  2. Ground segment - Wikipedia

    en.wikipedia.org/wiki/Ground_segment

    Ground station equipment may be monitored and controlled remotely. There are often backup stations from which radio contact can be maintained if there is a problem at the primary ground station which renders it unable to operate, such as a natural disaster. Such contingencies are considered in a Continuity of Operations plan.

    A 2.5 m parabolic dish antenna for bidirectional satellite Internet access. A very-small-aperture terminal (VSAT) [1] is a two-way satellite ground station with a dish antenna that is smaller than 3.8 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Bit rates, in most cases, range from 4 kbit/s to 16 Mbit/s.

Ship earth station (also: ship earth radio station) is – according to Article 1.78 of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) [1] – defined as "A mobile earth station in the maritime mobile-satellite service located on board ship."

  8. Satellite ground track - Wikipedia

    en.wikipedia.org/wiki/Satellite_ground_track

    A satellite ground track may be thought of as a path along the Earth's surface that traces the movement of an imaginary line between the satellite and the center of the Earth. In other words, the ground track is the set of points at which the satellite will pass directly overhead, or cross the zenith, in the frame of reference of a ground observer.
