Star trackers determine spacecraft attitude by matching an observed star field against an onboard catalogue. The table below compares the models listed on NewSpace Market by mass, power draw and envelope — the three figures that decide whether a unit fits a given bus.
Figures are taken from manufacturer datasheets and product pages, normalised to
common units. Every row links to the product page and, where available, to the
datasheet itself. As of 2026-10-15.
A dash means the figure is not published by the manufacturer.
For 1 model(s) an extracted value fell outside the plausible range for this class of hardware and is withheld pending manual checking, rather than shown as fact. Download the same table as CSV — free to reuse with attribution (CC BY 4.0).
