Aiming at the problem of safety management of the biomedical laboratory platform, a high-precision and low power indoor and outdoor location tracking system for laboratory items was designed in this paper. The system uses Bluetooth indoor positioning, Global Positioning System and Beidou system to achieve outdoor positioning, and uses acceleration sensors to detect the displacement of items to control system power consumption, and then through the GPRS wireless communication module sends data to the database, completes positioning operation in the database and saves the data. Users can use APP to access the database, check the items location information in real time. Through experimental tests, it is proved that this system can effectively locate and track the laboratory items. [ABSTRACT FROM AUTHOR]

With the development of Global Navigation Satellite System (GNSS), the positioning technology using satellite has developed towards the direction of diversification instead of using single GPS satellite. In order to cultivate innovative spirit and improve comprehensive application abilities of students, and update and perfect the knowledge system of GNSS laboratory personnel, we put forward construction and development directions of GNSS laboratory in the new period, and designed the project construction and reform content in detail. The project emphasesed on the experiments of multi-satenite compatible integrated positioning navigation and COMPASS which is a global sateHite positioning and communication system and was independently researched, developed and operated by China. The paper discussed how to improve the technical level and professional quality of GNSS laboratory personnel in several ways, which will be of great importance for the development GNSS laboratory.
