| Abstract: | To enhance the accuracy of processing of the data measured by space instrumentation ships, dynamic data modeling technology and wavelet transform are introduced. The random error and hull error are successfully separated, and hull error is analyzed and interpreted. Experiment shows that the aeeuraey and effeetiveness of the proposed approaeh makes it a powerful tool in data processing for spaee instrumentation ships. |
