WebFigure 2: With the right sideways velocity, a projectile maintains its initial height above the Earth. 3. For the reduced (one-body) problem, the general expression for orbital radius r as a function of angle θ is r(θ)= L2/µ2 GM(1 +ecosθ). (1) This is valid for any eccentricity e ≥ 0. In what follows, you should make sure that your WebLEO satellites have a circular (or elliptical) orbit at a height of 250–2000 km from the Earth surface (Figure 14.3).The orbit period, mainly depending on the altitude, varies in the range 90–120 min.As the altitude of LEO satellites is low, their velocity is very high (>25,000 km/h) and they make 12–16 Earth turns per Earth day.It means that a LEO satellite experiences …
