维纳滤波和功率倒置的比较

The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS receiver is located at a well surveyed position and its (pseudo) range measurements are compared with the actual calculated range from this receiver to the SV s. The differences between measured ranges and calculated ranges at the reference receiver are applied as corrections to the ranges measured by other receiver(s) close by.

zigzag纠错码是一种非常简单但却具有非常优秀性能的码。非常适合用于中码率或者高码率编码的系统。此为一位教授提供的源码。-zigzag error-correcting code is a very simple but has a very excellent performance of code. Very suitable for use in bit-rate or high bit-rate coding system. This is the source provided by a professor.

对于WAAS系统的最终衡量标准是可用性强调了导航系统的运行经济性。它被计算为时间的WAAS系统提供位置固定的准确性，完整性和连续性的指定级别的分数。最低运行性能标准（MOPS）的WAAS指定必须在99.99999％的概率得到满足的差分改正导航解决方案的垂直防护等级（VPL）和水平防护等级（HPL）的计算。因此，真正的误差不能超过保护水平不止一次107秒钟。如果计算出的保护水平超过了相应的警报上限则报警被丢弃的操作无法继续进行。如果操作已经开始这个条件是连续性违反和复飞，必须进行。否则系统被声明为划时代不可用。

android gps jni源码函数调用了hw_get_module加载硬件适配模块.so文件，接着通过hw_device_t接口调用open()函数，实际执行了gps/loc_api/libloc_api/gps.c定义的open_gps函数，然后调用gps_device_t接口的get_gps_interface函数，此函数也是在gps.c中定义的，最后返回HAL层中loc_eng.cpp文件的sLocEngInterface，从而打通了上层到底层的通道。
