Scientists, Academics, Organizations, etc. CLOUD CONCLUSION AND FUTURE WORKS

EOS satellite mission is expensive, optimize mission planning should be highly considered. Co-constellation is also a way to optimize space sensor resources. This presentation gives the overview of the OPTEMIS mission planning system, its concept, current development/implementation status and its demonstration. EOS satellite is the sensor resource that is, by nature, easy to be shared globally. Viable balanced solutions for EOS co-constellation is presented. With a correct tool, to sharing, collaborating and harmonizing satellite resources is easily achievable. • OPTEMIS can be used to manage and facilitate observation requests, satellites acquisition planning. Speed-up the workflow and let the end-users use the satellite resources efficiently.

FUTURE WORKS: Multi-language OPTEMIS, Real-time summary dashboard, Multi- sensor Tasking Harmonization
