Find the Delta-V Requirement for L.E.O.
Circular Orbital Velocity: Velocity due to Earth Rotation:
Vc = [ GM / (R + h) ]^1/2 Vr = w * R * cos(Latitude)
where: GM = 398603.2 km3/sec2 where: w = 7.2921152e-05 rad/sec
(Earth’s Gravitational Parameter) (Earth’s eastward rotation rate)
-
h = 200 km
-
Vc = 7.789 km/sec
-
East
-
R = 6371 km
-

-
(1) Gravity Losses
-
(2) Drag Losses
-
