Things positioning gateway wireless communication terminals main methods: GPS positioning, Beidou, base station location, WIFI assisted positioning like. Ma Bai paper IOT gateway BMG500-A, for example, positioning highlight wireless gateway configurations different steps in the positioning mode of base station positioning and GPS, and acquire the positioning data.
Bai Ma BMG500, is a linux-based system to develop an industrial wireless gateways things , set intelligent data acquisition, multi-protocol conversion, the entire network of wireless communications, local storage and other functions. To build a common between the monitoring device and the cloud platform, intelligent things channel. Help customers PLC, various acquisition, acquisition smart sensors and other equipment, protocol conversion, wireless communication.
Widely used in electric power, transportation, environmental protection and other industries, remote data acquisition, wireless transmission, networking / Internet access, wireless Internet access, remote data monitoring, remote device management and control, remote video image acquisition and transmission functions.
A, GPS location
GPS (Global Positioning System) that is a global positioning system, is established by the United States a satellite navigation system, using the system, users can clock on a global scale, continuous, real-time three-dimensional navigation positioning and velocity; Further, using the system the user also can be performed with high accuracy and high precision time transfer precision positioning.
Features: no sim card, the network need not be connected, as long as the outdoors, accurate positioning can be substantially anywhere. But the GPS satellite search started more time, it normally takes about 2 minutes (commonly known as cold start).
Second, the Beidou
北斗卫星导航系统（BeiDou Navigation Satellite System，BDS）是中国自行研制的全球卫星导航系统。是继美国全球定位系统（GPS）、俄罗斯格洛纳斯卫星导航系统（GLONASS）、欧洲伽利略卫星导航系统（Galileo satellite navigation system）之后第四个成熟的卫星导航系统。该系统由空间段、地面段和用户段三部分组成，可在全球范围内全天候、全天时为各类用户提供高精度、高可靠定位、导航、授时服务，并具短报文通信能力，已经初步具备区域导航、定位和授时能力，定位精度10米，测速精度0.2米/秒，授时精度10纳秒。
三、基站定位
基站定位一般应用于终端用户，终端基站定位服务又叫做移动位置服务（LBS——Location Based Service），它是通过电信移动运营商的网络获取移动终端用户的位置信息（经纬度坐标），在电子地图平台的支持下，为用户提供相应服务的一种增值业务，
特点：定位条件是必须在有基站信号的位置，终端处于sim卡注册状态，而且必须收到3个基站的信号，同时定位速度快。
四、物联网网关BMG500定位配置
佰马物联网网关BMG500-A提供基于Web的管理配置界面。
如您是第一次使用，请按以下默认来配置：
IP地址：192.168.1.1
用户名：admin
密码：admin
登录佰马工业级无线网关BMG500
A.用一根网线将无线网关的 LAN口与电脑的网口连接；
B.打开浏览器，输入用户名和密码，然后按Enter键，即可登陆配置界面
C. 在您成功登录Web界面之后，您可以查看系统信息并执行配置
1）点击高级设置->GPS定位->启用GPS定位，输入服务器地址和端口号，并设置上报时间间隔，点击“保存&应用”。
2）在服务器端打开接收软件，本文档以网络调试助手为接收工具，可以看到无线网关接收到的GPS定位数据
2、无线网关实现基站定位的配置步骤
1) Click the Advanced Settings -> base station location -> Enable base station location, enter the server address and port number, and set reporting intervals, click "Save & Apply."
2) Open the receiving software in the server, the web document is received debugging assistant tool, the station can see the received positioning data received by the wireless gateway, he meant: 592A base station number, a sector is 3BD89A8, of course, If the base station is based positioning protocol developed specialized software, numerical analysis is not the same, but probably mean is this.
