碩士 / 國立臺灣海洋大學 / 通訊與導航工程學系 / 99 / The paper by Kalman algorithm combines with design of ultra-tight integration navigation. Ultra-tight integration, also known as deep integration, has superb complementary nature between GPS and INS when front-end receiver receives I.Q. signals for real-time tracking. And velocity complementary is used to estimate the drift rate of auxiliary carrier Doppler ultra-tight structure, so as to enhance the performance of loop tracking.
The structure of Doppler ultra-tight compensated integration provides more accurate concept of drifting rate which is resulted from Doppler. Increasing frequency and phase lock loop are applied to the filter to enhance the internal structure of multi-path interference and high dynamic capabilities and performance when to strengthen the weak signal tracking capability, improve the urban or indoor positioning accuracy.
The feature of Interacting Multiple-model can be fully applied to the system which contains uncertainties, even to distinguish the position when in high dynamics; by the characteristics of Interacting Multiple-model algorithm to support ultra-tight EKF UKF, so that positioning is more flexibility and to enhance the accuracy of system.
