  2. 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
