Summary
ONEWEB-0338, also known as OneWeb SL0338, is a UK-built communication satellite using an Arrow bus configuration. It was launched on September 14, 2021, from the TYMSC launch site LC31 aboard a Soyuz-2-1B rocket. The satellite has dimensions of 1.3 meters in length and 1 meter in diameter with a span of 5 meters and weighs 148 kg at launch, reducing to a dry mass of 140 kg. Equipped with a Ku-Band payload for communication purposes and solar arrays along with batteries for power supply, it is expected to have an operational lifetime of seven years. The propulsion system includes SPT-50 or BHT-350 Hall effect thrusters. The satellite's shape is described as Trapezoid+2 pan, but specific details on its color, radar cross-section (RCS), attitude determination and control subsystem (ADCS), material composition, and related satellites are not provided.
