I suspect the southeast already has too many interrogators and that if approval were available to use the mosaic data, and it was provided economically, the total cost of the system could be reduced and improve the RF environment as well! My (limited) understanding is this is basically what happens in the US.
Farnborough do provide a fantastic service. However, if someday they get class D, I suspect the LARS service will fall by the way as 'too expensive and GA don't pay'. My vision was for how one might cost effectively provide a service tailored to the needs of GA, at a price GA can afford, rather than what CAT operators need (and not requiring the installation of TIS software)
