We’ve all heard of commercial GPS devices like the Garmin or Tom Tom and even handheld devices used for Geo-Caching.Â But…Did you know you can build your own?Â A Kinematic GPS Receiver is a specialized GPS device used by engineers, topographers and land surveyors. Why? Because itâ€™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.Â This delay in signal transmission decreases the precision to serveral meters.Â Real Time Kinematic GPS receivers, however,Â use multiple receiving stations (and a base station) for pinpoint measurements.Â 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.Â Awesome stuff!Â If you want to build your own, the working plans are all available on their site.
