The L1 / GLONASS / Galileo / BeiDou 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 unit has a built-in antenna that radiates signal in a hemispherical 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.

For environments where moisture and/or dust ingress is a problem, this IP67 version of the L1/GLONASS/Galileo repeater is ideal.

The repeater specification is exactly the same as the standard (IP51) unit shown above, the only differences are as follows:

GPS repeater in waterproof (IP67) enclosure

  • Size: 200 x 89 x39mm
  • Weight: 274g
  • Input connector: TNC-socket
  • Ingress protection: IP67

As standard the repeater is supplied with standard (non-waterproof) AC/DC power supply if used in dry conditions; an IP67 waterproof version is available for high-moisture environments.

Power supply options

The IP Code, known as the International Protection Marking, IEC standard 60529 (sometimes interpreted as Ingress Protection Marking) classifies and rates the degree of protection provided against the intrusion of solid particles (including body parts such as hands and fingers), and water by mechanical casings and electrical enclosures.

For example, IP67 is usually spoken as “I P sixty seven”.

In fact the two numbers represent the two aspects of the IP rating code, so strictly speaking should be said as “I P six seven”.


For the non-waterproof IP51 devices:

The first digit 5 means that ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment.

The second digit 1 states that dripping water (vertically falling drops) shall have no harmful effect on the device when mounted in an upright position onto a turntable and rotated at 1 RPM.


For the waterproof IP67 devices:

The first digit indicates the extent of solid particle protection and the second digit indicates the level of protection against harmful liquid ingress protection.

The first digit 6 indicates that the enclosure is dust tight – it will not allow any ingress of dust.

The second digit 7 indicates that the enclosure can be immersed in liquid to a depth of 1 metre.
