The strapdown inertial navigation system was placed on the indoor test bench for static test with a test time of 4500s.
1) take the first 180 data for rough alignment (analytical alignment method);
2) accurate alignment of 181s-900s data (Kalman filtering method);
3) pure inertial navigation solution is performed from 901s;
4) the positioning accuracy of the navigation system is evaluated by the method of position accuracy evaluation of the national military standard (the positioning accuracy under CEP50 and CEP95 are calculated respectively).
