34,000 ACTIVE SPACE OBJECTS
Contested and congested orbits threaten human space activity.
The exponential growth of satellites, spacecraft, launches, manoeuvres, and debris is reshaping the near-Earth environment.
NorthStar’s Space Situational Awareness (SSA) and Space Domain Awareness (SDA) services identify what’s there and how it’s moving, essential to operating safely and effectively in space.
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.

01 DETECT
Space Object Tracking
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.
- Passive Collection
-
Our sensors continuously scan for objects without requiring a predefined target, detecting new and previously unknown objects.
- Tasked Data Acquisition
-
Direct NorthStar’s space-based sensors toward specific objects when targeted tracking data is needed across LEO, MEO, and GEO.
- Customer-Supplied Imagery Processing
-
Turn customer-supplied raw sensor imagery into usable tracking data by calibrating observations, detecting objects, measuring their positions, and correlating them against known objects.
- Ground-Based Collection
-
Generate tracking data using NorthStar-managed ground-based optical systems, providing an additional source of observations across orbital regimes.
02 UNDERSTAND
Space Object Information
Turn observations into understanding.
NorthStar combines multi-source observational and orbital data to characterize objects in space. Our analytics reveal how they move, how they behave, and when that behavior changes.
- Automated Data Curation, Fusion & State Vector Generation
-
Combine observations from NorthStar, customer, and third-party sensors (including optical, radar, and RF sources) to generate state vectors and a more reliable picture of an object’s trajectory.
- Collision Awareness & Avoidance
-
Continuously screen protected satellites against the space-object catalogue to identify close approaches and potential threats. Assess factors including miss distance, conjunction geometry, and probability of collision.
Once a risk has been identified, consider potential avoidance maneuvers, accounting for operational constraints such as propulsion limits or fuel budget.
- Launch & Early-Orbit Risk Assessment
-
Analyze launch windows for potential collision risks, and observe newly launched objects while their trajectories are still developing. This service also supports the identification of potentially malicious launches.
- Maneuver Detection & Early Classification
-
Notice when an object deviates from its expected trajectory. Using observational and orbital data, detect potential maneuvers, and characterize behavioral changes.
- Photometric Pattern-of-Life Analysis
-
Establish a pattern in an object’s observed brightness and detect variations from that baseline. Those shifts can indicate attitude changes or potentially adversarial activity.
