| Abstract: | This paper presents a new random weighting estimation method for dynamic navigation positioning.This method adopts the concept of random weighting estimation to estimate the covariance matrices of system state noises and observation noises for controlling the disturbances of singular observations and the kinematic model errors.It satisfies the practical requirements of the residual vector and innovation vector to sufficiently utilize observation information,thus weakening the disturbing effect of the kinema... |
