Sagitta - Star Tracker

arcsec

Sagitta is arcsec’s standard star tracker. It is fully autonomous, fits in a CubeSat, has an integrated baffle and has an accuracy of 2 arcsec (1σ) cross-boresight and 10 arcsec (1σ) along-boresight.

You can further customize it with external baffles, extra coatings or mounting plates.

Sagitta can also detect space debris during the course of its operation and is eligible to participate in the DeDUST program.

Features:

  • Star tracking and attitude determination
  • Full image download capability
  • Image histograms
  • Fast lost-in-space algorithm

Performance:

  • Cross-boresight accuracy: 2" (1σ)
  • Around boresight accuracy: 10" (1σ)
  • Tracks stars up to magnitude 6.2
  • Tracks up to 64 stars
  • Update rate of 10 Hz
  • Field of view: 25.2°
  • Autonomous calibration

Robustness:

  • Lost-in-space availability: >99% of the night sky
  • Discards vast majority of false star instances
  • Autonomous detection and correction for outlier stars
  • Baffle sun rejection angle: 40°
  • Radiation shielded lens
  • Electronics are radiation tested
