| With the further development of GPS technology at recent years, the method of through using of GPS carrier signal to achieve the attitude has become a new area of GPS applications. This paper around the theme of through using of carrier phase differential GPS technology to determine the three-dimensional attitude of vector. Focuses on the principles of GPS attitude measurement and algorithm, and simulation to achieve a set of attitude determination system.At first, this paper described the composition and the principle and methods of GPS location, from the three components to the signal components in the GPS system, and then to the principles and methods, all are described in detail.Then we make a description in detail and précising mathematical deduce at the principles of attitude determination and the solution of ambiguity. We mainly described three components in the principle of attitude determination: the definition of attitude angle and the axes, and the rotation of axes. In the introduction of ambiguity, this paper summarizes the currently various methods of ambiguity at first, and then introduced the LAMBDA method which has the best precision in ambiguity solution at current, and make a detail describe and rigorous deduce to the method. We also study and discuss on a variety of error which affect the precision of the system, and propose a preliminary solution.Then after understanding the theory and method, We programmed to the algorithm of which using differential carrier phase to determination the three-dimensional attitude, and also design a complete set of attitude determination simulation system, and present various key date and rigorous mathematical formula at every aspects in attitude determination, which gives a detail plan about how to build a set of attitude determination system, and simulate to prove its validity and reliability.Finally we make the summarized of the hole text and proposed to the next studied and the next problem to solve...
