DIY Real Time GPS Receiver with Incredible Accuracy

We’ve all heard of commercial GPS devices like the Garmin or Tom Tom and even handheld devices used for Geo-Caching. But…Did you know you can build your own? A Kinematic GPS Receiver is a specialized GPS device used by engineers, topographers and land surveyors. Why? Because it’s a super precise instrument which is accurate to within 1 cm.
Traditional GPS receivers have a significant delay when they receive signals from a satellite. This delay in signal transmission decreases the precision to serveral meters. Real Time Kinematic GPS receivers, however, use multiple receiving stations (and a base station) for pinpoint measurements. Good for field work but impractical when you are moving around in a speeding vehicle.
Build a DIY Kinematic GPS:
Researchers at Tokyo University think so. They created a completely open source design for precise GPS calculations. The whole GPS console using a off the shelf GPS receiver sits on a low cost Beagle board. Awesome stuff! If you want to build your own, the working plans are all available on their site.

The error you describe is caused by relativistic temporal diferences screwing up the timecode.

“Traditional GPS receivers have a significant delay when they transmit signals to a satellite.”
GPS receiver does not transmit signals to the GPS satellites. It is a receiver, it receives signal from the satellites and uses it to calculate the position.

Ah, thanks for pointing out our typo. Fixed.
