Types Of Satellites In Space

Satellite tethers tend to be relatively cheaper than spacecraft using rocket engines depending on the objective of the mission and altitude.

Types of satellites in space.

Pisacane 2005 the molniya orbit is highly eccentric. There are many different types of satellites in the sky and they have a variety of uses from transmissions to data gathering. Low earth orbits leo leo satellites occupy a region of space from about 111 miles 180 kilometers to 1 243 miles 2 000 kilometers above earth. Russian communications satellites and the sirius radio satellites currently use this type of orbit.

As of december 2018 usa designations have been assigned to 290 space missions. 63 of current operational satellites are at a low orbit level 2000 km 6 are at medium orbit level 20000 km 20 are at the geostationary orbit level 36000 km and rest 2 at elliptic level 36000 km. It is comparable to the soviet russian kosmos designation. Satellites are a manmade construction which are launched into orbiting patterns in space.

Common types include military and civilian earth observation satellites communications satellites navigation satellites weather satellites and space telescopes. Adapted from fundamentals of space systems by vincent l. Both satellite systems have unique characteristics and produce very different products the two polar orbiting satellites in their north south orbits observe the same spot on the earth twice daily once during the daylight and once at night. Polar orbiting and geostationary.

These satellites are placed in space at different altitudes and they are facing different planets depending on the applications. Space stations and human spacecraft in orbit are also satellites. This is a list of satellites and spacecraft which have been given usa designations by the united states air force these designations have been applied to most us military satellites since 1984 and replaced the earlier ops designation. Since the 1960s more than 26 000 satellites have been launched for both military and civilian purposes.

The satellite moves in an extreme ellipse with the earth close to one edge. Satellites can operate by themselves or as part of a larger system a satellite formation or satellite constellation.
