Application of Internet of Things Positioning System Based on LoRa System to Community Correction

With the development of Internet of Things technology, outdoor positioning technology has been investigating extensively. Based on the brief analysis and comparison of the advantages and disadvantages of various tracking systems designed for community correction targets, this paper proposes to establish a LoRa outdoor positioning system used for community correction based on TDOA algorithm with low power consumption. The experimental results show that this system can achieve a positioning accuracy of 40m (with 95% confidence coefficient). This paper analyzes and summarizes the advantages of the system which is applicable to community correction and able to meet the requirements for tracking the correction targets.
