STARLINK : WORLD'S MOST ADVANCED BROADBAND INTERNET SYSTEM
Starlink internet works by sending information through the vacuum of space, where it travels much faster than in fiber-optic cable and can reach far more people and places.
While most satellite internet services today come from single geostationary satellites that orbit the planet at about 35,000km, Starlink is a constellation of multiple satellites that orbit the planet much closer to Earth, at about 550km, and cover the entire globe.
Because Starlink satellites are in a low orbit, the round-trip data time between the user and the satellite – also known as latency – is much lower than with satellites in geostationary orbit. This enables Starlink to deliver services like online gaming that are usually not possible on other satellite broadband systems.
LESS MASS, MORE COMPACT
Each satellite features a compact, flat-panel design that minimizes volume, allowing for a dense launch stack to take full advantage of the launch capabilities of SpaceX’s Falcon 9 rocket.
Autonomous Collision Avoidance
Starlink satellites autonomously maneuver to avoid collisions with orbital debris and other spacecraft. This capability reduces human error and provides exceptional reliability, exceeding the industry standard by an order of magnitude.
Starlink’s custom-built navigation sensors survey the stars to determine each satellite’s location, altitude, and orientation, enabling precise placement of broadband throughput.
Optical Space Lasers
Starlink is testing fully operational, optical space lasers (Optical Intersatellite Links or ISLs) on its satellites, which allow the spacecraft to transmit data without local ground stations, providing truly global coverage.
Each Starlink satellite uses 4 powerful phased array antennas and 2 parabolic antennas to provide increased capacity.
ION Propulsion Systems
Efficient ion thrusters, powered by krypton, enable Starlink satellites to orbit raise, maneuver in space, and deorbit at the end of their useful life. Starlink is the first krypton propelled spacecraft ever flown.
Singular Solar Array
Starlink satellites feature a single solar array, significantly simplifying the system. Solar cells are standardized, and easy to integrate into the manufacturing process.
