Orbit ground track equation
Webp= planet radius, km (6380km for earth) H’= orbital altitude, km g s= acceleration due to gravity (9.81m/s2) 12 Orbital Period for AVHRR •T 0=2π(6380+833)√[(6380+833)/(0.0098*63 802)] •T 0 = 6091.1sec •T 0= 1.7hr • Therefore, The AVHRR orbits earth ~14.1 times per day. Comparison of Satellite Sampling Resolutions WebAero 3310 - Taheri 10 Ground Tracks The projection of a satellite’s orbit onto the Earth’s surface (or the surface of the planet around which the spacecraft is revolving) is called its ground track. At a given instant, one can imagine a radial line drawn outward from the center of the Earth to the satellite.

WebIn polar coordinates, the orbit equation can be written as [1] where is the separation distance between the two bodies and is the angle that makes with the axis of periapsis (also called the true anomaly ). The parameter is the angular momentum of the orbiting body about the central body, and is equal to WebThe orbit is synchronous if Q=l. If Q=2, as in the Global Positioning System, each satellite makes two complete orbits in one sidereal day. A satellite with Q=14/3 would repeat its ground track - the trace of points on the earth's surface directly below the satellite - every 3 sidereal days, after fourteen revolutions. The ground track of a ...
