Abstract Global satellite navigation system has become one of the top technical means in the world. The use of satellite navigation in many fields, such as deformation measurement, civil navigation, search resources, geodetic survey, auxiliary precision engineering monitoring and so on, can play its high precision positioning, all-weather monitoring and other technical characteristics. At the same time, satellite navigation system is combined with modern information technology. Internet technology and so on, which realizes the automatic collection, transmission, processing and analysis of safety monitoring data, and the application efficiency is maximized. The present situation and application of satellite navigation system to monitor the deformation of high-rise buildings are studied in this paper. Nowadays, more and more high-rise buildings in the world have sprung up like bamboo shoots. Therefore, how to realize the satellite navigation system to carry on the all-weather, the high precision, the high efficiency monitoring to the high-rise building, carries on the diagnosis to the dangerous signal in time, timely carries on the forecast to the future possible danger and the timely stop loss, this has the very important realistic significance. By reading the literature, the paper expounds the concepts of satellite navigation system, satellite navigation system and Internet technology in detail. The paper mainly takes the high-rise building scaffold as the object of deformation monitoring, and expounds the advantages and reliability of GPS as high-tech for deformation monitoring of high-rise buildings. Finally, through experimental design, the recognition of GPS technology by comparative method reflects the inestimable position of satellite navigation technology.

The BeiDou Satellite Navigation System of China can provide users with high precision, as well as all-weather and real-time positioning and navigation information. It can be widely used in many applications. However, new challenges appear with the expansion of the 5G communication system. To eradicate or weaken the influence of various errors in BeiDou positioning, a BeiDou satellite positioning algorithm based on GPRS technology is proposed. According to the principles of the BeiDou Satellite navigation system, the navigation and positioning data are obtained and useful information are extracted and sent to the communication network through the wireless module. The error is corrected by establishing a real-time kinematic (RTK) mathematical model, and the pseudorange is calculated by carrier phase to further eliminate the relativistic and multipath errors. Based on the results of error elimination, the BeiDou satellite positioning algorithm is improved and the positioning error is corrected. The experimental results show that the positioning accuracy and efficiency of the algorithm can meet the actual needs of real-time dynamic positioning systems.
