GPS单点定位程序，卡尔曼滤波解算，matlab实现(GPS Single Point Positioning Program, Kalman Filter Solution and Matlab Implementation)

实现了基于功率倒置算法的 GPS 抗干扰实时系统，并且提出了一种低复杂度的实现算法。 运用 Xilinx 公司 的 Virtex-4 以及 TI 公司的 TMS320C6416T 硬件平台，采用双 FPGA+ 单 DSP 结构来实现整个算法。 实验结 果表明， GPS 信号经过实时抗干扰系统处理后，可以运用普通的接收机进行实时、精确的定位。该系统具有 兼容性好、精度高等优点。(Based on power inversion algorithm，a GPS real-time anti-jamming system composed of the Virtex-4 and TMS320C6416T hardware platform has been finished. In addition， an improved method which is easy to implement is also proposed. The algorithm is implemented on the architecture which is made up of double FPGA+DSP. Experimental results show that the target position which can′t be found without anti-jamming will be located precisely with ordinary receivers after the GPS signals with blanketing jamming have been passed through our real-time anti-jamming system. Lots of advantages lies in this system such as：good compatibility， accurate positioning etc.)
