How about highest and lowest points? (above/below sea level)

This summer, I went to Death Valley, and visited the lowest point in the Western Hemisphere (283 feet below sea level). Also, it was 120 degrees that day.

Has anyone visited the Dead Sea with their GPSr?

My low point was at sea level when I was by Seattle.

My high point was about 32,000 feet, traveling at 560 mph in a 767.

I try to stay away from places that have Dead or Death in their names.

if you took a GPSr to the Space Station?

Somewhere I have a picture of my GPSr showing over 10,000 feet while I was exploring Mt. Charleston a couple of years ago.

I should also point out that about a month before my Death Valley trip I drove over Slumgullion Pass (elev. 11,530 ft) in Colorado, which is my highest trip with the GPSr. A few years earlier, I drove over Loveland Pass (11,990 ft), but I didn't have a GPSr at that time.

I've seen my GPS reading a negative altitude in California on Highway 10 east of Palm Springs. I never took a picture of it.

The highest I've been is over 13,000 feet at the peak of Mauna Kia on the big island of Hawaii. It was quite a climb considering I started at sea level. I did take a picture of that one:

It's not certain that a civilian receiver would work well that high as certain elevation range assumptions are made in the calculation. The GPS satellites themselves are still way above the ISS, but according to a GPS article on Wikipedia, "it is illegal in the United States to track vehicles of more than 60,000 feet in altitude".

I'm not sure how the national legality of all that works as once in space, the rules are quite different. Once on the ISS, are you still "in the USA" even when you're above it? Food for thought for lawyers -- OOT I suppose.

I doubt whether the GPSr would receive a satisfactory signal inside the space station or the shuttle. All metal, radiation shielding, etc, would pretty well preclude a sat signal from reaching the unit.
