SpaceX’ Starlink LEO satellite constellation

SpaceX Starlink LEO satellite constellation has been built since 2015 by SpaceX. The constellation provides satellite Internet access.  The constellation will consist of thousands of mass-produced small satellites in Low Earth Orbit (LEO), working in combination with ground transceivers. Starlink satellite constellation will deliver high speed broadband internet to locations where access has been unreliable, expensive or completely unavailable.

Each satellite weighs approximately 260kgs and features a compact, flat panel design that maximizes volume, allowing for a diverse launch stack on SpaceX Falcon 9 rocket. The total cost of the decade-long project to design, build and deploy the constellation was estimated by SpaceX to be about 10 billion USD.
