[0002] Positioning systems have strong military applications and broad civilian prospects. Many countries and international organizations have vigorously carried out research in this area. Internationally, many developed countries have conducted extensive research and exploration on positioning systems in the field of industrial safety. Domestically, with the increasing pace of global industrialization, the demand for personnel life safety protection and accurate location information management has shown a significant growth trend, especially in the field of hazardous chemicals production, petrochemical industry and mine tunnel construction and other high-risk environments. The importance of personnel safety and location information management is undoubtedly prominent. They play a vital role in protecting personnel life safety and preventing accidents.

[0003] However, it is not difficult to find in the application that: in areas and time periods with good observation conditions, a single system or the existing combination of multiple systems can already achieve normal positioning, ranging and timing requirements.
