Blue Quadrant Limited

Blue Quadrant is a world leading navigational aids integrator.

We supply, install and commission navaids from the world's leading manufacturers of these safety critical systems, including CAT Ӏ, CAT ӀӀ and CAT ӀӀӀ ILS, DVORs, DMEs and NDBs worldwide.

We can provide a whole package of tools to assist airports with aerodrome safeguarding, the design and preparation of instrument approach procedures, studies for the definition of equipment specification, system design - complemented where necessary by sophisticated computer modelling techniques for surveying and selecting sites for navaids and the protection of ILS sensitive areas.

With our specialist engineering and project management teams, a seamless transition from project inception to final flight check is ensured.

Blue Quadrant is a leading supplier and installer of Non-Directional-Radio Beacons (NDBs) around the world.

NDB is a navigational system consisting of an automatic direction finder (ADF) and a radio transmitting unit. The automatic direction finder equipment is typically installed aboard an aircraft, and detects the NDB signal sent by the NDB transmitter stationed at a known location. The ADF determines the direction to the NDB transmitter, which is indicated by a relative bearing indicator (RBI). An RBI can be described as a kind of compass, except that the pointer that aims on the magnetic north in a magnetic compass, is substituted with at pointer to the NDB station on an RBI.

Non-directional beacon supports better and more precise aircraft navigation. In addition to sending out a morse code identity of the location, an NDB may also broadcast weather and meteorological information, as well as surface and terminal information.

Blue Quadrant has unrivalled experience in the supply, installation and commissioning of Distance Measuring Equipment (DME) systems.

Blue Quadrant DME is the ultimate choice in Distance Measuring Equipment combining quality with exceptional value for money. The equipment employs state-of-the-art technology ensuring high reliability in order to meet the demands of both civil and military requirements.

Integrity, reliability and maintainability are fundamental to the design concept of this system. The equipment has been tested under the most demanding environmental conditions, ensuring equipment operation in any environment.

Blue Quadrant DME is an easy to use system requiring minimal maintenance, that meets or exceeds all requirements. This enables interoperability with all currently available radio navigation aids on the market.

Within our engineering team we have some of the most experienced Doppler VHF Omnidirectional Range (DVOR) engineers in the world.

We can supply DVOR equipment and install on a full turnkey basis, or we can provide engineering expertise to support any stage of a DVOR project from site survey and safety case development to commissioning and maintenance support.

Installed at airports and en-route locations, the Doppler VOR Ground Beacon from Blue Quadrant is one of the primary navigational aids for a nation's airways system. It is a ground based, radio navigation aid, transmitting an omni-directional signal that enables an aircraft to determine its bearing relative to the location of the beacon.

Integrity, reliability and maintainability are fundamental to the design concept of this system. The equipment has been tested under the most demanding environmental conditions, ensuring equipment operation in any environment.

Blue Quadrant has benchmark in its delivery of turnkey Instrument Landing Systems (ILS) installations.

We have installed multiple ILS systems from the world's leading manufacturers, including several full ICAO CAT-III systems. As with all products we can provide full turnkey delivery, from civil works through to flight calibration anywhere in the world.

We can provide a whole package of tools to assist airports with aerodrome safeguarding, the design and preparation of instrument approach procedures, studies for the definition of equipment specification, system design - complemented where necessary by sophisticated computer modelling techniques for surveying and selecting sites for navigation aids and the protection of ILS sensitive areas.
