What I think has happened is our beloved GPS receiver manufacturers have neglected to build a frequency filter into the GPS receivers they have been selling. Their decision gave them an edge in the past because not only was skipping the filter cheaper, but it grabbed more stray signal. Since GPS satellites are obviously solar powered only, and are far away, their signal is weak even on a good day. However it's like a cheap TV that blends channels 97,98, and 99 into one picture in an attempt to get the weak channel 98.... great idea as long as channel 97 and 99 never start broadcasting. And now we have LightSquared.
So LightSquared is not trying to do anything dumb, but it will be very expensive for many thousands (or more) high-precision GPS users to throw away their units and buy new ones with filters. And new ones with filters will not work better than what we have today. It would be very smart of a company that wants a good reputation with it's future potential customers to just be nice and move farther away from GPS frequencies. | |
