Inter-Satellite Links: How Orbital Networks Move Data Without Coming Home First

Sun, 17 May 2026 00:00:00 +0000

A satellite constellation can look like a set of individual machines passing over Earth one after another. In practice, the most capable constellations begin to behave more like moving networks. The satellites are still spacecraft, with batteries, radios, computers, thermal limits, pointing constraints, and finite lifetimes. But when they can talk to one another, they are no longer only collectors or repeaters waiting for the next ground contact. They can pass traffic across orbit, route around gaps, and sometimes deliver data through a satellite that is hundreds or thousands of kilometers away from the place where the data began.
