HAWTHORNE, Calif. — SpaceX has become the first commercial company granted enhanced access to the U.S. Space Force's High Accuracy Catalog, the military's most precise database of objects in orbit, in a data-sharing arrangement that deepens the ties between the private launch leader and the Pentagon.
Under the agreement, the Space Force is giving SpaceX expanded access to the catalog, which tracks satellites and debris with far greater fidelity than the public data most operators rely on. In exchange, the military gains a steady feed of observations gathered by sensors riding on SpaceX's vast Starlink network, a two-way exchange that could sharpen space situational awareness for both sides.
Why the Catalog Matters
The High Accuracy Catalog is a closely held resource. Precise orbital data lets operators plan maneuvers, avoid collisions and keep crowded orbital shells safe as the number of active satellites climbs into the tens of thousands. SpaceX, which already operates by far the largest satellite constellation ever flown, has an obvious stake in keeping those lanes clear.
By tapping the catalog directly, SpaceX can fold the military's best tracking into its own automated collision-avoidance system, which already commands thousands of Starlink spacecraft through autonomous maneuvers. The result should be fewer conjunction warnings and a smoother path as the company scales toward its next generation of larger, higher-bandwidth satellites.
A Sensor Network in Orbit
The reciprocal half of the deal may prove just as valuable. Starlink's spacecraft blanket low Earth orbit, and sensors distributed across that fleet can function as a distributed observation grid, spotting and timing objects from vantage points no single ground station can match. Feeding those observations back to the Space Force gives the military a richer, more current picture of the orbital environment.
