In a world first, ESA and Telesat have efficiently related a Low Earth Orbit (LEO) satellite tv for pc to the bottom utilizing 5G Non-Terrestrial Community (NTN) expertise within the Ka-band frequency vary, marking a vital step in the direction of making space-based connections so simple as utilizing a cell phone.
This achievement opens up prospects that have been beforehand out of attain, as low-flying satellites mixed with standardised 5G expertise can now help providers requiring real-time, interactive connections. The breakthrough may rework how we deal with emergency response, present rural healthcare, and help distant industrial operations worldwide.
ESA’s 5G/6G laboratory at its European Area Analysis and Expertise Centre (ESTEC) within the Netherlands efficiently related to the LEO 3 satellite tv for pc operated by Telesat, a number one world satellite tv for pc operator. The take a look at was made attainable by way of a Memorandum of Understanding signed earlier this yr between ESA and Telesat, which offered entry to the LEO 3 demonstration satellite tv for pc. The LEO 3 satellite tv for pc serves an vital position for low-latency buyer purposes testing, in addition to antenna and modem improvement.
Utilizing Amarisoft’s 5G expertise, the workforce established and maintained a secure reference to the satellite tv for pc because it moved throughout the sky, from simply above the horizon to its peak elevation of 38 levels and again down once more. Whereas comparable experiments have been carried out with satellites in geostationary orbits, this marks the primary profitable implementation of 5G NTN expertise with a LEO satellite tv for pc shifting quick with respect to a person on the bottom.
From enabling distant surgical procedure by way of dependable telehealth providers to supporting autonomous automobiles, the purposes opened up through the use of 5G NTN applied sciences are far-reaching. The system additionally gives alternatives to offer connectivity for catastrophe response groups, preserve civilians related in distant places, and even improve in-flight web providers.
The important thing innovation of this experiment was the usage of open requirements, developed by the Third Technology Partnership Venture (3GPP) – the worldwide organisation that creates telecommunications requirements – reasonably than proprietary waveform expertise. Which means cell gadgets may probably join straight to satellites (a situation often called direct-to-device), probably decreasing the associated fee and complexity of terrestrial infrastructures and growing interconnectivity between completely different suppliers. In idea, the expertise permits seamless switching between ground-based networks and satellites, making certain steady protection whether or not you might be in a metropolis centre or on a distant mountainside.
This work types a part of ESA’s Area for 5G/6G and Sustainable Connectivity strategic programme line, which goals to combine mobile networks with space-based networks to attach everybody, in all places, always.
Antonio Franchi, ESA’s Head of the 5G/6G Non-Terrestrial Community (NTN) Programme Workplace, inside the Area for 5G/6G and Sustainable Connectivity programme mentioned: “We’re proud to proceed to drive European technological management and innovation within the area of Non-Terrestrial Networks. Assessments reminiscent of this showcase ESA’s position in supporting the event of modern 5G and 6G techniques that unlock social and financial alternatives for individuals and companies. This initiative celebrates the good collaboration between ESA, Telesat and Amarisoft!”
Alberto Ginesi, ESA’s Head of the Telecom Techniques and Methods Part of the Directorate of Expertise, Engineering, and High quality (TEC) mentioned: “This world-first experiment demonstrates ESA’s technical excellence in advancing broadband satellite tv for pc entry expertise. Constructing on the 3GPP standardisation teams’ approval, we have confirmed 5G NTN specs over an actual non-geostationary orbit satellite tv for pc hyperlink. By means of this achievement, we have proven ESA’s functionality to help superior satellite tv for pc broadband networks, paving the best way for upcoming initiatives reminiscent of IRIS². I’d wish to recognise the work Augusto Marziani, Stefano Cioni and Matteo Conti for finishing up this experiment.”
Mario Neri, Telesat’s Director of Spectrum Technique, Innovation and Area Sustainability, mentioned: “This exercise allowed testing the lately standardised 5G NTN expertise in a real-world situation, utilizing the Ka-band spectrum over our LEO 3 satellite tv for pc – one thing that nobody had ever executed earlier than. This confirms Telesat’s engagement in always exploring modern satellite tv for pc applied sciences that may enhance life on Earth.”
Marouan Benabdellah-Chaouni, Senior Vice President at Amarisoft, mentioned: “Inexpensive expertise is on the coronary heart of Amarisoft’s mission. With 5G over satellite tv for pc, we’re making world connectivity extra accessible. This achievement, in collaboration with ESA and Telesat, highlights Amarisoft’s management in cutting-edge 5G expertise and the ability of modern partnerships to advance non-terrestrial communication.”
