A filtering algorithm for high precision attitudedetermination of a specific satellite is presented based on star-sensors and fiber optic gyroscopes (FOG).
Integer ambiguity resolution is the key problem of GPS based real-time attitudedetermination system which use double differencing carrier phase observables.
GPS姿态测量通常采用双差载波相位观测量，因此整周模糊值解算成为GPS实时姿态测量的关键问题。

And the research of the GPS attitudedetermination system is to give high precision three-dimension attitude of the vehicle flat roof and the antenna's position.
