在DSP中实现基于帧间差分后二值图像的跟踪加框处理，原理是计算出目标（灰度为255）重心坐标后，对其进行加框处理。-In the DSP-based frame difference in the binary image of the track after the framing treatment, the principle is to calculate the target (gray 255) the center of gravity coordinates, its frami

1. 根据glonass的卫星星历计算指定时刻卫星的位置、速度 2. 将glonass系统的PZ90坐标转换WGS84坐标-1 According glonass satellite ephemeris calculations given moment the satellite' s position, speed 2. Glonass system PZ90 will coordinate conversion WGS84 coordinates

ccs3.3的坐标转换程序，封装成lib库，可以直接调入使用，WGS84转换为大地坐标系以及大地坐标系转换为空间直角坐标系，并且可以计算俯仰角。-ccs3.3 coordinate conversion program, packaged into a lib library can be directly transferred to use, WGS84 converted to geodetic coordinates and space geodetic coordinate syste
