Types Of Satellites And Their Uses Pdf
They complete exactly one rotation per day.
Types of satellites and their uses pdf. Unlike satellites in geo that must always orbit along earth s equator leo satellites do not always have to follow a particular path around earth in the same way their plane can be tilted. This means there are more available routes for satellites in leo which is one of the reasons why leo is a very commonly used orbit. Types of satellites based on its application are. The various types of satellites include weather communication navigation satellites earth observation satellites miniaturized physics electronic devices circuits electromagnetics sat communication computer basics sitemap online test blog.
There are different types of tether satellites including skyhooks format flying tethers momentum exchange tethers and electrodynamic tethers. Satellites weigh around 2 500 kgs. Satellites can be classified based on their applications orbit in which they are placed. The geo satellites are at an altitude of 35 768 kms which orbit in equatorial plane with 0 degree inclination.
The satellites are launched with a specific objective in mind pertaining to several uses such as communications research in scientific areas forecasting the weather and intelligence. Satellites can be classified by their function since they are launched into space to do a specific job. The antennas are at fixed positions and use an uplink band of 1 634 5 1 660 5 mhz and downlink in the range of 1 530 1 559 mhz. Orbits are categorized by its altitude inclination with reference to the equatorial plane eccentricity synchronization parameters planet centered pseudo orbit and others.
Satellites can operate by themselves or as part of a larger system a satellite formation or satellite constellation. These fly at low altitudes about 160km and are used for earth observation and surveillance. The satellite must be designed specifically to fulfill its role. The type of satellite that is launched to monitor cloud patterns for a weather station will be different than a satellite launched to send television signals across canada.
These orbit directly above the equator with a period equal to one earth day. Common types include military and civilian earth observation satellites communications satellites navigation satellites weather satellites and space telescopes. Space stations and human spacecraft in orbit are also satellites.
