sins algorithm and its application have made rapid development. The application of hardware simulation of strap-down navigation algorithm consumes too highly and the research phase in the laboratory is difficult to achieve, so this paper adopts computer simulation to test the algorithm. This article firstly constructed a track simulator which provides the information of the inertia device (the force and angular velocity). The data gained from the simulator is the source of sins algorithm. In this paper, a Graphical User Interface was designed .We can enter different parameters for different trajectory to test the Euler angle algorithm, direction cosine algorithm ,quaternion algorithm and rotary normal vector algorithm .This method is simple and flexible.
Attitude algorithm is an important part of sins algorithm. The calculation of attitude algorithm is used for building the mathematic platform and its accuracy of attitude algorithm can enormously affect the accuracy o...

We reduce the computational complexity of solving the main quaternionic attitude differential equation for Strap- down Inertial Navigation System (sins). Based on the analysis for the principle of custom algorithm, a complex representation is established for the quaternionic attitude differential equation. Consequently, an attitude algorithm of complex dimension 2 is introduced for a spacecraft. This new method is helpful not only to improve the efficiency of solving the quaternionic attitude differential equation, but also to perform a real-time computation.
