- Abstract
ISRO is operating many communication / meteorological satellites to meet the national requirements. Number of operating satellites is growing steadily and presently nine satellites having different payload configuration and orbital characteristics are operated. Based on the communication needs and programmatic requirements, multiple satellites are collocated at different longitude slots. ISRO’s first collocation operations of communication satellites started with INSAT-2B / 2C operation from 1996 and presently three satellites are collocated at 74 deg, and another three satellites are collocated at 83 deg E longitude. The collocation strategy used by ISRO ensures minimum inter-satellite distance in all situations of orbital errors and station keeping errors. This paper describes the ISRO’s strategy, its experience and the evolution to take care of multiple satellites having different A/M ratio and communication constraints. The effectiveness of the strategy was confirmed by optically imaging the satellites.
