Abstract: | An algorithm based on the error equations of inertial navigation systems is proposed to estimate the random components of errors for laser gyroscopes. The estimation is performed using the navigation parameters of an inertial system or using the output signals of laser gyroscopes. In the second case, the proposed algorithm is a low-pass filter. Its frequency analysis is compared with other filters. |
