A Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet's surface at the same local mean solar time. More technically, it is an orbit arranged so that it precesses through one complete revolution each year, so it always maintains the same relationship with the Sun. WebThe semi-synchronous orbit is a near-circular orbit (low eccentricity) 26,560 kilometers from the center of the Earth (about 20,200 kilometers above the surface). A satellite at this height takes 12 hours to complete … WebSun-synchronous orbit, such as Aqua’s, is designed to maintain a constant MLTAN by matching the J2 nodal rate of the satellite with the nodal rate of the mean Sun. The MLTAN is often presented in units of time with 12:00 PM – or noon – describing a Sun-synchronous orbit that places the Sun directly at zenith when the spacecraft is at the birth of a nation controversy 1915
