You need an extra chip in your gps to receive the locata signal as it operates on the 2.4Ghz band. I guess they are hoping that it will become a "standard" and all new gps's will be sold with this chip.
Hopefully what happens is that there does become an actual standard for ground based GPS augmentation signals. _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
