Starlink Block v1.0

Starlink is SpaceX's 4425-satellite 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.

The initial, up to 75, satellites, called Block v0.9, are prototypes without inter-satellite links.

For launch, 60 satellites are stacked on top of each other without the need of a massive deployer. 60 satellite is the maximum possible to fit inside the Falcon-9 v1.2 (Block 5), although a future enlarged fairing will allow launches of more than 60 satellites per mission. Later satellites are also to be launched by the Super Heavy Starship reusable launch vehicle.

The first launch is planned for May 2019 on a Falcon-9 v1.2 (Block 5) booster, carrying 60 Starlink Block v0.9 prototype satellites for testing.

Two to six launches of each 60 fully operational Starlink Block v1.0 satellites are planned for 2019.
