[Talk-GB] Sat Navs to stop working?
Yesterday, on Radio 2's drive time show, someone mentioned that sat navs would stop working next year. My wife heard it as she was driving home, but there were no details. We can't work out what they were talking about. The Listen Again page is here: http://www.bbc.co.uk/programmes/b00kg9fr I can't listen to it because I'm at work, but I can't find any mention of it on the BBC news pages. Does anyone know what they were talking about? Russ ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] Sat Navs to stop working?
My father phoned me last night to discuss it. I've not listened to the show, however my understanding is that, they satellites are gradually reducing in orbit and as such will eventually drop on our heads, as opposed to letting us know where we are. Apparently the US Military have not spent any money putting new ones up, hence the problem. Some how though, I really do doubt that it would all just stop working, the US I would have thought would need to have their own system, and I doubt they would like loosing all the money that the GPS system brings in. 2009/5/21 Russ Phillips r...@phillipsuk.org Yesterday, on Radio 2's drive time show, someone mentioned that sat navs would stop working next year.

Perhaps the hype about GPS will encourage manufacturers to start building in this capability. Glenn. ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

They are still claiming they will have 30 sats up by the end of 2013... assuming that includes the 2 test sats they have in orbit already, they are going to have to launch 28 satellites in 4.5 years. Averaging a new satellite every 2 months doesn't seem very likley in the current economic climate, sadly. - Steve xmpp:st...@nexusuk.org sip:st...@nexusuk.org http://www.nexusuk.org/ Servatis a periculum, servatis a maleficum - Whisper, Evanescence ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
