NovaSAR-S: Small satellite Synthetic Aperture Radar platform

NovaSAR-S is a small Synthetic Aperture Radar (SAR) mission designed for low-cost programmes and optimised for shared launch opportunites.  The system baselines SSTL-300 avionics flying on NigeriaSat-2, with an imaging payload developed by the space borne SAR team at Airbus in Portsmouth, UK, and S-band solid state power amplifer technology. 

NovaSAR-S is designed to operate independently, or in a constellation that will maximise imaging opportunities and data.  A constellation of three NovaSAR-S satellites can image any point on the globe every day, regardless of daylight or weather conditions. 

The first NovaSAR-S platform is currently in manufacture at SSTL, part-funded by the UK government.
