London and Farnborough, UK – 13 January 2020 (OneWeb/SatixFY PR) — OneWeb and SatixFy UK today announce plans to add a digital technology pathway payload that will include a full digital payload into OneWeb’s launch schedule during 2021.
This new technology will pave the way for satellites with a higher level of flexibility to efficiently support peaks in demand without oversizing the constellation.
The digital-transparent payload will demonstrate full Beam Hopping capability in both Forward and Return Links. It will include an On-Board-Processing subsystem capable of running independent links on the User and Gateway links on the ground with different capacities. Electronically Steered Multi-Beam Antenna with True Time Delay beam-forming, capable of pointing and switching multiple beams to multiple directions simultaneously are an additional major feature.
Active areas are dynamically allocated much higher capacity than areas that do not require as much bandwidth and are just being scanned to gauge demand.
The Beam hopping capability also enables seamless handover for mobile devices, between beams and satellites. An example would be an Aero terminal for In-Flight Connectivity, able to operate on both LEO and GEO simultaneously and maintaining make-before-break connectivity between the rising and setting satellites. Maximum capacity can be directed ...
