NewSpace Market · Sector Catalogue
Every unit we list in this sector — specifications, manufacturers and where to ask for a quote. Compiled from the live NewSpace Market catalogue.
About this catalogue
This catalogue lists 57 star trackers products offered by 25 manufacturers across 13 countries. Of those, 26 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 August 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.
