GPS机串口通信程序,可以了吧!为什么下个东东也这么难啊(GPS machine serial communication procedures, be all right! Why so next Dongdong also难啊)

GPS跟踪器原理图，源码程序，app程序V2.03版本，需要做定位跟踪的是个非常好的源码程序哦。(GPS tracker schematics, source program, app version V2.03 program, we need to make locating and tracking program is a very good source Oh.)

GPS信号的产生程序，简单易懂，很快就可以掌握GPS信号格式及生成方法。(GPS signal generation process, simple and easy to understand, will soon be able to master GPS signal format and the generation method.)

该程序能将GPS经度和纬度坐标转化为高斯平面坐标。(The program can transform the longitude and latitude into Gauss coordinate.)

很炫的底部导航，精选ios编程学习源码，很好的参考资料。(The bottom navigation flashy, selection of learning IOS programming source code, a good reference.)

基于深圳市GPS数据和深圳市电子地图的地图匹配算法(Map matching algorithm based on Shenzhen GPS data and Shenzhen electronic map)

可以读取气象资料中的站点数据，将其插值为0.5*0.5格点数据，然后可以利用格点数据进行数据处理和画图。(Station data in meteorological data can be read and interpolated into 0.5*0.5 grid data. Lattice data can be used for data processing and drawing.)

读取并且解析GPS数据信息，经度，纬度，高程等(read and analyze GPS info，longitude，latitude，elevation and so on)

对载波相位平滑伪距的原理和数据预处理进行了探讨,给出提高其定位精度的处理方法和流程。通过 两个算例得到如下结论:对C1和P2码进行相位平滑可有效提高伪距定位精度,较长时间观测定位精度可达1 m 左右,利用精密星历改进后,平滑伪距的定位精度可达0. 5 m左右 对P1和P2码进行相位平滑对定位精度提高不 大,较长时间观测平滑前后的定位精度均可达到0. 6 m,利用精密星历改进后,精度可达0. 3 m 在动态测量后处理 中,绝大部分历元利用精密星历结合相位平滑的定位精度可达2 m。 (The principle and data preprocessing ofcarrier smoothed pseudorange are discussed and themethod which can improve the positioning accuracy and its flow are given.W ith thismethod two computation examples are made.The results show tha:t 1)the accuracy can be improved efficiently by using smoothed C1and P2pseudorange in static data processing, the accuracy can reach 1m if the time is long and can attain 0. 5m if the precise ephem- eris is taken 2)the accuracy can be boosthardly by using smoothed P1and P2pseudorange, but the accuracy can be improved from 0. 6m to 0. 3m if the time is long enough and the precise ephemeris isused 3)mostepochs can reach to the accuracy of2 m precision in kinematic positions if the smoothed code and precise ephemeris are uti- lized. )

说明：  基于串口通讯获取GPS报文数据，然后进行校验，解析，显示。多线程运行。(The data of GPS message is acquired based on serial communication, and then verified, analyzed and displayed. Multithreading.)
