摘　　要：A reduced-order H∞ filtering algorithm for navigation with carrier phase is presented. By taking advantage of decoupling between filtering states in a navigation solution, this algorithm reduces computational cost and is robust in colored noise. Furthermore, the estimation precision is also improved by taking ambiguities as nuisance states when the filtering process converges. Applications to kinetic simulations under different noise are presented to demonstrate robustness and efficiency of the algorithm.A reduced-order H∞ filtering algorithm for navigation with carrier phase is presented.
