ARGO 2.0 multicamera star tracker

A legacy development reference within the ARGO technology path.

Legacy of ARGO SA

The star tracker ARGO 2.0 intends to be a smart redesign of the ARGO 1.0 architecture, targeting a further reduction of mass and power consumption while keeping performances as close as possible to the current architecture.

It also targets seamless integration with platform control, assuring high stability and maneuverability for microsat platforms. A drastic SWaP reduction makes the solution suitable for future large constellations.

  • Multiple optical heads including pre-processing software.
  • Data fusion software partially embedded in the Satellite Onboard Computer.
  • Optional Data Processing Unit for up to three optical heads.
  • Outputs include attitude, angular speed, angular acceleration and updated calibration models.
