Earth's gravitational parameter
WebThe current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM). The standard is published and maintained by the United States National Geospatial-Intelligence Agency. [1] History [ edit] WebFor example, since the earth is nearly 20 orders of magnitude more massive than the largest conceivable artificial satellite, the center of mass of the two-body system lies at the center of the earth, and the constant μ in Eq. (2.21) becomes The value of the earth’s gravitational parameter to be used throughout this book is found in Table A.2,

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).
