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 stillb e reduced if you are 2000 to 3000 miles away. +Several respondents from 2000 miles away have noted that the remote +differenential signals have diminished the SA induced position and +velocity errors by approximately 3x. diff --git a/astro/dgpsip/pkg-plist b/astro/dgpsip/pkg-plist new file mode 100644 index 000000000000..b57e96fd017f --- /dev/null +++ b/astro/dgpsip/pkg-plist @@ -0,0 +1,2 @@ +bin/dgpsip +man/man1/dgpsip.1 |
