Differential Global Positioning Systems (DGPS)

DGPS is satellite-based navigation system. The principle is getting the signals from the satellites by a receiver and converting them into coordinate and elevation data. GPS provides reliable location and time information in all weather conditions and at all times and anywhere on or near the Earth.

It increases the accuracy in large scale projects and lessens the time consumed to do the survey works. The instrument can operate even kilometers far from the benchmark without compromising on the accuracy which makes it the most preferred survey technology.

COMPASS uses the Leica GPS instruments which are known for their reliability and accuracy. All GPS instruments are calibrated by the authorized dealer periodically and are certificated.

COMPASS has the intrinsic certificates as well which are proof that the equipment’s are safe to use inside oilfields and plants. This document is required by the authorities in oilfield for all battery-operated instruments.
