About
NorthStar Earth and Space is a pioneering commercial space data company headquartered in Montreal, Canada. It operates the first-ever space-from-space monitoring service, leveraging a dedicated constellation of satellites with high-fidelity optical sensors to generate a secure, data-driven 3D catalogue of the entire space environment. This approach provides a level of precision, richness, and timeliness in space object tracking that ground-based systems cannot match. NorthStar's Space Data Services accurately track and predict the positions of satellites, debris, and other space objects — delivering collision avoidance alerts, space traffic management tools, and navigation services tailored for the New Space Economy. Its Earth Data Services platform supports users and communities in the sustainable management of Earth's natural resources through Earth observation analytics. Trusted by commercial satellite operators and government agencies, NorthStar's solutions support critical missions, regulatory compliance, and operational excellence in space. The company's SSA analytics infrastructure is designed to scale alongside the rapid growth of mega-constellations and new satellite deployments, addressing the urgent safety challenges posed by orbital congestion and space debris. With partners including KinetX Aerospace, Telespazio, Thales Alenia Space, SpecTIR, and ExoAnalytic Solutions, NorthStar is building foundational infrastructure for future space governance — making space a peaceful, safe, and sustainable environment for all stakeholders.

- Collision Avoidance & Space Traffic Data: Delivers timely, precise space traffic data and collision avoidance alerts to help satellite operators safely navigate increasingly congested orbital regimes.
- 3D Space Object Catalogue: Maintains a secure, high-fidelity, data-driven 3D catalogue of all tracked space objects and events, powered by advanced SSA (Space Situational Awareness) analytics.
- Earth Data Services Platform: A data-driven platform providing Earth observation products to support the sustainable management of natural resources, accessible to diverse user communities.
- Regulatory Compliance Support: Services are designed to support critical missions, operational excellence, and regulatory compliance for commercial operators and government agencies worldwide.
Use Cases
- Satellite collision avoidance: operators receive precise conjunction alerts to maneuver satellites away from potential collisions with debris or other spacecraft.
- Space traffic management: government agencies and regulators use NorthStar's 3D space catalogue to monitor congestion in key orbital regimes and enforce safe separation rules.
- Mega-constellation operations: commercial operators managing large fleets of satellites use NorthStar's tracking data to ensure safe launches, deployments, and end-of-life deorbit maneuvers.
- Earth resource monitoring: environmental agencies and research institutions access Earth observation analytics through NorthStar's data platform to track deforestation, climate impacts, and natural resource depletion.
- Regulatory compliance: satellite operators use NorthStar's timely and precise data to demonstrate compliance with international space safety standards and spectrum coordination requirements.
Pros
- Pioneering Space-from-Space Coverage: NorthStar is the first commercial provider to monitor space from space, offering unmatched tracking precision and coverage compared to traditional ground-based systems.
- Trusted by Government & Commercial Operators: Established credibility with both government agencies and commercial satellite operators, making it a reliable partner for mission-critical space safety operations.
- Comprehensive SSA Analytics: AI-powered analytics combined with a full 3D catalogue of space objects provide actionable intelligence for collision avoidance and space traffic management at scale.
- Dual Earth & Space Data Offering: Uniquely combines space situational awareness with Earth observation data services on a single platform, serving a wide range of industries and use cases.
Cons
- Enterprise-Focused Pricing: Services are designed for commercial satellite operators and government agencies, making costs likely prohibitive for smaller organizations or individual researchers.
- Limited Public Pricing Transparency: Detailed pricing information is not publicly available, requiring direct engagement with NorthStar's sales team to understand costs.
- Constellation Still Scaling: As a relatively new commercial service, the satellite constellation is still expanding, which may limit coverage density or data refresh rates compared to a fully deployed system.
Frequently Asked Questions
What makes NorthStar different from existing space tracking services?
NorthStar is the first commercial service to monitor space from space using a dedicated satellite constellation with optical sensors. Unlike ground-based radar systems, this approach provides a more complete, precise, and timely view of the orbital environment, particularly for small debris and objects in challenging orbits.
Who are NorthStar's primary customers?
NorthStar serves commercial satellite operators, constellation managers, and government space agencies that require reliable space situational awareness, collision avoidance services, and space traffic management data to operate safely in orbit.
What is Space Situational Awareness (SSA)?
SSA refers to the ability to accurately track and predict the positions and trajectories of all objects in space — including operational satellites, defunct spacecraft, and debris. NorthStar uses AI-powered analytics and its own satellite sensors to deliver high-fidelity SSA data.
Does NorthStar provide Earth observation data as well?
Yes. In addition to its space monitoring services, NorthStar is developing an Earth Data Services platform that provides Earth observation data and analytics to support sustainable management of natural resources for governments, researchers, and commercial users.
Is NorthStar publicly traded?
As of April 2026, NorthStar has announced plans to become a publicly traded company, expanding its ability to invest in its satellite constellation and data services platform.
