A GPS Doppler model was constructed by using geometric scalar analytic approach, considering the fact that observer is not necessarily on the ground trace of the satellite. In addition to the modeling and computation of orbital angular velocity, visible window of satellite, and the maximum elevation earth-centered angle, Doppler's characterization with regard to the observing time was deduced and analyzed.

采用几何标量分析方法，建立了地心地固坐标系中GPS信号多普勒频移分析模型，计算了卫星可见地心角、卫星轨道角速度和卫星可见区间，推导并分析了多普勒频移关于接收机最大可见仰角、卫星轨道角速度和卫星可见时刻开始所经历的时间等参数的变化规律。

Based on the limitations of OBB, this thesis proposes an optimizing overlap test algorithm of bounding box and primitive. This method eliminates the bounding boxes of leaf nodes and streamlines the OBB hierarchical layer. This method also introduces a separating axis theory in the overlapping test between the primitives in order to accelerate the velocity.

针对基于OBB碰撞检测算法存在的缺陷，研究利用包围盒与基本几何元素相交测试的优化方法，消除叶子结点包围盒，精简OBB层次结构；同时在基本几何元素相交测试中引入类似分离轴的方法，加快检测速度。
