| Now multi-antenna GPS based attitude system is researched deeply, And is in a stage of project and applying research ,but single-antenna GPS based attitude system still in a preliminary stage .The fundamental principle of for synthesizing aircraft attitude information from single-antenna is presented in this paper ,and the key problem of it-kalman filter is also discussed .According to the measurement scheme described in this paper, a test machine based on DSP is designed. The measurement and control part of it is written by C language and the experimental curve is given which shows the measurement precision of this system satisfied requirement of general attitude meansurement. |
