That does get interesting. Especially if the vehicle tracker shows it to be somewhere it shouldn't, perhaps suggesting that the driver (who would be aware of the trackers existence) was doing a bit of extra curricular work.
Been done!

It's also worth actually looking at a log of a GPS. Only the most guilty of nerd would even think about editing enough of a file like this to make yourself appear slower or in a different place.
261,726 lines to edit over the 70mile ride I plucked that from.
He didn't hack anything though. I opened my logs in an open source version of Excel! and I could have changed anything I desired (not that I need to) All he changed was the date and he had 6 months to do it.Work like this is generally not done manually line by line, that's what scripts are for. It could be a billion lines long and it would still only take a matter of seconds.
Anyway, surprised this hasn't been posted in this thread yet, this guy had the makings of a hack, but stuffed it up :P

I'm sure I've read in the past that although GPS technology is capable of centimetre grade accuracy, this is routinely reserved for military purposes, and that hardware released to the general public is purposefully "offset" or "blurred". Publicly available technology is normally only certified to 30 feet or so.
Also, GPS track files can be modified artificially, so all in all, I'd say probably not.
How many people listen to the same radio station at the same time or watch the same tv channel at the same time with any real loss of signal! Enviroment has a greater impact than the number of people receiving the same signal.It probably has more to do with how many satellites you use. More satellites = more precise fix. Perhaps you need military-grade hardware to reach satellites further away than consumer stuff can talk to, or like you say, they limit consumer stuff so that the network isn't overloaded with everyone talking to 30 satellites at once.

But then of course, how many people have access to or the know-how on scripting,then factor in type of accident. All of which will be similar but wholly different.
Yes. I figuredI was using the phrase 'hack' in the hacking something to make it work type, not trying to say he broke into a computer or something.
