Kuiper

Project Kuiper is an initiative by Amazon to provide global broadband access through a constellation of 3,236 satellites in low Earth orbit (LEO). The system is designed to bring fast, affordable broadband to unserved and underserved communities around the world. It combines a LEO satellite constellation with customer terminals, a global network of ground stations, and resilient communications infrastructure powered by Amazon Web Services (AWS) to provide high-speed, low latency broadband on a global scale. The name "Kuiper" was inspired by the Kuiper Belt, a region of the solar system beyond the eight major planets. The project is expected to begin providing service to customers by the end of 2024. Amazon has also successfully validated key technology, including "optical inter-satellite links" (OISL), which will increase throughput and reduce latency for customers using its satellite communication tech.

Orbits and Constellation

  • The constellation is planned to consist of 3,236 satellites operating in 98 orbital planes in low Earth orbit (LEO) at altitudes between 590 and 630 kilometers (about 367 and 392 miles).
  • The satellites will be launched in multiple phases, with the first phase deploying 578 satellites at 630 km altitude and an orbital inclination of 51.9 degrees.

 

Spectrum (Frequency and Bandwidth)

  • The Kuiper satellite constellation will operate in the Ka-band radio frequencies, specifically in the 26.5-40 gigahertz range.
  • The satellites will provide internet service with a top speed of 100 megabits per second for residential and enterprise customers, and the terminals will link to satellites in low Earth orbit at altitudes between 590 and 630 kilometers
