DGPS only "eliminates the military advantage" as long as your DGPS transmitters are usable. DGPS transmitters can be either:
- large and hard to jam, but easy to destroy
- small, numerous, and difficult to destroy, but easy to jam
It's not accurate to say that "Some Japanese" started transmitting DGPS data and implying that this was some sort of hack, without mentioning all of the other parties (and governments) that also broadcast DGPS signals.

The military resisted for most of the 1990s, but SA was eventually turned off in 1999.
An anonymous user (218.101.54.21), with no other edits, changed this date from 1999 to 2000, does anybody have a source that can confirm the year? Should the change be reverted? Edward 09:10, 15 Sep 2004 (UTC)
