Ground station
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. Earth stations communicate with spacecraft by transmitting and receiving radio waves in the
super high frequency
or
extremely high frequency
bands
(e.g.,
microwaves
). When a ground station successfully transmits radio waves to a spacecraft (or vice versa), it establishes a
telecommunications link
. A principal telecommunications device of the ground station is the
parabolic antenna
.
