Surrey Satellite Technologies (SSTL) announced today that they will begin developing a low-cost Synthetic Aperture Radar (SAR) satellite system. The medium resolution (6-30 m ground sample distance) NovaSar-S is being developed alongside SSTL’s parent company Astrium. The satellite platform (SSTL-300) will be an adaption of SSTL’s very-high-resolution imaging NigeriaSat-2 mission, which was launched in August. [...]
