Yep.  The "civilian channel" on GPS was a gift to everyone from the US Department of Defense, I suppose they could turn it off if they so wish, but it is so ingrained in today's culture that they won't.  Years ago, the channel was purposely perturbed to limit the horizontal accuracy to

Re: [Elecraft] OT: 3Y0Z Bouvet Island DXpedition

The elevation changes seen with civilian GPS are the result of two fairly fundamental issues: 1.  A GPS receiver doesn't really "know" where actual sea level is, it uses a mathematical model.  Since the earth is ellipsoidal-ish rather than spherical on a large scale, and since there are

The elevation discrepancies are normal - I see the same effect whendriving around down here in South Florida, randomly dropping to 10-20feet below sea level. The civilian GPS systems are not configured forextreme elevation accuracy, particularly when close to sea level. The main web site's
