| 1284267 | 2012-06-27 06:59:00 | In the News: Where do they get these ideas from? The GPS may track the wearer to a house, but will lose them while inside, especially if the roof is corrugated iron, and probably under tiles as well, which may have significant mineral content. I reckon most GPS systems would probably lose signal inside a house with any type of roof other than thatch! Once inside, a quick ankle-wrap with kitchen foil and the GPS can't see or be seen, so the wearer can leave and go wherever he or she fancies. If they go back home, take the foil off and go outside they will be confirmed as still being at the same premises. I doubt that they will have inertial navigation recording facilities to track those covert movements so it sounds like a pointless waste of time to me. I could be wrong though, and I hope I am!

| 1284268 | 2012-06-27 07:12:00 | Sounds logical to me. Reminds me of a while ago where they were talking about GPS tied to the vehicle speed and I wonder what happens when you go under a bridge or through a tunnel. |

| 1284269 | 2012-06-27 07:18:00 | They must use the same satellite or similar that a car GPS uses. I know that if I take my GPS out of the car and try to use it inside (I do have a corrugated roof) it will not work as it cannot receive a signal. | Bobh (5192) | ||

| 1284272 | 2012-06-27 08:02:00 | Unless of course it's also using cell towers and wifi for location information - which is likely, given it's meant to be feeding the data back somehow - and suddenly you at least have approximation data, even if it is +/- 100m instead of +/- 5m. | inphinity (7274) | ||

| 1284274 | 2012-06-27 08:14:00 | And in tunnels? :p Simply have it trigger an alert if it's out of signal for > 5minutes or something. |

In a multi story building how do you know what floor the person is on. |
