The assignment of antennas and receive chains (comprises of frequency down converter, demodulator and data ingest system) to satellite passes is an essential function at a remote sensing ground station. This task becomes complex when the large number of satellite passes are being tracked and the available antennas and receive chains are of varying nature. The problem of antenna and receive-chain assignment (also termed as just antenna assignment for simplicity) falls under the class of resource allocation problems. This paper presents the development of algorithm to assign (or allocate) antenna and receive-chain to all the scheduled satellite passes at a remote sensing satellite ground station in an optimized manner. The algorithm was developed for National Remote Sensing Centre (NRSC) ground station at Shadnagar under IMGEOS (Integrated Multi-mission Ground-segment for Earth Observation Satellites) project. The proposed algorithm is developed to resolve the above issues and provide an automated solution for optimal assignment. The algorithm follows heuristic approach and is based on the concept of dynamic priority-based allocation. The assignment task is divided into two steps. In the first step, clash analysis of the acquisition schedule is done and the passes are divided into clash groups. In the second step, assignment is done for each clash group independently. It is executed in two iterations for first and second assignment. The decision rules are different in both the iterations to provide the optimum solution. The algorithm is incorporated into Station Control Computer (SCC) software of NRSC ground station to make the process of antenna/receive-chain assignment fully automatic and is successfully made operational.
