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。

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.
