Where a GPS navigation system is fitted in to a system or product, even if it is only a back-up, it has to be tested, maintained and calibrated in order to ensure full functionality. For example, when an aircraft is serviced or stored in a hangar, it does not have a clear view of the sky and as GPS signals are inherently low strength, repeating systems allow the GPS signal to be received inside the hangar enabling flight navigation systems to be tested in a safe/covert environment.  It can also enable a plane to have a lock on the GPS satellite before it leaves the hangar, which is important if a plane has to be airborne within minutes.

For other applications such as training facilities, workshops, test laboratories or production lines,  if used in an authorised way, GPS repeating can enable efficiencies in working practice and a significant cost saving over specialised test equipment.

The GPS signal can be repeated (or re-radiated) using variable gain controlled or “SMART” amplifiers to anywhere in the hangar/building/workshop so that even quite large indoor spaces or shadowed areas can receive the signal.  For large areas or multiple room scenarios, a combination of GPS splitters can be used to provide total coverage using a single external GPS antenna.

Applications

Live GPS / GNSS Signals brought inside your Aircraft Hangar

All navigation systems fitted in aircraft have to be tested on a regular basis.  Where GPS is fitted, even if only as a back-up, it too has to be calibrated in order to ensure full functionality.  When a plane is serviced or housed in a hangar, it does not have a clear view of the sky and as GPS signals are inherently low strength, GPS repeating systems allow the GPS signal to be received inside the hangar.

GPS Repeaters for Emergency Services

Chronos offers solutions to bring the GPS signal inside fire & rescue stations, police garages, or rescue helicopter hangars, ensuring vehicles have a lock on the GPS signal whilst inside and importantly when exiting  to respond to emergencies.  More»

Testing GPS inside a Hangar

A key task of a MRO team was to perform flight verification checks with an active GPS Signal. Planes had to be towed outside, as there was no active GPS signal available inside any of the hangars. In order to tow a plane outside, it was common practice to stop work on other planes and move them out of the way of the hangar doors. It would take approximately one hour to move a plane outdoors, perform system checks and move back into the hangar… More»
