自旋卫星测试转台精度分析

自旋卫星测试转台用于自旋卫星控制系统的标定试验，是系统地面测试设备中的核心组成部分，其精度直接影响到系统标定试验的精度．另一方面，过高的转台精度指标将带来研制成本的大幅度增加，但有时仅对系统标定试验精度带来很小的提高，因此有必要对转台指标进行论证．根据标定试验原理，对转台引起的标定误差进行了分析计算，认为现有的精度指标能够满足标定需求，转台精度指标是合理的．

Accuracy Analysis for Spin Satellite Test Turn-Table

A turn-table is used for spin satellite calibration test, and it is a key test equipment in spin satellite control system calibration test because its accuracy can influence the test accuracy directly. On the other hand,too high turn-table accuracy will cause high cost, but improve a little calibration accuracy, so it is necessary to analyze its parameters. Based on test principle, the test error caused by the turn-table error is analyzed, and it is concluded that the turn-table accuracy can meet the test n...
