目前航天测量船的外测精度除了取决于无线电测量设备本身的测量精度外,还受到船体变形测量精度、船体平台的姿态测量精度等多种因素制约,针对此问题,研究并提出了一种船姿船位测量新体制——基于星/惯/卫组合的分布式船姿船位测量体制,构建了分布式船姿船位测量系统原型,推导相关数据处理模型,给出了各船载测量设备测量数据的比对方法。分布式船姿船位测量体制取消了变形测量系统,减少了1项主要误差源,提高了航天测量船的外测综合精度,并简化了船体结构设计。
At present, the accuracy of the external measurement of a spacecraft is determined by a variety of factors, such as the measurement accuracy of the radio measurement device itself, the measurement accuracy of the hull deformation and the attitude measurement accuracy of the hull platform. In response to this problem, a ship Attitude Measurement System - Based on the satellite / habit / health combination of distributed ship attitude survey system, this paper constructs the prototype of the ship attitude measurement system and derives the relevant data processing model, and gives the measurement data of each shipborne survey equipment Comparison method. The distributed ship attitude measurement system cancels the deformation measurement system, reduces one main error source, improves the overall accuracy of the external measurement of the space ship, and simplifies the hull structure design.
