| Abstract |
It has already been shown [1] that the problem of aiding inertial navigation systems (INS) by using information supplementing the inertial information can be solved both by estimating the INS errors from its output data and by introducing a feedback in the INS navigation algorithm. In the framework of the linear theory, it was also shown that any combination of these two schemes is information equivalent to one of them if the problem is solved as a pure estimation problem. The procedure of constructing the corresponding algorithms was described. Although the problem has been solved sufficiently completely, our meetings with the designers show that there is no clarity in its understanding. This understanding is especially important if the aiding problem is solved by using coarse sensors of source information, for example, MEMS sensors, which is actual at present.
The material presented below should be considered as an additional explantation of the previously presented materials. Here illustrative examples are especially important. |
