Research And Design Of Mobile Positioning System Based On GPS/Beidou

With the development of Internet and mobile communication technology,people's demand for location-based services is increasing day by day,and the accuracy requirements are also higher and higher.Satellite navigation and positioning technology also plays an important role in various fields,such as transportation management,meteorological monitoring,forest fire prevention,disaster relief and so on,which brings great convenience to people's life,especially the Beidou and GPS positioning system.It is widely used in transportation,meteorology,electronic information,forest fire prevention and other industries,as well as the location service needs of ordinary users.Therefore,mobile location technology has become a hot research topic.In order to improve the positioning accuracy and solve the problem of outdoor positioning,this paper designs a mobile positioning system to achieve accurate positioning.In real life,the single-mode positioning system often has the problem of relatively large positioning error,and when people are outdoors,it is inevitable that when the mobile phone is out of power or fails,they can not carry out real-time positioning,and obtain the current user's geographical location,especially in the emergency,it is difficult to ensure personal safety.So it is very important to locate users in real time outdoors.On this basis,this paper combined with the latest related technology to design a mobile positioning system to solve the problem of real-time positioning in the outdoor.The equipment adopts multi-channel communication,multi-mode communication and intelligent analysis of data,and is equipped with GPS/Bei Dou dual-mode positioning system,so that the equipment can receive more satellite signals and improve the positioning accuracy;At the same time,the equipment is also equipped with temperature control module to prevent the equipment from normal operation in cold environment.When the temperature of the equipment is too low,the temperature control module will increase the voltage and adjust the working power to keep the equipment running at a normal temperature;The device is also equipped with a human-computer interaction module,users can send location information to the target contact,so that users can carry out real-time positioning through the device no matter when and in what environment,so as to solve the problem of outdoor positioning.Compared with some products on the market,the mobile positioning system designed in this paper can be applied to outdoor positioning,vehicle positioning and other directions,aiming to solve the problem of receiving signals in case of emergency,such as the situation of accidents due to unable to locate in case of emergency.At the same time,it can also adjust the temperature through PID temperature control algorithm in the process of use,Make the equipment work at a relatively stable temperature,so as to reduce the situation that the temperature is too low to work.The device not only improves the accuracy of positioning,but also solves the security problem.At the same time,it reduces its own cost,so that users are no longer troubled by no signal,and real-time positioning is realized.
