Hi Dick, Its available for everyone. It will be as global as GPS. But currently under a system test phase. Three working satellites, one of the first four has some problems. Whats the status of that one now? Two new launched in August experienced a faulty orbit injection. http://ec.europa.eu/enterprise/policies/satnav/galileo/index_en.htm Should be more usable in a year or two.

Re: [time-nuts] FYI: Galileo satellite recovered and transmitting navigation signals
Hello, One vendor we starts nimea strings with BD and GN instead of GP ie $GPGGA,blab, blab becomes $BDGGA,blab and $GNGGA,blab If all systems are selected and the receiver has enough of each system you can have up to three $*GGA messages per update.

As you enable more systems, you get more sat’s in each of the messages. For most users, there is not a lot of reason to enable multiple systems. If you want UTC sync’d to USNO you enable one system. If you want to set your watch to time from Moscow, you enable another system …. Setting your watch to both is impractical. Time-nuts will buy multiple, enable one major system on each, and compare, and draw ADEV plots!

Re: [time-nuts] FYI: Galileo satellite recovered and transmitting navigation signals
From: Hal Murray I've seen lots of comments about units that will use other than GPS satellites, but I don't think I've seen any actual output from one of them. Is that just a gap in my toy collection or has reality not caught up with the marketing hype? (Or perhaps I just haven't looked in the right place/time.) [] === Hal, The GLONASS satellites show on my Moto-G phone with the GPS Status program. They have numbers from 64 upwards. As yet I have not looked for or seen any Galileo satellites. Some recent u-blox units should see GLONASS but I don't think my LTE-Lite has a way of setting that (please tell me I'm wrong) and the recently mentioned Reyax module should also be able to do this: http://www.reyax.com/Module/GPS/RY825AI/RY825AI.pdf I've yet to power mine up.
