I thought they could get height via GPS. Garmins advertising only some GPS units containing a "Barometric altimeter features", then put doubt in this. Thanks for giving a clear answer, I have learnt alot from this thread. Keep it coming ;)

At the "satellite" page, press "page" button three times to go to the "trip computer" page. In this page, press "pg up" once. It will show the "speed" information. Press "enter" to display a popup menu, press "enter" again to select "change fields" option, and again to select the "speed" field. Use "page up/page down" to move to "elevation" option. When "elevation" is highlighted, press "enter" to select it. That's it. You now have a digital display wrist altimeter.

Kris,

you can definitly download data from a 101; I am doing this for some time now.

Garmin's web site says: 'The Foretrex 101 has all the features and functionality of the Foretrex 201, including PC interface capabilities for downloading waypoints, tracks and routes, but operates on two AAA batteries.'

A GPS receiver must be locked on to the signal of at least three satellites to calculate a 2D position (latitude and longitude) and track movement. With four or more satellites in view, the receiver can determine the user's 3D position (latitude, longitude and altitude).



That's true when you're starting from scratch with zero data about where you are or what time it is. In principle, though, a GPS receiver is only likely to travel a fairly short distance between measurements. So it's possible for a GPS receiver to have a clock in it, and to have a memory of recent locations, so that it can estimate to greater precision with fewer satellites.

I'm not sure to what if any degree real-world portable receivers do this... I know that I've used GPS receivers at work for time synchronization & they take advantage of this to eke out better data.

My advice is to do what your parents did; get a job, sir. The bums will always lose. Do you hear me, Lebowski?
