Indoor Satellite Positioning System

I&T Solution Indoor Satellite Positioning System
(REF: S-1198)
Trial Project
Solution Feature
  • Realize real time full coverage of Beidou/GPS navigation satellite signals in tunnels
  • Keep the consistency and synchronization of satellite signals inside and outside tunnels, and achieve a seamless switch between the satellite navigation and positioning systems inside and outside the tunnel
  • Compatible with general navigation tools like mobile navigation applications, car navigation terminals etc and can work on map like Google, AutoNavi, and Baidu
Trial Application and Expected Outcome
  • By installing Beidou/GPS Indoor Satellite Base Stations to achieve full coverage of satellite signals in tunnels, and deploying "Zone-based" solution to provide continuous navigation and positioning services
  • "Zone-based" solution divides the tunnel into zones every 30-50 meters subject to requirements, and install an Indoor Satellite Base Station in the center of each zone
  • Each Base Station simulates the operation of the satellites in orbit above the current location and broadcasts the simulated satellite signals for navigation devices of motorists to analyze its coordinates
  • After a vehicle enters a tunnel and receives the simulated satellite signals, the navigation device can switch to the satellite positioning state in the tunnel within 1-3 seconds
  • When the vehicle leaves the tunnel, the navigation device will relocate the satellite in orbit outside tunnel within 1-3 seconds, achieving the seamless switch of navigation
