GPS卫星坐标计算程序

使用GSM传递卫星定位信息的源代码,适用于C51系列单片机.-The use of GSM transmit satellite positioning information source code, applies to C51 MCU.

Subroutine for computing an Ionospheric range correction for the GPS L1 frequency from the parameters broadcasted in the GPS  Navigation Message. 

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。

GPS全球定位系统的应用 于大家共同分享啊 好好学习啊 -GPS Global Positioning System used in the U.S. to share study hard ah ah

均匀线阵方向图形成，包含没有波束指向和30°波束指向，加切比雪夫权值（旁瓣幅度相同）-Uniform linear array pattern formation, with no beam pointing and 30 ° beam pointing, Gache Chebyshev weights (the same side-lobe amplitude)

gps基线解算基础函数，包括伪距定位，差分定位，坐标转换等

MO中利用图片生成点符号专题　 deskfee 发表于 2005-3-15 14:34:24 用truetype字体可以比较方便的实现点符号，但用图片可以实现更加漂亮的点符号（如果你认为你做的图标足够漂亮的话，^_^），只是实现起来麻烦一点。 文件是txt,下载完后请先更改-MO use photographs to generate symbols deskfee topic published in 2005-3-15 14:34:24 truetype fonts can be used to facilitate the realization of more symbolic point, but pictures can be used to achieve a more beautiful symbol of the point (if you think you have done enough beautiful icon, ^ _ ^), but is only one point up trouble.
