A leveling instrument is positioned midway concerning a point at which the bottom elevation is known (position A) and some extent whose elevation would be to be measured (B). The height in the instrument previously mentioned the datum elevation is Hello. The surveyor initial reads a backsight measurement (BS) off of a leveling rod held by his trusty assistant about the benchmark in a.

In static GPS positioning, two or even more receivers measure their positions from fastened areas about intervals of 30 minutes to two hours. The receivers may be positioned as much as three hundred km aside. Only dual frequency, copyright stage differential receivers capable of measuring the distinctions in time of arrival in the civilian GPS signal (L1) along with the encrypted army sign (L2) are appropriate for this sort of higher-accuracy static positioning.
