Method of using theodolite’s observation data of fixed star to evaluate INS’s attitude accuracy based on time-delay compensation

Abstract In order to evaluate the attitude accuracy of TT&C’s SINS under dynamic condition, a new method using theodolite’s observation data fixed star SINS’s based on time-delay compensation is proposed. The detailed design given, and influence time delay analyzed real experiments. analysis experimental results shows that can improve computation accuracy, it valuable for engineering application evaluating conditions.
