Position accuracy is the critical ask of all Global Navigation Satellite Systems (GNSS), but errors like reflection, refraction, signal noise, clock errors, and multipath degrade the range computation between the satellite and the receiver. Incorrect range computation leads to errors in the receiver position. So minimizing the error in the range calculation improves the position accuracy. The differential pseudo-range technique uses two receivers, one of which is positioned at a precisely known location to compute the range error and the other receiver uses this error to improve its position accuracy. This paper explains an experiment conducted at a reference point and other five points within the range from 60 m to 120 m away from the reference point. Computing the accurate positions for those five points using the reference station is the objective of this experiment. The location of the reference point is precisely known and was measured accurately by the Survey of India (SOI). The experiment used the Indian Regional Navigation Satellite System (IRNSS/NavIC) receiver and the differential pseudo-range technique to compute the position error of the five points.
