Summary
The ONEWEB-0169 satellite, also known as OneWeb SL0169, was launched on March 25, 2021, from the Vostochny Cosmodrome using a Soyuz-2-1B launch vehicle. This communication satellite is part of the UK-based Oneweb constellation and utilizes an Arrow bus configuration manufactured by ONEWUS. The spacecraft measures 1.3 meters in length, has a diameter of 1 meter, and spans 5 meters when its solar arrays are deployed. With a dry mass of 140 kilograms and a launch mass of 148 kilograms, it is designed to operate for approximately seven years. Equipped with a Ku-Band payload, the satellite uses SPT-50 or BHT-350 Hall effect thrusters as its motor system and solar arrays along with batteries for power generation. The shape of the spacecraft consists of a trapezoid body with two panels.
