3. Planetary Missions Division Miguel Almeida David Frew Mehran Sarkarati RSSD/STOC Decentralized Science Opportunity Analysing Operation Planning through Conflict Resolving - Decentralized science analysis carried out separately by payload teams - Science analysis data and tools needed by each payload team - Conflicting, date/time-related operation requests received by SOC from payload teams - Satellite operational activities and the related constraints are know only at SOC - Iteration cycles are needed to resolve the raising conflicts. - Open Cycle Planning Concept

5. Planetary Missions Division Miguel Almeida David Frew Mehran Sarkarati RSSD/STOC Centralised Science Opportunity Analysing Conflict Free Operation Planning - Scientific data input from the payload teams into a central mission repository - Direct link between the observation requests and scientific objectives of the mission - Centralised science opportunity analysing for the complete mission in early phases - Reduced iteration cycles due to the conflict free planning concept - Providing payload teams with identified science opportunities for each mission phase - Decision making and prioritising based on the results of the science analysis - Complete, centralised tracking of performed observations and their feed back for future planning - Closed Cycle Planning Concept
