Satellite ground station components.

A ground station earth station or earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft constituting part of the ground segment of the spacecraft system or reception of radio waves from astronomical radio sources ground stations may be located either on the surface of the earth or in its atmosphere. The type of equipment found at a ground station will vary depending on the type of satellite and the nature of the mission but there are similarities found in all stations. Data rates in most cases range from 4 kbit s up to 16 mbit s vsats access satellites in geosynchronous orbit or geostationary orbit to relay data from small remote earth stations terminals to other. A satellite s thermal system protects its sensitive electronic and mechanical components and maintains it in its optimum functioning temperature to ensure its continuous operation.

Geoffrey hyde pier l. The majority of vsat antennas range from 75 cm to 1 2 m. For example a spacecraft transmits its telemetry data which can contain information about its current position or state to ground stations. 07 august 2015 at 22 48 rf equipment ground station components.

Challenges and design considerations for satellite ground stations. At the earth stations that form the ground segment of space and satellite communications systems a variety of equipment is needed depending on. Know capabilities of typical dedicated ground systems and common multi user. Know components of ground station architecture 4.

A very small aperture terminal vsat is a two way satellite ground station with a dish antenna that is smaller than 3 8 meters. Ground system design col john keesee 6 17 2004 1 lesson objectives the student will. Satellite components that can be exposed to radiation are shielded with aluminium and other radiation resistant material. Satellite ground station play a critical role in a satellite network as it need to take care of recovering the informaion from received signal which is very weak and noisy after travelling path from the satellite to the earth.

Get the satellite and ground infrastructure experts on your side from day one. Ground stations consist largely of an antenna that physically communicates data from orbiting spacecraft and processes it into actionable reports for satellite and human spaceflight operators. This allows a ground station to track. In these tutorials we will look at the various component parts that make up a satellite ground station and the typical practices that engineers employ during satellite ground station engineering projects.
