Open-source avionics for sounding rockets
🐈 Always land on your paws! 🐈‍⬛

Website · User Manual · Downloads · Shop · Discord

We build open-source flight computers and ground systems for sounding rockets, with tools to configure missions, follow live telemetry, and analyze recorded flights. Our hardware designs and source code are available here to explore, modify, and contribute to.

The CATS Platform

  • CATS Vega: Flight computer combining configurable recovery and mission events, onboard logging, and GNSS telemetry.
  • CATS Ground Station: Handheld receiver for live flight monitoring and locating your rocket after landing.
  • CATS Configurator: Desktop application for configuring Vega, reviewing the flight sequence, updating firmware, and working with flight logs.
  • CATS Flights: Browser-based tools to analyze flight logs and explore flights shared by the community.

Repositories

Repository Contents
cats-embedded Firmware for Vega, the Ground Station, their telemetry modules, and user manual sources.
