    REPEATER FOR L1 / GLONASS / GALILEO / BeiDou

    The L1 / GLONASS / Galileo / BeiDou repeater unit has an effective coverage area of 35 – 40 meters diameter, when mounted at a height of 10 meters.

    The unit has a built-in antenna that radiates signal in a hemispherical pattern with 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.

    WATERPROOF (IP67) GPS L1/GLONASS/GALILEO/BEIDOU REPEATER UNIT

    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

    The repeater is usually supplied with standard (non-waterproof) AC/DC power supply if used in dry conditions. 

    An IP67 waterproof power supply is available for high-moisture environments.

    GNSS/GPS signals explained

  • Coaxial cable used in GPS repeater kits

    The cable supplied with a repeater kit is RF240 low-loss coaxial, with an overall outer diameter of 6mm.

    It is pre-cut and terminated with a TNC connector to attach to the antenna and an SMA connector to connect to the repeater.

    It is offered in lengths of 10m, 20m and 30m, which means that most “standard” requirements are covered.

    RF240 can extend to approximately 40m without any detrimental effect on signal strength or quality.

    For longer distances the cable can be upgrade to RF400, which is similar in construction to RF240 with an overall outer diameter of 10mm.

    Extend distances further by using GNSS amplifiers and GPS over fibre where necessary.

  • GPS antenna

    The antenna supplied with the L1/GLONASS/Galileo repeater kit is the Tallysman TW3742.

    The TW3742 is an active antenna with an internal low-noise amplifier (LNA) that inserts 40dB signal gain.

    The LNA boosts the received signal before it travels down the coaxial cable to the repeater input.

    A 5V DC power source for the LNA is provided by the repeater through the coaxial cable.

    The supplied universal mount and cable guide allows the antenna to be mounted on a vertical, horizontal or sloping surface.

    See the repeater installation guide for full details.

  • IP67 explained

    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”.

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

    —————————–

    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 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 meter.
