3. Parameters for Event and Context Definitions  Geometry  Distance (body-body)  Rectangular Position (x,y,z of a body to another)  Geodetic Position (lat,lon,alt of a body to another)  Sub-point Position (lat,lon of a body’s subpoint over another)  Angle Separation (angle between 3 bodies)  Right Ascension & Declination (RA,DEC of a body to another)  Occultations  Region Of Interest (when a body flies over a squared area on the Surface of another body)  Sub-point Angles (Phase, Incidence, Emergence, Elevation, co-Elevation, …) *SPICE Toolkit N66  Landmark Angles (Phase, Incidence, Emergence, Elevation, co-Elevation, …) *SPICE Toolkit N66  External Events  From Science models: e.g. magnetosphere field crossings, …  From Operational aspects: e.g. EVTF, WOLs,...  Any other  Extra:  Generic Planning periods (MTP, CP, etc)  Fixed Time Steps (minutes, hours, days, day of the week, weeks, etc)  Time related (UTC, Julian, etc)  Counters 3
