| Abstract: | In the light of the characteristics that the signal of GPS satellites is easily losing lock under the condition of high dynamic or low signal-to-noise ratio, this paper analyzes the principle of GPS receivers with the assistance of INS and its influence on anti-jamming capability of receivers according to the characteristics of tracking loop of PN code-carrier of GPS receivers. Under the condition of intricate electromagnetic environment, INS assisted GPS receiver is the future developing direction of integrated navigation, especially the integrated mode of close coupling INS/GPS. |
