Types Of Satellites In Space

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.

Types of satellites in space.

There are two types of weather satellites. Satellite tethers tend to be relatively cheaper than spacecraft using rocket engines depending on the objective of the mission and altitude. Polar orbiting and geostationary. Since the 1960s more than 26 000 satellites have been launched for both military and civilian purposes.

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. 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. There are many different types of satellites in the sky and they have a variety of uses from transmissions to data gathering. Adapted from fundamentals of space systems by vincent l.

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. Satellites can operate by themselves or as part of a larger system a satellite formation or satellite constellation. The satellite moves in an extreme ellipse with the earth close to one edge. These satellites are placed in space at different altitudes and they are facing different planets depending on the applications.

There are different types of tether satellites including skyhooks format flying tethers momentum exchange tethers and electrodynamic tethers. Pisacane 2005 the molniya orbit is highly eccentric. Satellites moving close to the earth s surface are ideal for making observations for military purposes and for collecting weather data. Satellites are a manmade construction which are launched into orbiting patterns in space.

It is comparable to the soviet russian kosmos designation. As of december 2018 usa designations have been assigned to 290 space missions.
