From advanced research to operational capability.

When GPS fails and comms drop, autonomy has to hold.

Sigma Bridge works with aerospace and defence teams to keep autonomous systems dependable in the conditions that matter most.

What we do

Autonomy Advisory

Designing and assessing autonomous systems that stay dependable when GPS is denied or communications are lost.

AI Decision Systems

Understanding why systems behave the way they do, so decisions hold up in the field, not just in a demo.

Defence Procurement Navigation

Helping Canadian innovators find their path into defence procurement, from capability to opportunity.

About Sigma Bridge

Sigma Bridge is a Canadian aerospace and defence advisory, based in Ottawa. We work on the problems that decide whether systems keep working when conditions turn against them: in flight, in contested airspace, in the Arctic, and one day, beyond.

Aerospace

Flight systems that stay dependable from takeoff to touchdown, for crewed and uncrewed flight.

Defence

Autonomy and decision systems for operations where signals can't be trusted, plus independent QA/QC and technical review for defence programs.

Exploration

Mission support and consulting for high-risk Arctic and remote operations, where resupply, repair, and rescue are days away.

CELSS

Closed ecological life support systems: a long-horizon research interest for remote outposts and, one day, deep space.

Founder

Charles A. Berube, President and CEO.
