To use GPS satellite devices inside your building you will need a repeater system to transfer the outdoor signals to the interior.
A repeater is a device that relays GPS signals to any indoor location that isn't normally reachable.
The repeater receives GPS satellite signals via an antenna located outside the building and re-radiates them to the indoor or covered space.
We have GPS repeater kits available that come with all you need to need to bring the signal inside your facility.
For larger or more complex situations, we work with our clients to specify a custom-designed system.
So How Does This Work In Practice?
• In the first instance you need to put an antenna outside, preferably at roof level, in an area where the antenna can "see" the maximum amount of sky that's possible.
• Fix the GPS antenna securely to any vertical, horizontal or even sloping surface by use of the versatile mounting kit supplied in the kit.
• Run a coaxial cable from the antenna location to the inside of the building to the area(s) where you need the signal.
• Plug the cable into the repeater unit and power it up.
The outdoor GPS signal will be relayed from the outdoor antenna to the indoor repeater, and any GPS-enabled device within a radius of 18-20 metres will receive a signal as if it was outdoors.
Note: the repeater inside the building will relay the exact co-ordinates of the outdoor antenna to the interior of the building - it will not provide co-ordinates for the repeater unit itself.
