  1. Its main contributions include the following several aspects : firstly, the dissertation constructs the mathematic model of short baseline orientation determination using two geostationary satellites and analyses the applicable conditions of carrier phase interferometry. orientation determination precision is analysed in depth through both the conventional linearized method and monte - carlo computer simulation method, and the mathematical simulation results show that the linearized method has the shortcoming of fairly low elevation error analysis precision in high latitude area so as not to be very appropriate there. by analyzing the definite factors influencing orientation precision, the dissertation develops the concept of orientation dilution of precision, which uncovers the internal cause of exotic error behavior of bi - satellite orientation, and has important guiding significance for practical engineering applications

    本文系統地研究了基於「北斗一號」衛星載波相位干涉測量原理實現地球靜止雙星定的相關技術,主要研究成果包括以下幾方面:首先,建立了利用兩顆地球靜止軌道衛星進行短基的數學模型,分析了載波相位干涉測量的適用件;採用傳統的性化解析法及蒙特卡洛隨機模擬法兩種途徑對雙星定的精度進行了詳分析,數學模擬結果表明在高度地區性化解析法由於俯仰角誤差分析精度略有下降而不太適合;在分析定精度確定性影響因素的基礎上,提出了雙星定精度衰減因子odop的概念,揭示了雙星定誤差特殊表現的內部機理,對實際工程應用具有重要的指導意義。
