Assertion: Satellite is an ideal platform for remote sensing.
Reasion: Satellite in poplar orbit can provide global coverage or continuous coverage of the fixed area in geostationary configuration.

The number of geostationary satellite needed for uninterepted global coverage is

The number of geostationary, satellite needed for uninterrupted global coverage is ……………..

A remote sensing satellite is revolving in an orbit of radius x on the equator of earth. Find the area on earth surface in which satellite can not send messsage.

A remote sensing satellite is revolving in an orbit of radius x on the equator of earth. Find the area on earth surface in which satellite can not send messsage.

A satellite is orbiting the earth of mass M in equatorial plane in a circular orbit having radius 2R and same sense of rotation as that of the Earth. Find duration of time for which a man standing on the equator will be able tosee the satellite continuously. Assume that the mans can see the satellite when it is above horizon. take Earth's angular velocity omega .

Assertion : A satellite can not be set on a stable orbit in a planet not passing through the earth's centre. Reason: For the orbital motion of satellite, the centripetal force is provided by gravitational pull of earth on satellite.
