In the star tracker/accelerometer inertial navigation system, the star tracker will be used to calculate the attitude matrix. The accelerometer is analyzed and integral utilizing the attitude matrix, to get the velocities and position of carrier, the feedback is formative. After star tracker/accelerometer inertial navigation system in theory is resolved,(More)
To improve the positioning accuracy in indoor environments, we use the Inertial Navigation System (INS) algorithm to perform the pedestrian tracking, and the measurements consist of two parts: the velocity error and the heading error. The velocity error can be gotten from the navigation result. Meanwhile, we get the heading error in two ways. First, taking(More)
