GPS repeater for L1/GLONASS/Galileo

The L1/GLONASS/Galileo/Beidou GNSS/GPS repeater unit has an effective coverage area of approximately 40 – 50 metres radius from the centre when mounted at a height of 10 metres.

The GPS repeater unit has a built-in antenna that radiates signal in a hemispherical-shaped pattern within a ~180 degree angle of view.

Using the four moulded lugs, it can be mounted horizontally, for example on a ceiling, or vertically on a wall.

All that is required is good line-of-sight between the repeater unit and the receiving devices.

The external antenna feeder cable connects to an SMA socket; the repeater sends 5V DC through the coaxial cable to power the low noise amplifier (LNA) in the antenna.

If a larger area of coverage is required, additional repeaters can be added – all using a single outdoor antenna – by use of a GPS signal splitter and/or a line amplifier.
