Chelys was established in 2002. Our core business focuses on software development and supplying services in the Earth Observation sector, by providing processing stations for Earth Observation satellites. We are specialized in satellite data management and real time satellite (raw) data processing, data quality control, image generation, projection and mosaics. Our main product, the Satellite Rapid Response System, is a multimission real-time data processing and quality control system that is able to simultaneously process data coming from several different missions. The SRRS system used by ESA, called MIRAVI, has been installed in all Envisat satellite acquisition stations and has been delivering thousands of images per month since June 2006. Our current areas of activity are: - software development - environmental acquisition and processing systems - data acquisition systems (ESA/DDS, EUMETCAST) - image generation from raw data, orthorectification and mosaics
