<p>The elevation angle of the satellite at the Earth station plays a crucial role in determining signal loss and delay, as well as identifying the position of a target. The Indian Regional Navigation Satellite System (IRNSS) is India’s first indigenous navigation satellite system. In this paper, the authors aim to provide the elevation angles of all the IRNSS satellites at locations in the entire coverage area (30°E–130°E and 30°S–50°N) using the traditional method. They aim to identify the satellite that provides the most accurate position at a location and the latitudinal range where all the satellites trace the maximum elevation angle. They estimated the elevation angles from knowledge of the satellites’ and the Earth stations’ latitudes and longitudes, and the orbital radius of the Earth. They validated the estimated elevation angles at a few locations in India, viz. Kanakapura, Goa, Gadanki, Kolkata, and Bhubaneswar, against those obtained from the IRNSS raw file (SAT-B L5). The two agree well. They also estimated the elevation angles for the satellites’ instantaneous positions obtained from N2YO for 2018. These also agree well with those obtained from the IRNSS raw file. The investigation reveals that the elevation angle is highest over the equator and for longitudes that are close to the launching longitudes. Across locations in India, 1&#xa0;C results in more accurate position estimation than the other satellites. A higher elevation leads to less delay, implying high accuracy in position estimation, less signal loss, and better signal quality at the receiver. The estimated elevation angles will help researchers in GPS-based remote sensing, enable the development of mobile apps for day-to-day commuting, and determine the signal loss at IRNSS channels. For effective communication and position estimation, the authors suggest using a satellite that traces the maximum elevation at a location.</p>
