Following Ofcom’s authorisation of GPS/GNSS repeaters and subsequent licencing regime, Chronos can ensure your installation is designed to, and compliant with the required EN 302 645 ETSI Standard and required practices.
Chronos is perhaps the UK’s largest installer of GPS/GNSS systems, having installed over a 1000 worldwide. From the OSNET to large numbers of mobile and fixed telecommunication sites and a number of UK military installations our teams has a unique level of experience and knowledge.
Chronos’ installation services can apply to both authorised repeating systems and to GPS antenna systems to provide GPS RF to equipment within buildings, including the use of GPS RF over fibre where necessary.
Why Install GPS Repeating Systems?
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 a plane 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, GPS repeating systems allowthe 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 workshops, 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.
