SAR Constellation for Low Cost and Rapid Earth Monitoring

Massive communication constellations in development such as OneWeb are redefining the concept of constellations, offering serial production of hundreds of satellites with a low recurrent cost. In this SAR constellation concept Airbus has taken such a low cost platform with the benefits it offers and paired it with a low cost SAR payload offering an attractive solution to constellations. A maritime surveillance constellation configuration to offer global access in <;3hrs with only 16 satellites utilizing this approach is presented.
