Exploration of NavIC/GPS Receiver in both Static and Dynamic Way in an
Open Surface/Ground Area
Abstract
Indian Regional Navigation Satellite System (IRNSS)/NavIC operates in
two frequency bands namely L5 band (1176.45 MHz) and S1 band (2492.02
MHz). To navigate over vegetated area or man-made structures or
unstructured area, different methods have been used. By utilizing NavIC
user receiver along with comparison with GPS leads to accurate
navigation and near real time observation for this scenario. Various
field surveys have been conducted by keeping one receiver as base
station i.e., NavIC receiver kept constant and other receiver used as
rover receivers. These base stations depend on the exact coordinates. In
this study two fixed NavIC receivers and a rover receiver are used. By
solving the distances between fixed points, and also by using the
inverse distance weighting method, the error of rover receiver is found.
It can be implemented anywhere, therefore local navigation system can be
achieved easily.
