LONDON -- OneWeb, whose mission is to enable internet access everywhere for everyone, is delighted to announce the successful test of its six satellites in Low Earth Orbit. All satellites delivered high-speed, low-latency services, with speed of more than 400 Mbps which enabled the fastest real-time video streaming in Full HD from Space. The tests, which took place in Seoul, South Korea, represent the most significant demonstration of the OneWeb constellation to date, proving its ability to provide superior broadband connectivity anywhere on the planet.

OneWeb’s satellites are performing well, enabling the company to continue its path forward towards a fully functioning global constellation in 2021 and delivering partial service beginning as early as 2020. OneWeb’s service will broaden and innovate the use cases of satellite connectivity and will represent an important step towards enabling quality access everywhere for everyone.

OneWeb is aggressively moving forward on the implementation of its first phase of the network which will start with an initial 650 satellites and grow up to 1,980 satellites. This first phase of the constellation will provide global coverage; and further additions to the network will be focused on adding capacity to meet growing customer demands.

The recent satellite tests were conducted in partnership with Intellian, the developer and manufacturer of OneWeb user terminals and SatixFy, developer and manufacturer of the 125 MHz SCPC test modem. The tests included: latency, speed, jitter, seamless handover between satellites and power control. During its test, OneWeb demonstrated:

• Extremely low latency with an average of 32 milliseconds

• Seamless beam and satellite handovers;

• Accurate antenna pointing and tracking;

• Live streamed an ACDC music video at resolutions up to 1080p (Full HD); and

• Test speed rates of more than 400 Mbps.

From real-time gaming to Facetime, streaming HD movies to operating Google maps on the move or using cloud software, OneWeb’s service opens up a raft of new applications which are needed to meet the connectivity needs of today and tomorrow. These initial tests are only the beginning and OneWeb will continue testing as it prepares for its next launch later this year.
