SAR-LUPE 4, also known as SAR-Lupe 4, is a reconnaissance and radar satellite launched on March 27, 2008, from the Plesetsk Cosmodrome LC132/1 launch pad using a Kosmos 11K65M launch vehicle. The satellite was manufactured by OHB and operated by BWB (Bundeswehr) with a mission focus on reconnaissance and radar operations. It has a configuration known as SmartLEO and is part of the SAR-Lupe bus system. With dimensions of 4 meters in length, 3 meters in diameter, and a span of 4 meters, its dry mass is 770 kg, matching its launch mass. The satellite is equipped with synthetic aperture radar (SAR), intersatellite S-band transmitter, and X-band transmitter for communication purposes. Its power system consists of solar cells and batteries to ensure continuous operation in orbit. SAR-LUPE 4 has a designed lifetime of 10 years and uses hydrazine thrusters for propulsion. The satellite's shape is described as cylindrical with a dish antenna, but specific details on its color, material composition, RCS value, ADCS system, transmitter frequencies, major events, constellation name, related satellites, and sources are not provided in the data given.
