Abstract

This paper deals with the study of availability of IRNSS satellites in the space segment over its coverage area from the user location (SET-JU Campus). The objective of this paper is to analyze the visibility gap of the IRNSS satellites with respect to a user position to show that twenty four bar seven there is no interruption in service provided by the IRNSS satellites over Indian geo-graphical boundary. All seven satellites are observed over a period of twenty four hours and are mapped in terms of distance, speed, angle with respect to time. By using two line element file of the satellites in Satellite Tool Kit software the visibility gap, elevation of the satellites are mapped.
