Navigation Processing

Navigational processing requirements vary widely with each mission and are highly dependent on mission size and complexity. SDL has extensive experience with scaling appropriate navigational computation solutions to the mission size, complexity, and requirements.


  • Spacecraft position determination
    • On-orbit processing
    • Ground post-processing
    • Recursive filtering (least-squares, Kalman)
    • Rendezvous and proximity ops
    • Global Positioning Systems (GPS)
  • Spacecraft orbit planning
    • Orbit insertion
    • Orbit maintenance
    • End-of-life deorbit
    • Thruster design analysis
  • Angles-only navigation



Dynamic Ionosphere Cubesat Experiment

Twin CubeSats mapped the geomagnetic Storm Enhanced Density (SED) plasma bulge and plume formations in Earth’s ionosphere.


Auroral Spatial Structures Probe

ASSP was designed to measure the spatial and temporal variation of the energy flow in the upper atmosphere in and around the aurora to better understand global temperature changes in the thermosphere.
