you're welcome

I forgot to mention it, y0 is the initial altitude example: m=5x10^3 kg, y0=20x10^3 m, Ft=20x10^3 N μ=6.514x10^10 m^3/s^2, R=200x10^3 m ys = 0 m, v0 = 0m/s ÃŽâ€V=sqrt(2*6.514x10^10 * ( 1/200x10^3 - 1/220x10^3 ) ) = 243,35 m/s yb=(5x10^3 * 243,35^2)/(2 *20x10^3) = 7402 m this is only an example, you need to use the actual value of ys that is the height of the surface under the ship

Of course: use the sliders to adjust the A and R parameters or enter the values directly, the page calculates N that is the minimum number of satellites that cover the maximum surface example: I want to setup a ring of satellites in synchronous orbit around Eve so I set A to 1032847000 (from here) and R to 700000 (from here) the results are: I need 3 satellites, the distance between each will be 1601164.1 km, thei maximum distance to the surface of Eve will be 1033546.8 km this is useful expecially if you use remote tech

Have you ever wondered what is the minimum number of satellites needed to cover the maximum surface? Satellite calculator A is the orbital altitude (the orbit must be circular) R is the planet/moon radius N is the number of satellites you need D1 is the distance between each satellite D2 is the maximum distance between the satellites and the surface enjoy

v0 is the initial vertical speed [m/s] μ is the planet (moon) gravitational parameter [m3/s2] yS is the altitude of the surface [m] R is the planet (moon) radius [m] yB is the burn-start altitude [m] y0 is the initial altitude [m] m is the mass of the ship (with fuel) [Kg] FT is the max. thrust [N] all the altitudes are refered to the "sea" level the actual ÃŽâ€v needed is roughly 10% more kill the horizontal velocity, wait until the ship's altitude is equal to yB, then burn up at maximum throttle TIPS: shut down the engines and set the throttle to maximum, to start burning hit space; if during the falling the ship is slowly moving horizontally is safer to start the burn when the radar altimeter reads yB-yS.
