I understand the next set of iridium satellites which are being launched will also have receivers for 1090MHZ ADS-B. In effect, this means every bit of Australia will be covered to ground level by ADS-B, without any additional ground stations. This would offer the potential of Class E air space at locations where there is no surveillance at the present time.
I’m only saying this because of the Australian claim that you can only have Class E where there is surveillance, of course it is different everywhere else in the world.
I suppose the key will be – what will Iridium charge to provide the ADS-B locations to a service provider such as Airservices Australia?
Here is a bit more information on it,
Aireon
It appears Airservices Australia has recently signed an MOU-type document with Aireon
