Autonomy in ground operations for geo-missions of ISRO

Geosynchronous space missions of ISRO with wide spectrum of payloads provide vital infrastructure for National Development and economic programs. Space technology had grown at a phenomenal rate and complex systems are already operational. Successful mission operations depend very much on many ground systems and knowledge base of the informed operator. An effective balance is to be maintained while using on-board autonomy and automatic operations from ground. The requirement to protect the payload services has increased since the solar activity is reportedly higher during recent times. The rich experience of Geo-mission operations has helped ISRO in formulating suitable algorithms and successfully implementing them to ensure service protection. The other benefit is operational economy since skilled work force is able to concentrate on health analysis and planning rather than routine operations. In this paper, certain case studies are discussed illustrating different levels of automation in ground operations.
