Спутник ДЗЗ. NovaSAR-S. [Редактировать]

NovaSAR-S это совместная разработка SSTL (Surrey Satellite Technology Ltd.), UK и EADS Astrium Ltd . Основной задаче проекта является создание радилокационного спутника который в основном будет работать с микроволновым диапазоно спектра.  При этом, по существующей традиции компания SSTL не собирается создавать спутник со сверхвысоким разрешением и сверхвысокой стоимостью, а ограничивается характеристиками требуемыми рынком.

NovaSAR-S Synthetic Aperture Radar NovaSAR—setting a new benchmark in affordability and performance for space-borne Synthetic Aperture Radar (SAR) systems NovaSAR-S delivers all weather mediumresolution Earth observation data night and day, at a price similar to traditional optical missions, and significantly lower than any other SAR platform currently on the market, by leveraging highly efficient S-band solid state technology. The platform is sized for a range of low-cost launch options. Applications NovaSAR-S provides medium-resolution (6–30 m) imagery ideal for applications including: Flood monitoring Agricultural crop assessment Forest monitoring (temperate and rain forest) Land use mapping Disaster management Maritime applications (e.g. ship detection and oil spill monitoring) SSTL NovaSAR-S NovaSAR combines our heritage SSTL-300 series avionics suite with a new structure and an innovative payload, developed in collaboration with EADS Astrium, that can be adapted to different frequency bands. NovaSAR-S Performance Flexible solutions NovaSAR-S Specification Imaging frequency S-band (3.1–3.3 GHz) Lifetime 7 years Mass <400 kg Lead time (KO to FRR) 24 months Antenna Microstrip patch phased array (3 m x 1 m) Imaging polarizations Single, dual, or tri-polar (HH, HV, VH, VV) Optimum orbit 580 km (SSO or low inclination Equatorial orbit) Payload duty cycle At least 2 minutes per orbit (single image >800 km long) Typical area coverage >1 million km2 per day (mode dependent) Downlink Rate 300 Mbps The NovaSAR-S platform can be supplied as a spacecraft or as part of a complete mission solution, and can be delivered in orbit from 2013. Surrey can provide flexible solutions according to customer needs including: The NovaSAR-S Synthetic Aperture Radar satellite Data processing and cataloging Ground segment based on heritage systems for spacecraft housekeeping Training in systems engineering, satellite operations, and image processing Baseline Imaging Modes The NovaSAR-S payload supports flexible imaging modes for a wide range of applications.
