The story
Laser Crosslinks and a More Connected Constellation
Starlink v1.5 advanced the network with upgraded spacecraft capabilities, including wider use of inter-satellite laser links.
This page connects the Starlink tracker to the engineering history behind the spacecraft users see moving across the globe.
Mission design
Built as part of a large low-Earth-orbit network
Starlink is not a single spacecraft mission. It is a constellation architecture in which many satellites, launch campaigns, ground systems, and user terminals operate together.
That makes each generation useful for explaining how satellite design changes as a network scales and its goals expand.
Why it matters
A step in the evolution of satellite internet
This generation or experiment represents a distinct step in the development of Starlink technology.
Following these pages in sequence lets TransitSatellite users see how a modern constellation evolves through prototypes, operational generations, engineering experiments, and new communications capabilities.
