Orbital Period Of Polar Satellite

By the time the satellite crosses back into daylight it is over the region adjacent to the area seen in its last orbit.

Orbital period of polar satellite. As the satellites orbit the earth turns underneath. Once in daylight and once in darkness. A geostationary orbit also referred to as a geosynchronous equatorial orbit geo is a circular geosynchronous orbit 35 786 kilometres 22 236 miles above earth s equator and following the direction of earth s rotation. Once in daylight and once in darkness.

In a 24 hour period polar orbiting satellites will view most of the earth twice. In a 24 hour period polar orbiting satellites will view most of the earth twice. You can calculate the speed of a satellite around an object using the equation. Metop is a series of three polar orbiting meteorological satellites developed by the european space agency and operated by the european organization for the exploitation of meteorological satellites the satellites form the space segment component of the overall eumetsat polar system eps which in turn is the european half of the eumetsat noaa initial joint polar system ijps.

If the orbital plane of the polar satellite points at the sun now in three months time the sun s motion across the sky would make that plane perpendicular to the sun s direction. Orbit of a satellite calculator high accuracy calculation welcome guest. An object in such an orbit has an orbital period equal to the earth s rotational period one sidereal day and so to ground observers it appears motionless in a fixed. As a result a typical polar satellite moves in a circular orbit with an altitude of about 850 km and a period of 100 minutes.

The period of a satellite is the time it takes it to make one full orbit around an object. An inclined orbit whose northermost point is not the north pole but falls short by say 1000 km will be affected asymmetrically by the earth s bulge and as a. Just as the geosynchronous satellites have a sweet spot over the equator that lets them stay over one spot on earth the polar orbiting satellites have a sweet spot that allows them to stay in one time. If you know the satellite s speed and the radius at which it orbits you can figure out its period.

The satellite scans a swath about 3000 km wide on the earth s surface which is also wide enough to cover the poles despite the north south orbital inclination of 8 7.
