Summary

The ONEWEB-0154 satellite, also known as OneWeb SL0154, was launched on March 25, 2021, from Vostochny Cosmodrome using a Soyuz-2-1B launch vehicle. It has dimensions of 1.3 meters in length and 1 meter in diameter with a span of 5 meters. The satellite features an Arrow bus configuration and weighs 148 kilograms at launch, reducing to a dry mass of 140 kilograms. Equipped with a Ku-Band payload and powered by solar arrays and batteries, it is designed for communication purposes. Manufactured by Onewus in the UK, ONEWEB-0154 uses SPT-50 or BHT-350 Hall effect thrusters as its propulsion system and has an expected operational lifetime of 7 years. The satellite's structure is shaped like a trapezoid with two panels and is owned by OneWebN for communication services in space.
