Participants engaged in productive brainstorming on a common problem in modeling, focusing on coordination and time reference frames. Looking to the modeling and simulation community for insights to enhance the description of reference frames. Seeking improvement on existing assets and exploring mathematical formalisms. Collaboration with the Telescope Challenge Team for beta testing. Exploring approaches through a body of knowledge and engaging with standards bodies. Seeking audience volunteers for input. Dimensions include time concepts and analysis connections.

Hour Activity • Went through a brainstorming exercise on a common problem with linking models – getting the common vocabulary / ontology • Intended to be both productive and instructive for participants • Two groups formed • Chose two common aspects – coordinate / reference frames and coordinated time
Reference Frame • Noted that SI Library / QUDV already exists for describing units and measures in a line • Want to look to the modeling and sim community for ideas • Improve upon the FireSat description of RFs • Relevant UML assets exist and were volunteered by a participant in the discussion • Need to represent both descriptively and in different mathematical formalisms (e.g., rotation matrices v. quaternions) • Telescope Challenge Team has volunteered to be a beta tester
Time • Decided on approaching the problem through body of knowledge • Standards bodies (e.g., NIST, OASIS, etc.) • Modeling and simulation • Volunteers from the audience for a starting point? • Have a shopping list: • Concerns ( • Time concepts (instant, duration, increment, periodic) • Analysis connections (convergence, characteristic time)
