National Satellite Ocean Application Service
Chinese national ocean satellite application organisation surfaced as the HY ocean-satellite operator and data distributor.
National Satellite Ocean Application Service is a Chinese ocean-satellite application organisation associated with HY ocean satellite data and operations.[1][2][3] Its Earth-observation role covers HY ocean-colour, ocean-dynamics, and ocean-surveillance satellite series, including operator and data-service functions for Haiyang ocean satellites.[1][2][3] For buyers, NSOAS is the agency profile linked to Chinese ocean-observation missions and data distribution around the HY-1 and HY-2 series.[1][2][3]
