A new method to improve GPS attitudedeterminationaccuracy in close shot target and three-dimension survey system is discussed based on the introduction of principles of GPS attitudedetermination.
To get high accuracy of satellite attitudedetermination, a new approach of satellite attitude determination system, which combines the star-sensors with gyro, is presented in the article.
Third, introduce the principle of extended Kalman filter, and analyze the layout of GPS antenna and factors which can impact the accuracy of attitudedetermination.
