摘要
为了使高精度GPS普及化,开发了一套成本低廉、外观小巧的高精度定位系统。不同于基于本地基站的差分定位方法,此系统可嵌入多种设备,便于携带。首先由MC110M模块先获取米级定位信息,使用嵌入式处理器STM32F105结合千寻位置的差分数据嵌入式SDK、驱动SIM7600芯片完成自动注册千寻位置差分账号、获取差分数据并转发给支持差分的GPS设备等功能,最后对获取的RTCM数据进行解算得到高精度定位。实验结果验证了系统设计的正确性,差分状态下的定位精度可达到厘米级别。
In order to popularize high-precision GPS,a kind of high-precision positioning system with low cost and small size is developed.This system is different from the differential positioning method based on local base station,it can be embedded into various devices and easy to carry.Firstly,the M level meters positioning information is achieved by the MC110M module,and then uses the embedded processor STM32F105 and Qianxun embedded SDK to drive SIM7600 chip position to achieve accounts,obtains RTCM and sends information to GPS devices which supporting differential data.Finally,calculate RTCM data to get high precision positioning.The experiment results show that the accuracy of system positioning can reach the level of centimeter,which verifies the correctness of system design.
