Description:
- Starlink is SpaceX′s 4425-satellites low earth orbit constellation to provide broadband Internet access.
- The mass-produced spacecraft carry a communications payload using the Ku and Ka frequency bands. The satellites will employ optical inter-satellite links and phased
array beam forming and digital processing technologies.
- The Starlink satellites feature a flat panel design with a single solar panel and have a mass of about 227 kg. The satellites are stacked for launch without the
need for an dispenser. As a propulsion system for orbit adjustion and maintenance as well as deorbiting, they use krypton-fueled Hall thrusters. The Startracker navigation
system is based on the heritage of Dragon. The satellites are designed autonomously avoid collisions based on uplinked tracking data. At the end of life, the Starlink
satellites are to be actively deorbited, leading to reentry. 95% of the material is expected to burn up.
- The first 1584 Starlink satellites are to operate from a 550 km orbit. Later sub-constellations are planned for 1200 km and very low 340 km orbital altitude,
bringing the final constellation size to nearly 12000 satellites.
