sorry to interrupt all the fun talk on here with some information, but for those that want to know why CAN TV would be interested in the FOLO system here is some info:
TV-GPS, a system that combines television signals with global positioning satellite (GPS) technology for tracking assets or people right to places where GPS alone can't go, such as in the high-rise “canyons” of urban centers and even inside buildings and garages. Especially for P&D operations and fleets that transport hazardous or high-value cargo within municipal areas, this could be welcome news indeed.
GPS, which receives signals from satellites, works very well anyplace where there is an open view of the sky. It has limitations and vulnerabilities, though. It does not work indoors, for instance, or in cities where tall buildings create canyons. It is also vulnerable to jamming or spoofing, in other words to deliberate interference. That is why President Bush has called for a back-up system for GPS and why we are preparing to introduce TV-GPS for commercial and military applications.
Television signals are the strongest precisely where GPS is the weakest, so it is a nearly perfect tracking technology pairing, As a result, the technique requires no changes to television broadcast stations yet still offers a power advantage over GPS signals and substantially superior geometry for triangulating lateral position.
Since such a wide range of VHF and UHF frequencies have been allocated to television stations, there is also a lot of redundancy built into the system and the synchronization TV signals are not affected by the ionospheric or Doppler effects that can interfere with the performance of GPS, Because they are such low-frequency signals, they can also penetrate buildings.
If TV-GPS lives up to its potential, it will enable fleets and shippers to take their coverage area that “last mile,” right down the alleyway and inside the parking garage or warehouse. It will also enable companies to expand the list of things they can track to packages or even people, and make it tougher for would-be thieves to hide stolen trucks or trailers.
