Journey time saving International greenhouse gas emissions reduction £162m Annual benefits delivered by HS1 Bordeaux Saint-JeanHS1 Ltd said it was ‘working with international partners to connect direct services to Bordeaux, along with other new international destinations including Frankfurt, Düsseldorf, Köln and Genève’.Taken together, such services could generate up to 1∙6 million more passenger journeys a year on HS1.Proposals for a direct London – Bordeaux service have been under discussion over the last two years with Eurotunnel, SNCF Réseau and French infrastructure concessionaire Lisea. HS1 Ltd predicts that up to 200 000 passengers a year would use the route. The service would initially be seasonal, according to Crowther, similar to the summer Eurostar service between London, Avignon and Marseille. Journey time would be less than 5 h.#*#*Show Fullscreen*#*# International High Speed 1HS1 Ltd used the occasion to announce details of an analysis prepared on its behalf by consultants Steer outlining the socio-economic benefits of HS1 and the environmental advantages of high speed rail.Steer calculates that HS1 generates £427m of economic benefits a year, amounting to £4∙5bn since the line opened fully in 2007. In 2010-17, demand for domestic high speed services rose by 93% to 15 million trips a year.‘We have reduced CO2 emissions by the equivalent of 60 000 short-haul flights every year’, wrote Dyan Crowther in her foreword to the report, noting that ‘this study is an invitation to look forward … We have capacity on our tracks and with our partners, we can deliver more of the benefits outlined here.’The report says there is ‘currently capacity available to provide more domestic and international services on HS1 which could result in more than £101m of additional economic benefits and 0∙5 million tonnes less carbon emissions each year’. £23m £7m 15 million Crowding, reliability and quality improvements Tourist spend EUROPE: Commemorative boards were unveiled at a ceremony at London’s St Pancras station on March 5 to mark a twinning agreement with Bordeaux Saint-Jean. The event was attended by UK Minister of State for Rail Chris Heaton-Harris and Diego Diaz, President of SNCF International, who suggested that a direct London – Bordeaux service could be launched in 2022.Dyan Crowther, Chief Executive of High Speed 1 Ltd, operator of the high speed line between London and the Channel Tunnel, said that ‘today we celebrate the power of high speed rail’. More people are switching to rail as the most environmentally-friendly way of travelling between the UK and a growing list of destinations in mainland Europe, she said.#*#*Show Fullscreen*#*# Productivity improvements Journeys £33m Output £2bn £169m £66m £66m £129m £7m Domestic 11 million Total 26 million UK environmental benefits £86m £83m £2bn
Leading RF antenna solutions provider, ThinKom Solutions, has completed a series of interoperability tests that demonstrate the compatibility of its core antenna technology with a Low-Earth Orbit (LEO) satellite network. The tests were conducted during the first quarter of 2020, using commercially available airborne-certified hardware, including a ThinKom Ku3030 phased-array antenna subsystem and a Gogo radome, adaptor plate and power amplifier that together form the “2Ku” AERO SATCOM terminal.The 2Ku terminal demonstrated rapid acquisition and tracking of LEO satellites and provided continuous connectivity over all operationally relevant elevation angles. The switch time between individual satellite beams was less than 100 milliseconds (ms), and handoffs between satellites were completed in less than one second. Switches between LEO and geostationary (GEO) satellites were also achieved with similar results.The measured terminal performance demonstrated the potential that the combination of ThinKom antennas and LEO solutions will provide, with throughput rates in excess of 350 Mbps on the downlink and 125 Mbps on the uplink, at latencies of less than 50 ms.LEO satellite networks have the potential to be transformative to the in-flight connectivity experience, but also place new stringent demands on the antenna systems used to track and connect with the rapidly moving satellites. ThinKom’s demonstration is another milestone verifying that the company’s antenna technology operates effectively in the LEO environment, which is a key requirement for airlines in terms of enhanced network resiliency and flexibility.ThinKom has successfully tested its Ku- and Ka-band COTS phased-array aero antennas across commercial and military frequency bands and a wide range of GEO and non-geostationary (NGSO) satellites over the past 12 months. In all cases, the phased-array antennas have consistently demonstrated high throughput operation and rapid reliable handoffs, including both intra- and inter-satellite switching.Click here to learn more about the ThinKom Ku3030 phased-array antenna subsystem.
