摘　　要：给出了双星姿态测量的两种算法,并从几何和代数两个方面证实其存在双值问题;探讨了双值问题与精度衰减因子(DOP)之间的关系,并提出了双值问题的解决方案。In this paper,two algorithms are given for attitude determination with double geostationary satellites system, and their two solutions problem is geometrically and algebraically proved. Then, azimuthal dilution of precision and its relation with the two solutions problem are discussed. Finally, some approaches to the two solutions problem are presented.
