Hello Maged and everybody,
There is an online overview about the GPS. There is a section there
about error sources also. The site is
http://www.colorado.edu/geography/gcraft/notes/gps/gps_f.html
Regarding your recent findings in Sinai Maged, didn't we have an
exchange waypoint agreement between us?
By the way, a note for all interested GPS users. GPS is a wonderful
device, it makes you feel as if you are playing video games and the
desert is your whole screen/field, however never rely on a GPS as your
soul source of navigation in a safari. Even if you have a ton of extra
batteries with you. Maged and I learnt that lesson the hard way last
January :)
And thank you Khalid for checking my web site. It hasn't been updated
for a while. I'll work on it soon. Monirs pictures are great and I'd
very much like for all of us to share pictures related to the Sahara and
safaris. So I'll try and post some more of mine also.
Salam,
Shaadi
