Real time space domain awareness

NorthStar combines space-based sensing, data fusion, and advanced analytics to give operators a precise and timely picture of what’s happening in the space environment.

We help government and commercial operators detect and track objects, understand changes in activity, identify threats, and make informed decisions when it matters most.

Reducing risk in a soon-to-be trillion-dollar industry

Space is the front line of defence and a new frontier for building the infrastructure of the future, offering unprecedented possibilities for commerce and innovation.

Greater opportunities bring the need for better monitoring and security as our presence expands.

Monitoring 300 trillion km³ of space

High precision, always “On”, early warning

Space-based surveillance
Our space-based sensors address gaps in ground-based systems, improving coverage, revisit rates, data quality, and precision across LEO, MEO, and GEO orbits.
Harnessing multi-sensor data
We quickly detect orbit changes, maintain lock on countless space objects, and deliver real-time information and intelligence using a combination of ground-based and space-based imagery through our source-agnostic data processing pipeline.
From data to decisions
Detection is just the starting point. NorthStar’s patented architecture fuses and analyses diverse sources of data from multiple perspectives to create a timely and complete picture to support space operators to better understand orbital activity.
Proven in operation
NorthStar provides 24/7 mission-operational support to government, defence, and commercial customers globally, including work with DARPA, U.S. Space Force Joint Commercial Operations, and Canada’s Department of National Defence.

Scanning through space, from LEO to GEO

NorthStar’s space-based sensors scan continuously across near-Earth orbits, complemented by ground-based and partner observations to expand coverage and maintain custody of space.

Supporting our customers

For the realities of space today

Defence & national security

Stay ahead of emerging threats in space

As Space takes on a frontline role in national defence, better monitoring and security are becoming essential.

Monitor known and unknown objects, detect anomalous behaviour in real time, and identify potential threats to satellites supporting critical infrastructure, national security, and allied operations.

Civil & government

Safeguard the space-based infrastructure we all rely on.

Protect essential services like communications, environmental monitoring, and disaster relief. Get early warning of collisions and other unexpected events as they arise.

Commercial operators

Build what comes next in space.

Use reliable space data to develop new applications, launch new ventures, and operate in a rapidly growing space economy.

NorthStar recognizes that verifiable transparency into space activities ensures accountability necessary for a stable market economy from Space.
