L1/L2 GPS repeater kits on sale – 25% off while stocks last

You may have noticed that the range of GPS repeater kits offered by FalTech has evolved nicely in recent months.

Our top-of-the-range repeater provides indoor coverage for four satellite services simultaneously, all in one neat enclosure measuring just 244 x 165 x 44mm.

GPS repeater with Galileo support available now (Dec 2016)

The GPS repeater product range offered by FalTech GPS has been streamlined down to three sub-categories to support all the most widely used GNSS signals:

  • GPS L1 – the most commonly used signal that is used by satnav devices the world over; available in a standard IP51 (non-waterproof) enclosure.
  • GPS L1 with GLONASS and Galileo – the GLONASS signals come from the Russian satellite constellation and are often used in smart phones, for example, to provide extra accuracy and resilience.  The Galileo system is nearing completion and will offer an alternative positioning service upon which European nations can rely.  Available in standard IP51 and waterproof IP67 versions.
  • GPS L1 with GLONASS and Galileo plus GPS L2 – the L2 signals physically come from the same satellites as the L1 signals, on a different frequency.  Most often used by civilian and military aviation organisations, as well as surveyors, who need the extra accuracy afforded by the L2 signals.  All this in one compact IP67 enclosure.

FalTech GPS showing coaxial-based Iridium repeater system at ESS 2016

FalTech will be launching a brand new coaxial-based Iridium repeater system on stand R74 at the Emergency Services Show at The NEC on 21/22 September 2016.

Here’s a bit of background to explain what the new repeater offers:

Iridium two-way satellite telephones are used all over the world. They generally can’t operate indoors, because the structure of the building blocks ingress and egress of the signal.

When it isn’t practical or safe to leave the building to use a satphone, a repeater system overcomes the barrier put up by the building and allows satellite communications up to 3Km from the outdoor antenna location by using fibre optic cables.

Coaxial Iridium repeater

Coaxial Iridium repeater – optimised for situations where a large distance between outdoor and indoor antennas isn’t necessary

An optical outdoor unit (ODU) is roof-mounted along with a pair of antennas (one for transmit and one for receive) and connects to an indoor unit (IDU) up to 3Km away via optical fibre cables. The IDU converts the optical signal back to RF and makes the signal available indoors via a pair of ceiling-mounted antennas.

However, it isn’t always necessary for the outdoor and indoor antennas to be such a long distance apart.

A coaxial Iridium repeater with two outdoor and two indoor antennas, but no optical fibre interfaces, can be used when the distance from outdoor to indoor antennas is typically less than 40 metres, for example in an aircraft hangar.

The new coaxial repeater system effectively merges the outdoor unit (ODU) and the indoor unit (IDU) into one combined repeater and removes the optical fibre interfaces.  The single IP65 repeater unit is roof-mounted and comes with two indoor antennas and two outdoor antennas, with four 10 metre coaxial cables to connect it all together. That’s all there is to it.

This is a great development in the Iridium repeater portfolio; it’s what amounts to a “Lite” version that is smaller and cheaper than its optical fibre stablemates.  Nonetheless, it provides indoor coverage where it previously wasn’t available and is simple to install.

Reliability is superb – backed up by a three year warranty from the manufacturers.”

There’s a full description within this website if you can’t get to the Emergency Services Show in September.

GPS repeater system enables use of Limmex emergency watch indoors


An elderly gentleman, living in a remote English village, was feeling a little vulnerable.

Although fit and active, he wisely (and bravely perhaps) acknowledged that he isn’t as nimble as he once was.

His house is set in a large estate, with separate workshop, garage and office facilities in adjacent buildings.
