Satellite earth stations
A Satellite Earth Station is a type of radio equipment used to communicate with a space station (satellite) from the Earth's surface. They are typically used to provide telephony, data, backhaul, broadcast feeder links and two-way business/consume broadband or corporate type communications.
GNSS repeater equipment consists of an external antenna for the reception of the GNSS signal; an amplifier (with a restricted maximum gain), connected via cabling to a second antenna inside a building. This re-radiates the GNSS signals inside a building allowing, within a limited distance of that transmit antenna, the continued operation of GNSS receivers.
