The initial alignment of the terrestrial vehicle borne strap-down inertial navigation system (SINS) is investigated. An on-the-move alignment algorithm using the information provided by an odometer, whose scale factor may have an unknown constant bias, is proposed. This algorithm is designed to take the place of the stationary-based fine alignment. The(More)
Error of inertial instruments is a very important factor which influences the accuracy of SINS. The error models of the inertial instruments are established, and then error compensation algorithms are deduced which can simultaneously compensate the installation error, error of accelerometers, dynamic error and static error of gyroscope integrated.(More)
