the reports tell you they are broken, I do though have had other pub condensed chat which comes from a place where your pint shakes on the table every week at exactly the same time and day. But nothing that's not public domain its just straight talk without the political waffle and fluffing of the situation.
Only the latest sats which have just gone up have the short circuit fixed in the iridium clock and a changed maser clock.
Out of the 22 sats up there two are in the wrong orbit...… And sort of work but again they can't take part in the fancy stuff.
The ones that are left 3 are the test beds, IOV sats and are coming to the end of their life, and they are working perfectly but running out of fuel.
So out of that 22 there is 11 sats functioning that are mainstream and 4 in commissioning for launch . From that lot that are up there and working there is 6 which are on there second mazzer with no back up. if that one goes they are onto the iridium clocks which means the high precision signal is not possible any more.
So out of 22 there at 5 satellites which could be deemed 100% functioning fit for use with backup with a long term future.
So out 26 in orbit only the latest 4 are good. And 5 that haven't had any failures yet but still have problematic hardware. All the rest are either, end of life, out of orbit, or have no backup.
There is no work round for the short circuit. The maser work round is ground monitoring and control.
Low res went live in 2016 no date yet for the high res service. By which point the sbas system will be rolled out so the commercial market in Europe will already have other options apart from DGPS. No license still in the USA so its illegal to use even the low res signal.
A few car systems can use it and Iphones and a couple of other smart phones.
Currently the service is no different to GPS. The emergency stuff they have got working I believe with a 2 km resolution.
