Sun synchronous satellite pdf merge

Finally, by merging the ideas of the multi sunsynchronous orbits and. Satellites that take pictures of the earth would work best with bright sunlight. This orbit is also useful for imaging, spy, and weather satellites, because every time that the satellite is overhead, the surface illumination angle on the planet underneath it will be nearly the same. Sun synchronous orbits for the earth solar power satellite. Sun synchronous orbits with ground tracks which reach from 50 to 80 north and south inclinations between 100 and will have altitudes lying in the range between km and 4500 km. Pdf the solar tides and the sunsynchronism of satellite.

A study was conducted to demonstrate the development of an extension of the sunsynchronous orbit, which as per definition is a finite resource similar to a geostationary orbit, the extension to the sunsynchronous orbit was considered using an undefined, nonorientationconstrained, and lowthrust propulsion system. When the satellite reaches the first strip, it counts as one orbital cycle. Geostationary orbit, geosynchronous orbits and sun synchronous orbit duration. The modis swath is 2330 km cross track and seawifs gac coverage is 1502 km cross track. The distance between successive strips is the tracking interval. Sunsynchronous satelite is that one which faces the sun every time. A 600kg spacecraft is considered in an orbit that is 571 km in altitude and at an inclination of 42. This is the total number of orbital revolutions that the satellite has to take to reach the same point with the same direction of movement. A non sunsynchronous near polar orbit would result in some days when the satellite is orbiting in a plane at 90 degrees to the direction of the sun, which would make it. A sun synchronous orbit is designed to drift slowly so as to keep in sync with the earths orbit around the sun. These concepts will be discussed briefly and then merged into a new concept call.

By definition, a given sunsynchronous orbit is a finite resource similar to a. Sunsynchronous orbits typically have nearzero eccentricity to satisfy the mission requirements of earth observation satellites. If a satellite in a sunsynchronous circular orbit was deployed at an altitude above. Pdf on sunsynchronous orbits and associated constellations. These orbits are used for satellites that need a constant amount of sunlight. Pdf multisunsynchronous mss orbits for earth observation. A sunsynchronous orbit is one that lies in a plane that maintains a fixed angle with respect to the earth sun direction. Sun synchronous orbits these orbits allows a satellite to pass over a section of the earth at the same time of day. Sunsynchronous orbiting sbsp satellite with equatorial orbiting reflector.

Due to precession, it covers another thin strip westwards, and this gradual shift continues. So a circle is the special case in which the two foci merge to. On sunsynchronous orbits and associated constellations. In other words, it combines altitude and inclination in such a way that an object on that orbit ascends or descends over any given point of the earths surface at the same local mean solar time. All this starts to get complicated when you want to plot an actual orbit. Slot architecture for separating satellites in sun. For the love of physics walter lewin may 16, 2011 duration. The space grid sunsynchronous orbiting sbsp satellites with. Hence the sso condition is primarily a relationship between the satellite s inclination and mean orbital altitude ha. Extension of the sunsynchronous orbit university of strathclyde. These satellites orbit at an altitude between 700 to 800 km. A study was conducted to demonstrate the development of an extension of the sunsynchronous orbit, which as per definition is a finite resource similar to a geostationary orbit, the extension to. A sunsynchronous orbit can place a satellite in constant sunlight, which allows the solar panels to work continuously.
