Elecnor Deimos coordinates EO-ALERT, a EU R+D project of H2020 2017 space call, with the participation of DLR, Graz University of Technology, Politecnico di Torino, OHB Italia and Deimos Imaging, an UrtheCast Company, as well as the Spanish State Meteorological Agency (AEMET), as a third party.
EO-ALERT project aim is to achieve very high throughput and very low latency in the delivery of Earth observation images and image products. While the market for EO image products is growing, the classical EO data chain generates a severe bottleneck problem, given the very large amount of EO raw data generated on-board the satellite that must be transferred to ground, slowing down the EO product availability, increasing latency, and hampering applications to grow in accordance with the increased user demand for EO products. EO-ALERT project is to move beyond the state of the art, by providing a high-speed data chain, with increased EO data chain throughput, that facilitates the transfer of EO data products with very low latency data to the end user. This will open up EO data to new applications, facilitating their use in everyday life.
The proposed solutions are based on a novel flight segment architecture that moves optimised key EO data processing elements from the ground segment to the satellite. This goal necessitates innovation in several critical technological areas; namely on-board reconfigurable data handling, on-board image generation, on-board image processing, high-speed on-board avionics, on-board data compression and reconfigurable high data rate communication links to ground.
