Sony GPS-CS1 GPS Recorder
The Sony GPS-CS1 is a GPS recorder. That is to say it is not a satellite navigation system, it doesn't have a screen, it wont help you if you are lost. What it will do is quietly take a GPS reading every 15 seconds and record the results. You can then use the knowledge of where you were at a specific time however you like.
It is sold with software and the intention of augmenting photos (taken from a Sony Cyber-shot digital camera) with the location they were taken, but because it mounts as a USB removable drive and the GPS data is accessible in a standard format, you can do much, much more.
