APPENDIX E DELIVERY FORMAT OF SEPARATION STATE VECTOR PRE-LAUNCH EXAMPLE SpaceX OPM output (generated YYYY-MM-DD-Day-HH-MM-SS):
All orbital elements are defined as osculating at the instant of the printed state. Orbital elements are computed in an inertial frame realized by inertially freezing the WGS84 ECEF frame at time of current state. This OPM is provided based on flight telemetry
from the second-stage, and therefore represents the state of the second-stage and not the state of any other body. Any position,
velocity, attitude, or attitude-rate differences between the second-stage and any other body need to be accounted for by the recipient of this OPM. UTC time at liftoff DOY:HH:MM:SS.SS
