Navigation satellites were developed in the 1950s and they rely on the doppler effect to calculate the position of vessels emitting a radio signal. Recovery satellites are mainly used to recover bio reconnaissance and other satellites back to earth.

Reconnaissance satellites are used to spy on other countries. Miniaturized satellites are satellites of unusually low weights and small sizes. Communications satellites anik e. 41 no transcript 42 miniaturized satellites.

They provide intelligence information on the military activities of foreign countries. Astronomy satellites hubble space telescope. Active satellites are complicated structures having a processing equipment called transponder which is very vital for functioning of the satellite. Micro satellite below 100 kg 3 nanosatellite below 10 kg.

Satellites typically use geosynchronous orbits molniya orbits or low earth orbits. Navigation satellites are also widely used by the military. Miniaturized satellites are of 3 types. Reconaissance or spy satellites e g.

Up link frequency is the frequency at which ground station is communicating with satellite the satellite transponder converts the signal and sends it down to the second earth station. Solar power space based satellites gather energy from the sun and transmit it to earth for consumption. But spherical balloon with metal coated plastic serve as artificial satellites. These satellites can even detect missile launches or nuclear explosions.

Navigation satellites navstar. The two stations can use a satellite as a relay station for their communication one earth station transmits the signals to the satellite. You can click either on the picture or on the name to learn more about that type of satellite and its example.
