>If my relative velocity of 450 km / hour is right , does this compute to an >approximate orbit of 50 km or so below the geo belt? I get 3211km lower orbit. Seems extreme. I used the formula: velocity (m/s) = sqrt(3.986e14/radius(m)) Make sure you convert everything to meters and seconds If geo orbit is 42,000,000m then v=3080m/s if we change v by 125m/s (450km/h) then orbit is 3211km lower. >(I'm assuming that different topgraphy below their lots will have a marginal >affect on orbital height ) The moon has a much bigger influence than mountains of course and messes up these orbits all the time (makes them incline so they aren't over the equator anymore - they oscillate above and below). The sun too. - George Roberts ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
