Wide-Area GPS Augmentation
Flight International carried a story last week (30 September - 6 October) that said the Indian government had given the green light for launching a GPS augmentation system called Gagan. "Gagan could be interoperable with the European EGNOS system and Japan's space-based augmentation system".
This seems to imply that the Japanese system (MSAS?) and EGNOS are interoperable, and because of the close aeronautical relationship between Japan & the USA, presumably the Japanese system is interoperable with the American WAAS?
If so, why aren't we using the Japanese satellite in NZ (and Australia) to provide more reliable and more accurate navigation?
Presumably we'd need at least one uplink station, but wouln't that be relatively cheap?
What proportion of the international fleet are fitted for (or with) WAAS, so would be easily able to take advantage of the technology?
Am I 'away with the faeries' on this, or what?
