Summary
ONEWEB-0108, also known as OneWeb SL0108, is a communication satellite designed and manufactured by ONEWUS in the UK. It was launched on March 25, 2021, from VOSTO using a Soyuz-2-1B launch vehicle at PU1S pad. The satellite uses an Arrow bus configuration with dimensions of 1.3 meters in length, 1 meter in diameter, and has a span of 5 meters when deployed. It weighs 148 kilograms at launch and operates on solar arrays and batteries for power supply. Equipped with a Ku-Band payload and SPT-50 or BHT-350 Hall effect thrusters for propulsion, the satellite is expected to have an operational lifetime of seven years. The shape of the satellite is described as Trapezoid+2 pan, and it belongs to the ONEWEBN constellation for communication purposes.
