TOKYO, Nov 15, 2021 - (JCN Newswire via SEAPRWire.com) - Airbus and NTT DOCOMO, INC. have demonstrated the ability to use its solar-powered Zephyr High Altitude Platform Station (HAPS) to deliver future wireless broadband connectivity. The trial took place in the United States in August, when the Zephyr S aircraft undertook approx. 18-day stratospheric flights to test various capabilities.Carrying an onboard radio transmitter, the Zephyr S provided an agile datalink during a stratospheric flight to simulate future direct-to-device connectivity. Test data was captured at different altitudes and at different times of day and night, focusing on assessing how connectivity is affected in the stratosphere by factors including weather conditions, different elevation angles and aircraft flight patterns.Tests included various bandwidths to simulate direct-to-device service from the HAPS to end users using low, nominal and high throughput. The demonstration confirmed the viability and versatility of the 2GHz spectrum for HAPS-based services and also the use of a narrow (450MHz) band to provide connectivity in a range of up to 140km.The measurement and analysis of the propagation of radio wav...

SINGAPORE - The Republic of Singapore Air Force (RSAF) has started taking delivery of the improved H225M medium-lift helicopters in Singapore, meant to progressively replace the Super Puma workhorses that have been in service since 1983. In a Facebook post on Monday (March 29), the RSAF said it will be conducting flight tests and training on the H225M helicopters, which are manufactured by European planemaker Airbus. "When operationalised, the H225M helicopters will take over the roles of the Super Pumas," the RSAF added. A Mindef spokesman told The Straits Times earlier this month in response to queries that the RSAF will start taking delivery of three helicopters in the coming months. The H225M has about 20 per cent longer range capability than the AS332M Super Pumas, and will complement the CH-47 helicopters to meet the Singapore Armed Forces' lift requirements for a wide spectrum of operations, said the RSAF. This includes aeromedical evacuations, search and rescue, humanitarian assistance and disaster relief and maritime security operations. In a statement on Monday, Airbus Helicopters chief executive Bruno Even said the delivery was "exceptionally significant", as Airbus and ...
