Summary
The ONEWEB-0306 satellite, also known as OneWeb SL0306, was launched on September 14, 2021, from the TYMSC launch site using a Soyuz-2-1B rocket from LC31 pad. It is part of a communication mission operated by ONEWEBN and manufactured by ONEWUS in the UK. The satellite has an arrow bus configuration with dimensions of 1.3 meters in length, 1 meter in diameter, and a span of 5 meters. Its dry mass is 140 kilograms, and it was launched at a mass of 148 kilograms. Equipped with a Ku-Band payload and solar arrays for power, the satellite is designed to operate for approximately seven years using SPT-50 or BHT-350 Hall effect thrusters as its propulsion system. The structure of the satellite has a trapezoid plus two panel shape but lacks specific information on its attitude control systems or color.
