Starlink's plan to avoid orbital near-misses: Ephemeris sharing

The surge stems from SpaceX’s own disclosure that its 11,000‑satellite network experiences hundreds of close approaches annually. Undisclosed maneuvering has been identified as the biggest threat, while the growing density of active satellites intensifies collision probability. SpaceX has publicly warned that the crowding of Earth's orbit could jeopardise operational reliability.

The company’s warning aligns with reports that densely packed orbits increase the chance of cascade collisions, known as Kessler syndrome. In response, SpaceX proposes sharing precise orbital ephemerides so other operators can avoid intersecting paths, a plan outlined by The Register. Aerospace Global News cited the company’s call‑out of rival operators whose trajectories have nearly intersected Starlink.

The approach aims to reduce surprise maneuvers, but it leaves open how industry‑wide data standards and trust will be established. Industry observers will watch whether the data exchange gains traction among the dozens of emerging constellations planning launches through 2030.
