- Assess the probabilistic-output, dual-use, and radar-geometry limits of space-tracking analytics
What Is LeoLabs Delta?
LeoLabs operates a worldwide network of ground-based phased-array radars that continuously track objects in low Earth orbit, maintaining an independent object catalog rather than relying on government data. The radar network is the core asset; the AI is the analytics layer that interprets what the radars see.
LeoLabs Delta, launched April 8, 2026, provides advanced AI threat detection and characterization for US and allied national-security missions, replacing the company's prior LeoGuard service. Alongside Delta, LeoLabs offers companion services: Pulse for collision avoidance and Trace for launch and early-orbit tracking. The company operates roughly 11 radar installations across seven global sites — including US locations in Alaska, Texas, and Arizona, plus New Zealand, Costa Rica, Australia, the Azores, and Argentina.
💡Key Concept
Independent radar tracking: Phased-array radars can scan the sky electronically, tracking many fast-moving objects at once without physically moving the antenna. LeoLabs uses a global network of them to detect and follow satellites and debris, building its own catalog. Delta then applies AI to characterize behavior and flag potential threats — a maneuvering satellite, a possible conjunction, or an object behaving abnormally.
Key Capabilities
- Global radar network — roughly 11 phased-array installations across seven sites track low Earth orbit continuously
- Independent object catalog — maintains its own tracking data rather than depending on government sources
- Delta AI threat detection — detects and characterizes threats for US and allied national-security missions
- Pulse collision avoidance — conjunction assessment and warning for satellite operators
- Trace launch tracking — supports launch and early-orbit object tracking
⚠️Warning
Concerns to weigh honestly. Space-domain and collision-warning outputs are probabilistic — conjunction and "threat" assessments carry genuine uncertainty and false-alarm tradeoffs, and acting on them means balancing the cost of a maneuver against the risk of ignoring a warning. LeoLabs has a strong national-security and dual-use orientation, which shapes what it monitors and for whom. Its coverage is radar-geometry-dependent and focused on low Earth orbit, so higher orbits are outside its core capability. As a private company, its financial transparency is limited.

Key Takeaways
- LeoLabs Delta is an AI threat-detection and characterization service built on a global ground-based radar network that maintains an independent catalog of objects in low Earth orbit
- The radar network is the core asset, with Delta, Pulse, and Trace layered on top for threat detection, collision avoidance, and launch tracking
- The honest caveat: conjunction and threat assessments are probabilistic with false-alarm tradeoffs, the orientation is strongly national-security and dual-use, and coverage is radar-geometry-dependent and focused on low Earth orbit
