ISC Space Challenge: LEO Satellite Comms in Contested Environments ($2M)

Satellite communications are a prime target in modern conflict. DND's Innovative Solutions Canada space challenge funded up to $2 million per contract for resilient low-earth-orbit (LEO) satellite communications that use adaptive beamforming to counter adversarial interference — validated with real testbed performance data.

This round closed April 7, 2026. We're covering it because DND runs space challenges in recurring rounds, and the requirements are a clear signal of what the next one will want. If you build satcom or RF technology, here is what to be ready for.

What DND was looking for

Resilient LEO satellite communications capable of maintaining a link under adversarial interference, using adaptive beamforming to steer around jamming and interference. Critically, proposals had to be backed by performance measurements from testbed experiments — not just modelling.

Challenge details

How to be ready for the next round

DND's space and MINERVA challenges recur. If satcom is your space, the lesson from this challenge is clear: have testbed performance data ready, and be at TRL 5–9. We help Canadian space and defence companies monitor upcoming Innovative Solutions Canada challenges, prepare the evidence base in advance, and move fast when a relevant call opens — while funding the underlying R&D through SR&ED and NRC IRAP DI Assist.

Frequently asked questions

Is the ISC LEO satellite communication challenge still open?

No — this round closed on April 7, 2026. However, DND runs space and defence challenges in recurring rounds through Innovative Solutions Canada, so a similar future call is likely. Watch the ISC challenges page.

How much did it fund?

Up to $2,000,000 CAD per contract, with an estimated two contracts, over up to 12 months. It was a Phase-2 challenge at TRL 5–9.

What technology did it seek?

Resilient LEO satellite communications using adaptive beamforming to counter adversarial interference, validated with performance data from testbed experiments.

How do I prepare for the next one?

Have TRL 5–9 technology and testbed performance data ready, and monitor the Innovative Solutions Canada challenges page. We help companies stage the R&D (via SR&ED and DI Assist) so they can move quickly when a relevant call opens.
