On the same\nreceiver with DGPS corrections and a good view of the sky, \nthe error should be reduced to approximately 2m average\nradius. If you've always wanted to know exactly where your house\nis located without that annoying GPS \"wander,\" but didn't want to\nspend the money for a DGPS radio, here is your big chance!\n\nI'd like to announce a fun DGPS hack. I've written a small Un*x\nserver and client for redistributing DGPS correction signals over\nthe Net. Basically the server grabs the serial byte stream from my\nDGPS radio and sends it off over a TCP connection. The client does\nthe same thing but in reverse.  The result is that you can receive\nthe local DGPS corrections from absolutely anywhere by using the\nInternet as the world's largest extension cord. You'll still  need\nto be within 1000 miles or so of San Francisco, California, USA\nfor best results. However chances are better than not that the GPS\nerror will still be reduced if you are 2000 to 3000 miles away.\nSeveral respondents from 2000 miles away have noted that the remote\ndifferential signals have diminished the SA induced position and\nvelocity errors by approximately 3x.\n","package_architecture":"amd64","stem":"dgpsip","readme":null,"dependencies":[],"reverse_dependencies":{"count":0,"url":null},"categories":["astro"],"flavors":[],"only_for_architectures":[],"not_for_architectures":[]}}
