About An open source physics at Singapore simulation based on codes written by Francisco Esquembre and Loo Kang WEE. more resources can be found on support URL Introduction A geostationary (Earth) satellite is a satellite that rotates around Earth in a certain orbit such that it is always positioned above the same point on the Earth s surface. Hence from the point of view of an observer standing at that point, the geostationary satellite appears to be always stationary above him/her (but actually, both observer and satellite are rotating at the same angular speed). In order for a satellite to be moving in such a geostationary orbit, there are certain conditions to meet: placed vertically above the equator same directional sense as the rotation of the Earth (determine through axis of rotation) same orbital period of Planet, in our case, Earth, thus the orbital period of approximately 24 hrs The simulation has a Earth and a Satellite object Menu Drop Down Allows for selecting what motion of Satellite is simulated. Geostationary near Singapore Geostationary near Africa Geostationary near America Non-geostationary due to direction circular motion r=3*Re, T =7.30 hr circular motion r=10.5*Re, T = 48 hr Non-Geostationary generally Unlikely Orbits Options added are: Show:equator Plane, for visualising the Earth's rotating equator plane Geo stationary, for visualising a geostationary object (RED) for comparative observation with the other modes.
