Why plan your airport’s future around antennas from the past or continue to delay your airport’s future while awaiting a reliable GNSS landing system solution? – Instead, take control of your airport’s future now and discuss the operational, financial and environmental advantages of Watts Antenna Company’s Advanced ILS Antennas with your airport consultants and move your airport ahead.

Let’s take this questions one part at a time. First, why design your airport’s future around antennas from the past? Years ago many airports began experienced flight delays during times of high volume of traffic and low visibility conditions. At numerous airports when delays occurred, it would cause a condition known as “multi-taxi” referring to lines of aircraft waiting to fly out of the airport. There was pressure upon ATC to allow aircraft to taxi forward ignoring the ILS Critical Area markings in order to increase throughput capacity. This procedure caused dangerous signal interference for aircraft on ILS approach and remains a serious chronic procedural safety risk at airports throughout the world.

Now to address the second part of the question. Why hold up an airport’s future waiting for reliable WAAS or GBAS. Many airports have deferred making cost effective improvements to their ILS believing that GNSS solutions such as WAAS or SBAS are forthcoming to replace the ILS. The truth is, however, that after more than 20 years, neither of these systems meet reliability metrics as defined by the FAA or ICAO that would allow them to replace the ILS because both rely on weak easily disrupted GNSS signals. The situation, in fact, is worsening as the incidents of GNSS signal disruptions from spoofing and jamming are on the rise. Don’t take our word for it, do your research. Here is a good place to start.

Advanced ILS Antennas localize ILS signals in the approach region and inside airdromes rather than diffusing them as do legacy antennas. By reflecting a much narrower beam and directing it with greater precision, they free up areas to allow additional aeronautical and non-aeronautical income producing construction opportunities i.e. hangers, terminals, storage facilities, runways, taxiways, highways, railways, hotels, Apartments, office buildings, etc.

At many airports around the world, our End-Fire Glide Slope Advanced ILS Antennas have made the difference between having a precision approach and not having one as airport siting characteristics such as challenging terrain conditions, tidal variations, insufficient ground plain conditions and other sources of dynamic and static RF signal errors could not otherwise be cost effectively remedied. That is why the End-Fire is considered to be the “Tough Site Solution”

Imagine being able to plan, design and build airport infrastructure constrained only by the limits of physical space and not by the signal behavior of any particular landing system.  Or imagine installing an ILS where you had been told would be cost prohibitive. Imagine the efficiencies produced when aircraft and ground crews are able to move about unencumbered by ILS Critical and Sensitive Areas, pilots landing confident of uninterrupted coupled approaches and ATC managing fewer numbers of delayed surface and airborne traffic. Now, imagine saving millions on site prep excavation or environmental wetlands mitigation and ending up turning a regional airport into an economic catalyst for the entire local community.

Intrigued? You don’t have to imagine these capabilities, you can get them! They are available right now from Watts Antenna Company. We have ILS solutions for all airport environments. From mountaintops to seaside locations, we can provide you a high performance Advanced ILS solution.

Watts Antenna Company manufactures high performance advanced ILS Antenna systems that can be utilized to increase airport capacity and efficiency or simply to provide ILS at the world’s toughest sites. For stand alone ILS Antenna System solutions or as comparable performance backup antenna systems for GPS/GNSS, either way, we will significantly increase the efficiency and capabilities of every airport in which our antennas are installed!

Pressure is intense on airports, particularly smaller ones, to employ their facilities in the most economically advantageous ways. For example, the inability to situate large hangars due to multipath concerns related to the use of standard ILS Antennas can disqualify some airports from coveted hub status. While ILS transmitter and monitor technology have significantly improved over the years, ILS antenna technology worldwide has lagged well behind.  The standard ILS Antenna array has relatively the same performance and overall design as it had for the past several decades even though it is the most important subsystem in providing improvements to any airspace system. While innovations have been limited due to lack of funding and interest, Watts Antenna Company, believing ILS had more to contribute, continued to innovate and to privately self fund Advanced ILS R&D.

Today, Watts Antenna Company has a full complement of Advanced ILS Antennas capable of significantly reducing ILS Critical and Sensitive Areas while simultaneously increasing airport capacity and operational safety wherever our antennas are deployed regardless of how challenging your sites may be.
