摘要

The article deals with accuracy evaluation of a remote sensing satellite attitude control software formation and optimisation using a satellite navigation system. The performance characteristics of the onboard navigational software, which supports functioning of the imaging equipment are considered, based on the results of the navigation system operation aboard the Resurs-DK Satellite. Also analyzed is the usage of GLONASS and GPS navigational systems with account of reduced-time possibility to receive navigational messages by the satellite antenna assemblies. Here it is demonstrated that the evaluation of the attitude control software accuracy highly depends on the accuracy of predictable and current CoG motion parameters if the problem is tackled from the point of view of imaging equipment pointing at target ground strips. Some guidelines on improvement of the control software and effective timely acquisition of checking information on ground-strip imaging accuracy are given.
