The strap-down inertial navigation system (SINS) is widely used and becoming very important in many areas, especially in the arms industry when the GPS signal is lost or not reliable. To ensure the precision of the system, in addition to optimizing the algorithm for the strap-down inertial navigation system, the testing, and adjusting of the SINS system when installed on vehicles also play a vital role. In the article, a method of displaying SINS data on a digital map is proposed. Furthermore, the article also proposes a method to assess the influence of misalignment angles on the navigation accuracy and how to estimate and correct them.
