摘要
提出一种新的双星定姿方法，即利用２颗地球同步卫星载波信号测定运动载体的姿态．文中就双星定姿原理及精度进行了深入探讨．计算机仿真试验表明，当载波相位单差观测值均方差为０．０２周、天线阵列为１ｍ×１ｍ时，双星定姿均方差可达偏航０．２３°、俯仰０．１８°、滚动０．
A new method of attitude determination using two satellites is presented inthis paper, that is to determine vehicle's attitude using carrier phase of two earthsynchronous satellites. The principle and the precision of attitude determinationusing two satellites are discussed in detail in this paper. Computer simulation statethat the mean square error of attitude determination using two satellites can be0.23° in yaw, 0.18° in pitch and 0.15° in rolling, under conditions of mean squareerror of carrier phase single difference be 0.02 cycle, antennas be 1 meter apart, andso on.
