And with Ken Ernandes' VEC2TLE you can do it three ways: Find velocities (and position, in three directions) from any orbit at any given time. Find the orbit from given position and velocities. Find the orbit from an initial orbit and velocity change. (Use i=0, RAAN=0 and AOP=0 to make working with absolute velocities and perigee/apogee easier) -- b_gimle@algonet.se (home) http://www.algonet.se/~b_gimle -- > > Obviously for a satellite to be geostationary it's speed decreases as it's > > altitude decreases, which will cause crash and burn at altitudes less than > > 22,300 miles (13640km). > > Among the features of the prediction program, MrOrbit, you get apparent > and actual speed at any point in the orbit.
