Description On a stationary GPS without a differential correction signal, you should see a 20m average radius "drunken walk" pattern. On the same receiver with DGPS corrections and a good view of the sky, the error should be reduced to approximately 2m average radius. If you've always wanted to know exactly where your house is located without that annoying GPS "wander," but didn't want to spend the money for a DGPS radio, here is your big chance! I'd like to announce a fun DGPS hack. I've written a small Un*x server and client for redistributing DGPS correction signals over the Net. Basically the server grabs the serial byte stream from my DGPS radio and sends it off over a TCP connection. The client does the same thing but in reverse. The result is that you can receive the local DGPS corrections from absolutely anywhere by using the Internet as the world's largest extension cord. You'll still need to be within 1000 miles or so of San Francisco, California, USA for best results. However chances are better than not that the GPS error will still be reduced if you are 2000 to 3000 miles away. Several respondents from 2000 miles away have noted that the remote differential signals have diminished the SA induced position and velocity errors by approximately 3x. |
