LeoLabs

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. Founded in 2016 and headquartered in Menlo Park, California, the company runs 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.

The radar network is the core asset, and 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 prior LeoGuard service. Companion services include Pulse for collision avoidance and Trace for launch and early-orbit tracking.

LeoLabs holds a SpaceWERX and US Space Force 60 million dollar STRATFI award (March 2025) to deploy a Seeker-class radar in the Indo-Pacific by 2027, along with contracts with the US Department of Commerce, the Space Force, and Japan's Air Self-Defense Force. Its space-domain and collision-warning outputs are probabilistic, its orientation is strongly national-security and dual-use, and its coverage is radar-geometry-dependent and focused on low Earth orbit.
