用红外地平仪和太阳角计的量测信息来估计卫星姿态,其量测模型根据使用量测量的多少或组合的不同可有十几种,本文利用文献[1]中给出的冗余量测模型和能观度概念,找到了各种量测模型的精度解析式和奇点分布,并从理论上对它们进行了比较,从而解决了量测模型最优选择问题。 The satellite geostationary attitude can be estimated by using the measurement information of the infrared horizon and the solar angle meter. There are more than a dozen or so different measurement models based on the measurement of the amount of usage. In this paper, the redundancy given in [1] The model of measurement and the concept of observability, the analytical solutions of the various measurement models and the distribution of singular points were found, and the comparison was made theoretically to solve the problem of the optimal selection of measurement models.
