OneWeb Launch 19 Liftoff

OneWeb said the liftoff took place on May 20, 2023, at 6:16 PT from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. OneWeb's satellites were efficiently separated from the launch vehicle and dispensed in eight phases over a span of 1 hour and 26 minutes.

OneWeb confirmed signal acquisition on all 16 satellites, marking OneWeb's fourth successful launch in collaboration with SpaceX.

With a total of 634 satellites now in orbit, OneWeb remains on track to provide global coverage by the end of this year and is actively scaling its services for customers worldwide. The addition of the newly deployed satellites from this mission significantly enhances the resilience and redundancy of the OneWeb constellation.

Innovative JoeySat Enhances Capabilities

The highlight of this launch is the inclusion of JoeySat, the 16th satellite deployed today. Developed through a partnership program between the European Space Agency and UKSA Sunrise, JoeySat features an innovative payload design that will demonstrate the capabilities of digital regenerative processing, electronically steered multi-beam arrays, as well as digital beamforming and beam-hopping technologies.

These advanced functionalities, planned for integration into OneWeb's Gen 2 constellation, offer enhanced flexibility and capacity to customers. This optimization of resources will enable real-time management of surges in commercial demand and facilitate rapid responses during emergencies, such as natural disasters.
