Defense Intelligence Reference Document Cockpits In The Era Of Breakthrough Flight

UNCLASSIFIED//F811. 8FFll!l*L 1!1!11! l!IIU:!Y
• Navigational information sources:
- Position:
■ Master reference taken relative to starting position (Sun-Earth system).
• Current location taken from the following:
o Star tracker:
• Modified to handle 3D database of star locations for deep-space
motion (yet less than 100-light-year radius around the Sun).
• Predictive trajectories (to extrapolate positions for FTL travel).
• Note: Can only take star tracker readings at sublight speed.
o First integration on measured velocity and relative to point of
departure.
o Second integration on measured accelerations since point of departure.
- Velocity:
■ Directly measured from cosmic microwave background Doppler shifts,
where velocity is relative to the mean rest frame of the universe.
■ First integration on measured accelerations since point of departure.
- Accelerations:
■ Linear:
o Accelerometers with corrections calculated based on the influence of
the propulsion methods that affect gravitational and inertial forces.
o Differentiation of velocity changes as measured using the cosmic
microwave background.
■ Rotational:
o Gyros (e.g., ring laser gyros) with correction inputs from the
propulsion methods that affect gravitational and inertial forces.
o Orientation as inferred from star tracker measurements.
