| Abstract: | A new method to improve GPS attitude determination accuracy in close shot target and three-dimension survey system is discussed based on the introduction of principles of GPS attitude determination.The method using fixture interval of the antennas as the constraint condition is adopted to increase the baseline vectors' accuracy.As a result of experiment,the method is effective to improve the accuracy of the attitude. |
