Non-Directional Beacon (NDB)


Systems Interface is a leading supplier and installer of Non-Directional-Radio Beacons around the world.

Non-Directional Beacons (NDBs) are ground-based radio transmitters used to aid and navigate vessels in aviation and marine applications during their approach. NDBs transmit Omni-directional signals to an instrument onboard the aircraft/ship called an Automatic Direction Finder (ADF) that uses the signal to determine the designated landing location.

NDB Aviation Systems

They have continued to provide a fundamental and reliable means of aircraft navigation despite the arrival of GNSS and modern ground based systems. The decommissioning of non-directional beacon systems does not appear to be likely to occur for many years to come. For this reason manufacturers are investing in the development of modern ultra reliable systems.

Non-Directional Beacons 'Vector Series' 

We are agents for Nautel of Canada who, for over 35 years, have provided the lowest cost of ownership by making reliable products and supporting them with the industry's best customer service. Nautel are also one of the worlds' leading broadcast transmitter manufacturers and this heritage is apparent in the build quality and reliability of their products.

Nautel's 'Vector series' of NDB aviation transmitters dramatically improve system effectiveness and feature a range of models with outputs from 10W to 2KW. The Vector NDBs feature state-of-the-art digital technology including extensive remote control capability.

Antenna Tuning Units (ATUs) supplied with the Vector range feature both automatic reactance matching and automatic resistance matching, meaning that field strength remains constant even when varying environmental conditions and ground conductivity would seriously compromise conventional NDB systems.

It’s Time to Invest in NDBs

Many airfield operators continue to struggle on with old and unreliable equipment, expecting the NDB to become a redundant Navaid. However, with the UK wide DVOR rationalisation project underway, many DVOR guidance facilities will either be withdrawn or become unsupported, therefore an NDB will be the only means of navigating to Airports and conducting an approach for an aircraft not GPS equipped. Now is the time to consider a replacement. Systems Interface will be pleased to provide a budgetary quote for a modern, reliable trouble-free system.
