The structure of an aircraft hangar can block the ingress of GPS signals, making it impossible to test on-board navigation equipment without pushing the aircraft outside where it has a view of the sky.
A GPS repeater system overcomes this physical barrier by transferring the outdoor signals to the interior of the hangar, which means all maintenance work can be carried out indoors.

In a military situation, the same applies regarding the ability to carry out maintenance without leaving the safety of the hangar.
Additionally, a fighter jet would normally experience a satellite acquisition delay when exiting the hangar in a hurry – the time-to-first-fix (TTFF) could be a dangerously long period of time.
A GPS repeater ensures that fighters always have GPS lock when inside the hangar to ensure there is no satellite acquisition delay upon exit
A repeater kit for GPS L1 signals is available here.
This repeater kit provides GPS L1 with GLONASS, Galileo and Beidou signals.
The addition of an L2 signal gives a much more accurate positional fix and is widely used in military and civil aviation applications, as well as for highly-accurate geo-surveying applications.

The repeater unit has a built-in re-radiating antenna with a beam width of approximately 180 degrees, with a hemi-spherical-shaped radiation pattern.
The coverage area achieved is partly determined by the height of the repeater above the ground.
Generally – one repeater unit placed 10 meters above ground level will provide coverage within a 40-50 meters diameter.
A repeater kit comes with all you need to get indoor GPS signal in your hangar.
For larger areas where one single repeater is not enough we can offer you a custom-designed-system to meet your exact requirement.
