The quality of our solutions is reflected in our exceptional flight heritage – the MOST microsatellite has exceeded performance specifications, continuing to operate normally on-orbit more than three times longer than expected. Our reaction wheels have over 75 years of on-orbit heritage without failure. This success has made us the reaction wheel builder of choice in Canada, and the premier provider of reaction wheels for microsatellites globally.
