Digital TV base station can help indoor GPS positioning
The advantage of GSP satellite positioning is that the user's geographic location can be quickly obtained, but the disadvantage is also obvious. In the indoor environment, because the GPS signal cannot penetrate, the user cannot obtain GPS positioning data.
Rosum recently conducted research on digital TV base station technology, thereby obtaining a technology that can use the digital TV base station technology for roadbed GPS positioning or GPS assistant. Their goal is to help GPS devices obtain global positioning data in indoor environments.
Because TV signals are much stronger than GPS signals, they can penetrate walls. By embedding the time code for the TV signal, you can get the user's location. In addition, digital TV base stations need to add a GPS receiver and a 30-foot diameter GPS antenna.
At present, in addition to GPS, other positioning technologies that can be used include mobile phone base station positioning and WiFi positioning. Rosum believes that TV base station positioning can exist as a supplement to mobile phone base station positioning. The positioning data of mobile phone base stations is about 150 meters. Based on Rosum technology, you can Accurate positioning data to about 40-50 meters. The disadvantage of WiFi positioning is that it cannot penetrate certain environments.
