SpaceX has unveiled Stargaze, a new Space Situational Awareness (SSA) system that gives satellite operators free, precise tracking of objects in Earth
orbit.
The Elon Musk-owned rocket company is opening its conjunction screening service to the global space community to enhance satellite safety.
By providing free ephemeris sharing and conjunction screening, SpaceX aims to encourage satellite operators to adopt more transparent and safer orbital practices.
In a post on X, Musk wrote, "SpaceX is now providing precise positional awareness of objects in Earth orbit to all satellite operators for free. This will greatly reduce the probability of collisions that create orbital debris (space junk) hazards.”

SpaceX's newly unveiled Stargaze system uses nearly 30,000 star trackers on its satellites to detect approximately 30 million transits daily, significantly increasing detection capability for objects in low Earth orbit.
The Stargaze system autonomously aggregates observations to generate near real-time orbit estimates and predictions of position and velocity for detected objects.

These predictions are integrated into a space-traffic management platform, identifying potential close approaches between objects and generating Conjunction Data Messages. SpaceX created this system that can offer conjunction screening findings in minutes, instead of the industry standard of many hours.
SpaceX announced it will make its Stargaze conjunction data available to all satellite operators free of charge through its space-traffic management platform.
Apart from the ephemeris from other participating operators, operators who submit ephemeris (trajectory forecasts) to the platform will start receiving CDMs against Stargaze data starting this spring. This guarantees that operators have low-latency access to the best available data for conjunction assessment.
