Airbus, NTT, DOCOMO and SKY Perfect JSAT Jointly Studying Connectivity Services from High-Altitude Platform Stations (HAPS)
press release
TOKYO, JAPAN, January 17, 2022 – Airbus, Nippon Telegraph and Telephone Corporation (NTT), NTT DOCOMO, INC. (DOCOMO) and SKY Perfect JSAT Corporation (SKY Perfect JSAT) jointly announced that they have begun studying the feasibility of collaborating on future high-altitude platform stations (HAPS)-based connectivity services as part of a future space-based wireless connectivity ecosystem.
Launched with a memorandum of understanding (MOU), the study aims to identify the early deployment requirements of a HAPS-based network. The collaboration will investigate the use of the Airbus Zephyr, the leading fixed wing, solar-powered, stratospheric unmanned aerial system (UAS), and the wireless communication networks of NTT, DOCOMO and SKY Perfect JSAT in order to test HAPS connectivity, identify practical applications, develop required technologies and ultimately launch space-based wireless broadband services.
In the global push to further advance 5G and eventually introduce 6G, initiatives are under way to expand coverage worldwide, including in the oceans and in the air, as well as remote and hard to reach areas. Such initiatives will include HAPS, which fly in the stratosphere about 20 km above the earth, and non-terrestrial network (NTN) technologies using geostationary-orbit (GEO) satellites and low Earth-orbit (LEO) satellites. HAPS networks are deemed to be a relatively easy solution for air and sea connectivity and an effective platform for deploying disaster countermeasures plus have many industrial applications. The provision of space-based radio access network services using NTN technologies, collectively called Space RAN (radio access network), is expected to support worldwide mobile communications with ultra-wide coverage and improved disaster resistance as well enhanced 5G and 6G. In addition, HAPS platforms can also interconnect to the nearest terrestrial network gateway and extend the reach of existing mobile services directly to end-user devices, providing service options including rural, emergency and maritime connectivity.
With the signing of the MOU, the four companies will discuss and identify possible future developments necessary to unlock future HAPS-based connectivity services, lobby for standardization and institutionalization of HAPS operations, and explore business models for commercializing HAPS services.
Specific themes will include the applicability of HAPS for mobile connectivity on the ground and base station backhaul,1 the performance of various frequency bands in HAPS systems, the technological considerations for linking HAPS with satellites and ground base stations, and the establishment of a cooperative system to test a network combining NTN technology, satellites and HAPS.
As separately announced on November 15, 2021, DOCOMO and Airbus successfully conducted a propagation test between the ground and a “Zephyr S” HAPS aircraft in the stratosphere, demonstrating the possibility of providing stable communication with such a configuration.
1 Base station backhaul refers to a fixed line that supports high-speed, high-capacity information transmission between a large number of wireless base stations in a mobile communications network and the core network.

Reusable scramjet launch system to pave way for hypersonic airliners
Australian company Hypersonix Launch Systems is not only looking to make the delivery of satellites into orbit cheaper and more accessible, but also greener. It is developing a reusable launch system powered by green hydrogen that would deliver small satellites into orbit without producing any carbon emissions or other noxious gases – and is eyeing off hypersonic airliners further down the line.

EMBRAER AND AERNNOVA ANNOUNCE NEW STRATEGIC PARTNERSHIP IN ÉVORA - Aernnova Web
– Under the terms of the partnership, Aernnova acquires Embraer industrial plants in Évora, Portugal, and a long term supply agreement is signed between both companies
Embraer and Aernnova, today announced a strategic partnership for Embraer Metálicas and Embraer Compósitos industrial units, located in the Aeronautical Industry Park of Évora, Portugal. The transaction contemplates the sale of all shares of company's wholly owned subsidiaries to Aernnova. Under the terms of the partnership, Aernnova assumes the operation of the industrial plants in Évora at the same time as it signs a supply agreement to secure current production packages for Embraer aircrafts. Évora facilities activity will add around US$ 170 million to Aernnova's revenues figure.
With 37,100 and 31,800-square meters respectively, and employing around 500 people, these facilities combine the most advanced technologies in both metallic and composite airframe construction with a high level of digitalization and automation of plant production processes. Among other activities both factories produce parts for wings, vertical and horizontal stabilizers for programs such as the Praetor 500 and Praetor 600 business jets, the two generations of the E-Jets family of commercial jets and the multi-mission aircraft C-390 Millennium. Évora industrial units will constitute Aernnova's largest production center in the world.
This agreement strengthens the Aernnova's position as a tier 1 supplier for single-aisle aircraft, and improves its presence in the executive and defense aerospace markets. The industrial capacity at Evora plants will also allow Aernnova to further expand Evora current activities with new contracts either from Embraer or other aircrafts manufacturers.
"We are pleased to announce this partnership with Aernnova, a world renowned supplier in the aerostructures segment, which will allow for increasing the occupation level of the factories in Évora, to diversify its client base and to bring new business opportunities," said Francisco Gomes Neto, President and CEO of Embraer.
Mr. Ricardo Chocarro, CEO of Aernnova, said: "This deal is another step forward in Aernnova's growth strategy, further underlining the company's status as a global leader in the design and manufacturing of aerostructures. We plan to further develop the operations of the facilities, and establish Évora as a global aerostructure manufacturing benchmark, with the technical and commercial support of Aernnova group, and with the continuous commitment of the company to a digital and sustainable aeronautical industry"
The closing of the transaction is subject to the completion of certain conditions which the parties expect to accomplish in the first quarter of 2022.
