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
