  1. By way of analysis about the typical gps receiver tracking loops, the mathematical models of code multipath error and carrier phase multipath error are proposed in the dissertation ; by way of analysis about geometrical model of multipah signal, the mathematical model of differential path delay is proposed in the dissertation ; based on the above analysis, a improved carrier phase multipath mitigation algorithm using closely - spaced multiple antennas array is proposed, the result of computer simulation proves that the algorithm is feasible. the attitude parameters are often estimated using direct computation method. the relationship between the accuracy of attitude parameters and baseline length as well

    本文從經典的gps接收機跟蹤環出發,分析了多徑效應對偽距觀測量、載波相位觀測量和snr的影響,提出了碼相位多徑誤差和載波相位多徑誤差的數學模型;通過對多徑效應的幾何模型分析,提出了多徑信號相對路徑延遲的數學模型;在此基礎之上,提出了一種改進的基於窄間距多天線陣列的載波相位多徑誤差抑制演算法,通過計算機模擬證明了該演算法的有效性。
