About this catalogue
What is inside
This catalogue lists 61 star trackers products offered by 28 manufacturers across 15 countries. Of those, 33 carry a manufacturer datasheet and 4 publish a price; the rest are quoted on request — normal in this market, where configuration drives cost.
Entries are grouped alphabetically by manufacturer. Every product links back to its page on newspacemarket.com, where you will find the full specification, the datasheet and a quote form that reaches the manufacturer directly.
Compiled 15 October 2026 from the live catalogue. Specifications are as published by the manufacturers; we normalise units but do not re-measure. Where a figure looked implausible it was left out rather than guessed.
