In the era of Internet of things, with the continuous intellectualization of logistics system and navigation system, more requirements are put forward for the design of positioning system. Aiming at the positioning requirements of high precision and high reliability, this paper proposes a low-power real-time location monitoring scheme based on NB-IoT module BC20. At the same time, it provides subscription programs and other services combined with cloud platform to realize convenient use. The experimental results show that the system realizes the low power consumption of the positioning system based on successful and accurate positioning. This achievement is of great significance to the development of low-power positioning technology in the future.
