New Speed Cameras Catch You From Space 351 351

A new kind of speed camera that uses satellites to measure average speed over long distances is being tested in Britain. The "Speedspike" system combines plate reading technology with a global positioning satellite receiver to calculate average speed between any two points in the area being monitored. From the article: "Details of the trials are contained in a House of Commons report. The company said in its evidence that the cameras enabled 'number plate capture in all weather conditions, 24 hours a day.' It also referred to the system's 'low cost' and ease of installation." I can't wait to see the episode of MythBusters where they try to avoid getting a speeding ticket from a satellite.

This has already been around for a few years.

http://www.placeengine.com/en - developed in Japan. I tried it out when they first launched it. It works quite well. Most of the major Japanese cities are covered and they have a pretty good handle on major cities outside Japan. London, NYC, LA, Toronto etc.

And yes, it can estimnate your location inside buildings as well. Of course it needs somebody to go visit those places to feed it the relevant WiFi signal strengths in the first place.
