| Abstract: | Ref.1] does not provide information about non ideal situation of SINS (Strap down Inertial Navigation System). Such information is still needed in China. We derived eqs.(3) through (14) to deal with non ideal situation, taking into consideration the true coning errors due to angular vibration. We further considered the quantitative errors of signals, the installation errors of gyros and the non interchangeable errors of the rigid body movements. We obtained eqs.(16), (17) and (18) as their error formulations, which can help us to reduce these three types of errors. We did computation at several different angular frequencies. The results show that our approach is effective. |
