United Airlines’ Boeing 767 aircraft to be equipped with Cobham’s AVIATOR 300D and Inmarsat’s SwiftBroadband-Safety LONDON, 15-Jun-2017 — /EuropaWire/ — Inmarsat, the world’s leading provider of global mobile satellite communications, and Cobham SATCOM, the leading manufacturer of satellite communications solutions, today announced that United Airlines will participate in a technology evaluation of SwiftBroadband-Safety (SB-S), Inmarsat’s next generation flight deck communications platform. SB-S will be evaluated on four United Airlines’ Boeing 767 aircraft, which will be installed with Cobham’s AVIATOR 300D satcom system. It offers global, high-speed, secure connectivity for the flight deck. Enabling powerful and flexible communications with real-time inflight information, the service enhances airline safety, asset utilisation, security, and operations. United Airlines’ evaluation of the IP-based broadband service is part of the aviation giant’s ongoing commitment to best-in-class operations, safety and service. During this evaluation, United Airlines will deploy its equipped planes in the highly congested North Atlantic airspace. It will use the new platform for communications and surveillance with Controller-Pilot Data Link Communications (CPDLC) and Automatic Dependent Surveillance Contract (ADS-C) messaging. SB-S also provides a range of ‘always on, always secure’ applications, which United Airlines will be able to use. These include continual positional awareness for flight tracking, flight data streaming (known as “Black Box in the Cloud”) and real-time electronic flight bag applications, such as networked graphical weather. Operational benefits include more fuel-efficient routes and the ability to transmit vital aircraft performance and positioning data in real time. Installations of the AVIATOR 300D systems on United Airlines’ planes are scheduled to commence later this year. The systems include Cobham’s IGA-5001 Intermediate Gain Antenna and will use the AVIATOR 300D Supplemental Type Certificate developed by L2 Aviation. Chuck Stewart, United Airlines Chief Technical Pilot for Communications, said: “United is excited about installing and using this powerful new communications capability as we expect to see it enhancing our operational efficiency, especially in places like the North Atlantic.” Andy Beers, Director, Global Aero Sales, Cobham SATCOM, said: “We are excited about this latest opportunity to contribute to the ongoing evaluation of SwiftBroadband-Safety as it supports our development of communication technologies Cobham SATCOM is rolling out to meet the future needs of the aviation community, particularly our AVIATOR S Series next generation product line, designed specifically to leverage Inmarsat’s new SB-S services.” Captain Mary McMillan, Inmarsat Aviation Vice President of Safety and Operational Services, said: “As a progressive and innovative airline, United is making an important move anticipating the future of aviation. With SB-Safety’s secure broadband platform, it will be able to benefit from the fully connected flight deck that delivers improved safety and security, better efficiency and optimised fleet performance.” In June 2016, Airbus announced it selected SwiftBroadband-Safety and Cobham’s AVIATOR S series avionics for the cockpit safety communications solution for its popular A320 and A330 families of aircraft. In May 2017, Shenzhen Airlines announced its evaluation of the next-generation SwiftBroadband-Safety platform with Inmarsat and Cobham to address the needs of the rapidly-growing Chinese aviation market. In November 2016, Inmarsat, Cobham and Hawaiian Airlines announced that SwiftBroadband-Safety and Cobham avionics had enabled in-air Electronic Flight bag connectivity for the first time with Hawaiian Airlines.

Thanks to satellite communications, airlines have saved over $3 billion in the last 15 years according to a recent Helios study.

In this paper a 24 GHz integrated front-end transceiver for vital signs detection (VSD) radars is described. The heterodyne radar transceiver integrates LO buffering and quadrature splitting circuits, up- and down-conversion SSB mixers and two cascaded receiver LNA's. The chip has been manufactured in a 0.25 μm SiGe:C BiCMOS technology and its size is 1390 × 2690 μm2. The transmitter demonstrates a maximum output power at 24 GHz of approximately -30 dBm with an externally applied LO power of 3 dBm. The receiver demonstrates a peak gain of 13.3 dB at 22.15 GHz with >10 dB return loss. The power consumption of the entire transceiver is approximately 164 mW. © 2013 IEEE.

An automated, low-field disturbance probe positioning system for measuring 3-D electric field distributions inside vehicles or similar resonant environments is described. Correlations between measured and simulated electric field distributions for a simple rectangular cavity demonstrate that the probe positioner has little impact on the measured field levels. Comparisons between measurements and simulations for a real vehicle indicate that the predicted field population distributions are within the estimated uncertainties of the measurements. © 1964-2012 IEEE.

This letter documents the design, manufacturing, and testing of a single-layer dual-band circularly polarized reflectarray antenna for 19.7-20.2 and 29.5-30.0 GHz. The reflectarray is designed using the concentric dual split-loop element and the variable rotation technique that enables full 360° phase adjustment simultaneously in two separate frequency bands. The elements have been optimized to suppress cross-polar reflection. Thereafter, the element data is included in a design tool that computes the reflectarray layout and the associated radiation patterns. The reflectarray is composed of 80 × 80 elements printed on a 40 × 40-cm2 Rogers 5880 substrate. The antenna has been manufactured and measured at the DTU-ESA Spherical Near-Field Antenna Test Facility. The peak gain is 35.8 and 40.0 dBi at 20.0 and 29.8 GHz, respectively, and the aperture illumination efficiency is in the range of 53%-63% over the two frequency bands. © 2013 IEEE.

A shared aperture antenna for simultaneous operation at L- (1525 to 1661 MHz) and Ka-band (19.7 to 20.2 GHz and 29.5 to 30.0 GHz) is demonstrated. This stacked antenna consists of a Ka-band reflectarray antenna with a frequency selective surface (FSS) ground-plane above an L-band patch array antenna. The reflectarray is based on the concentric dual split-loop element backed by a concentric dual-loop FSS element. The reflectarray comprises 80 × 80 elements and it is printed on a 40 × 40 cm2 Rogers 5880 substrate, while the L-band antenna is a 2 × 2 patch array. The reflectarray antenna has been manufactured at the Technical University of Denmark (DTU) and measured at the DTU-ESA Spherical Near-Field Antenna Test Facility. The reflectarray provides a maximum directivity of 36.4 and 38.5 dBi at 20.0 and 29.8 GHz, respectively, and an aperture illumination efficiency in the two frequency bands up to 57% and 48%, respectively. There is very little degradation in the L-band patch array performance due to the reflectarray, and it provides a minimum directivity of 11.8 dBi over the L-band. © 1963-2012 IEEE.
