Space Traffic Coordination APIs

Collision Avoidance Screening

The APIs hosted at provide a means for satellite operators to submit ephemeris files for screening against the Starlink constellation.

Screening results are available in minutes and can be ingested into Starlink's autonomous collision avoidance system.

Starlink states are updated in the system roughly every 30 minutes.

Maneuver Coordination

Starlink is developing experimental APIs for managing maneuver coordination between operators as part of a collaboration with NASA's Ames Research Center. Contact for more information.

Sign Up

Currently, use of the API is limited to satellite operators. Contact for more information.

This inbox is monitored during business hours. To contact Starlink collision avoidance operators 24/7 for conjunction coordination, see our Satellite Operators page at
