Estimation System of Exterior Ballistic Measuring Data from Space Tracking Ships

To keep abreast of the state changes of the shipborne equipments and the accuracy of the measuring data , an idea that we should build up the quality estimation system of space tracking ships’ exterior measuring data is put forward. In which many methods have been taken into consideration, such as cartography, calculus of differences, statistical analysis and comparative analysis of random errors and so on. Evaluate the working state, performance and accuracy of the shipborne exterior ballistic measuring equipment by qualitative assessments and quantitative assessments, meanwhile the accuracy of the calibration parameter is checked as well. The application of the quality estimation system is an effective way to know the problems influencing the accuracy of the calibration parameter directly like finding out the changes of the equipment state and software design flaws.
