Level 0.3/0.5 • Level 0.3 is the Quicklook data product. It is not a final product, but rather a fast, “best estimate so far” product. • Level 0.3 combines : • The image • Image status packet • Mech table lookup values • Selected telemetry from the Sequencer & Thermal data packets • Flight Dynamics orbit information • Selected telemetry from the Space Vehicle’s Ancillary Science Data packet • Selected commanding data used to interpolate likely positional values of the instrument • Level 0.3 is expected as Quicklook data a few minutes after receipt of telemetry • Level 0.5 is the final product of the above elements. It includes all actual positions, orbits, velocities and telemetry. Used for Level 1 data. • May be 1-2 days (or more in unusual cases) to finalize Level 0.5
SDO Spacecraft Housekeeping • In the Ancillary Science Data Packet • Includes: Eclipse flags, best estimate of attitude quaternion, quaternion from inertial to sun • reference frame, ephemeris model time • Available in 24-hour dayfiles, and streaming in from the SOC via socket • Flight Dynamics System data • Covers orbit predictions and spacecraft position and velocities • Comes with several weeks’ worth of position predictions. Will be sent to us again if actual is • not within error tolerance of predicted position. • Available weekly for pickup • Commands • Needed for Quicklook products • Telemetry • Will include Image, Image Status Packet and Mech Table conversions as Level 0.1 • Still need to determine which telemetry of the Sequencer and Thermal packets to include • Final telemetry list will be largely determined by the Level 1.5 product - still in development • Other space vehicle telemetry may also be required beyond the ASDP.
