XNAV for Deep Space Navigation

Abstract: The concept of utilizing pulsars for spacecraft navigation has been in development since the discovery of these rapidly rotating neutron stars in the 1960’s [1]. The Jet Propulsion Laboratory (JPL) conducted studies in the 70’s and 80’s proposing the use of...

Autonomous On-board Orbit Control: Flight Results and Cost Reduction

Abstract: Microcosm, under Air Force Research Laboratory (Space Vehicles Directorate) and internal funding, developed and flew the first fully autonomous, on-board orbit determination and in-track and cross-track control system. Results show the technology maintaining...

Applications of Autonomous On-Board Orbit Control

Abstract: Fully autonomous, on-board orbit control was flight demonstrated on UoSAT-12. This technology was developed to reduce operations cost. It does this using less propellant than traditional orbit maintenance, but also opens a new array of potential mission...
