DIY GPS Receiver Taps 2x As Many Satellites With Same Hardware

Andrew Holme loves to do it himself. His scratch-built GPS receiver is now able to tap twice as many GPS satellites, upping the count to 8 in total. Last year, the hardware he had built was able to tap 4 satellites, which is a minimum number needed to determine the location. Hack-A-Day reports that increasing the number of satellites won't improve the accuracy of the system, but it will eliminate the issues that may arise in case any of the satellite gets dropped because of some obstruction.

Holme has fixed bugs and improved on his design, which makes his system track location with +/- 5 meters accuracy; even when all 8 satellites are not engaged. Not bad, we'd say, for a home-made GPS system. What say?
