Abstract

Global Positioning System (GPS) is more and more being used in the attitude measurement, the error accumulates over time and the accuracy of the system can’t be ensured after a long time, the GPS has the performance of effective real-time and stability in accuracy through the application of the GPS measurement of attitude in resolving. After determining the attitude of carriers using measured carrier phase of GPS,solving the carrier phase ambiguitie problem, Real-time attitude determination is derived from extremely precise differential carrier phase measurements among GPS antennas mounted on the vehicle.A simple and efficient way to determine the attitude,use the GPS OEM boards,carrier phase difference method,QR decomposition algorithm.The feasibility and applicability of the design are validated through experiments.The results show that:the method can get the attitude in a short time and is of higher accurate.
