Study on Pseudo-attitude Determination Technology Based on Single-Antenna GPS Receiver

摘要

High-tech GPS plays a crucial role to the vigorous development of spatial sciences and applications, GPS attitude determination technology is an important application of GPS. However, the technology of pseudo-attitude determination based on single-antenna GPS receiver is still in its infancy stage, a large number of simulation experiments have proved the feasibility of this new method, but it is still a lack of the actual authentication. First of all, we do a general introduction to the whole structure of the attitude determination system. And then we analyze the key parts, including the kalman filter and the pseudo-attitude model. Based on this attitude model, we carry out simulations which has illustrated this new technology is very suitable for high_speed flight. Finally, a new system mainly including the high-precision SuperStar GPS receiver and PC104 computer is tested. The results have shown that the system based on single antenna had the high precision, which could meet the requirements of conventional attitude determination. Whatpsilas more , some important applications of the pseudo-attitude determination system are be simply listed in chapter six and chapter seven.
