Elon Musk’s SpaceX unveils ‘Stargaze’ to track thousands of satellites in real time

SpaceX has introduced a new system for tracking what is going through low Earth orbit and how close those items are to each other. Instead of depending just on ground-based radar, the technology known as Stargaze collects data from thousands of existing satellites in space. According to the corporation, the technology can detect changes in satellite motion more faster than current systems, reducing the chance of crashes. SpaceX intends to share Stargaze screening data with other satellite operators at no cost in the coming weeks. The decision comes as orbital congestion worsens due to satellite launches, uncoordinated movements, and mission debris. Long-time industry analysts have cautioned that traditional tracking methods are unable to catch up.

Free SpaceX Stargaze data encourages coordination among operators

SpaceX plans to make Stargaze conjunction screening available to all operators at no cost. The platform has already been tested in a closed beta with more than a dozen satellite operators. Participants can share ephemeris data and receive low-latency screening results. From spring onwards, operators who submit trajectory predictions will receive alerts based on Stargaze data alongside information shared by other participants.

Growing congestion increases pressure on tracking systems

Low Earth orbit has become increasingly crowded. Old rocket bodies remain in place long after missions end. Some operators adjust satellite paths without sharing updated trajectories. Military tests have also added fragments that move unpredictably. Many existing tracking systems observe objects only a few times per day, leaving wide gaps between updates. Those gaps grow larger when space weather interferes, making predictions less certain just when accuracy matters most.

Stargaze expands detection using satellites already in orbit

Stargaze takes a different approach. SpaceX says the system draws on data from nearly 30,000 star trackers already flying across its satellite fleet. Each tracker makes continuous observations of nearby objects. Together, they produce roughly 30 million detected transits every day. This creates a dense and constantly refreshed picture of activity in orbit, rather than periodic snapshots from the ground.

Near real-time screening shortens reaction windows

Observations collected by Stargaze are processed automatically. The system builds updated estimates of position and velocity for detected objects and feeds them into a space traffic management platform. Potential close approaches are flagged and Conjunction Data Messages are generated within minutes. SpaceX says this is a significant improvement over current industry timelines, which often take several hours to deliver similar warnings.

A late 2025 encounter highlights the Stargaze system's response

SpaceX points to a close approach in late 2025 as an example of the system’s value. A Starlink satellite encountered a third-party spacecraft that was manoeuvring without sharing ephemeris data. Initial projections showed a wide miss distance. Five hours before the encounter, a manoeuvre sharply reduced that margin. Stargaze detected the change quickly, updated the trajectory, and distributed new warnings. The Starlink satellite was able to plan and execute an avoidance manoeuvre within an hour.
