Earth's gravitational parameter
WebDescription The Zonal Harmonic Gravity Model block calculates the zonal harmonic representation of planetary gravity at a specific location based on planetary gravitational potential. This block provides a convenient way to describe the gravitational field of a planet outside its surface. WebThe Standard Gravitational Parameter (Earth)is the product of the gravitational constant and the mass of the body. For seceral objects in the solar system, the value of `mu` is …

WebDec 21, 2024 · The standard gravitational parameter \mu μ is expressed in SI units m³/s², but in the scientific literature and spacecraft navigation, we usually use the units of km³/s². With the above orbital speed formula, you can also estimate the satellite speed at apoapsis \small (r = r_ {\rm a}) (r = ra) and periapsis \small (r = r_ {\rm p}) (r = rp).
