survey, which is mainly used to establish various control
networks.
2.4.1 Static settings
There are two ways to set up the device to work in the static mode:
1. Hi-Survey Road software – static interface – to set up the static or temporary static mode.
2. Web interface – work mode – to set up the static or temporary static mode.
Users can download the static data file to the computer, if necessary, and then use the static post-
processing software (HBC data processing software package) to process the data.
2.4.2 Static data collection steps
1. Set up the receiver on a control point with a tripod, making sure the tripod is strictly centered and
leveled. The benchmark must be installed.
2. Measure the slant height of the receiver three times in three directions, ensuring that the difference
of each measurement is less than 3mm, and then take the average value as the final height. The slant
height of the receiver is measured from the center of the measuring point to the upper part of the top
of the benchmark.
(Note: The radius of the benchmark is 0.130m, and the benchmark’s distance from the phase center of
the receiver is 0.0848m.)
