 delta DOR  Track spacecraft simultaneously  Record quasar’s wavefronts  Triangulation yields spacecraft’s angular position Delta-DOR Principle « Arpsoft. and-services/delta-dor-readmore/

Trajectory Correction Maneuvers ◦ Compute vector required to correct the trajectory. ◦ Timing  Small change can be done immediately ◦ Rotate and use thrusters Delta-DOR Principle « Arpsoft. and-services/delta-dor-readmore/

Orbit Trim Maneuvers ◦ Adjusts  Instrument’s field of view  Sensitivity of gravity field  Prevent orbital decay ◦ Changes to either:  Periapsis – closest point  Apoapsis – furthest point Delta-DOR Principle « Arpsoft. and-services/delta-dor-readmore/
