What is Amazon Kuiper?
Project Kuiper is Amazon's planned LEO satellite broadband constellation, authorised by the FCC in July 2020 for up to 3,236 satellites in orbits ranging from 590 to 630 km altitude. Named after the Kuiper Belt of icy bodies beyond Neptune, the project is Amazon's answer to SpaceX Starlink — competing for the global satellite broadband market estimated at hundreds of millions of underserved customers.
Technical design
Amazon has been tight-lipped about satellite specifications, but FCC filings indicate satellites operating in Ka-band with aggressive power and frequency reuse architectures. The constellation uses three altitude shells: 590 km (784 satellites), 610 km (1,296 satellites), and 630 km (1,156 satellites). Amazon designed its own customer terminals — including a compact flat-panel unit targeting cost below $400 — and its own proprietary satellite modem chipsets, suggesting a vertically integrated approach similar to SpaceX's. Ground gateways will integrate directly with Amazon Web Services (AWS) infrastructure.
Launch strategy and timeline
Amazon secured launch capacity from multiple providers: United Launch Alliance Vulcan Centaur, Arianespace Ariane 6, and its own Blue Origin New Glenn rockets. Initial prototype launches began in 2023 with engineering test satellites. Commercial service pilots began in late 2024 with a small customer beta. FCC licensing requires Amazon to deploy at least 1,618 satellites (50% of the constellation) by July 2026 and the full constellation by 2029. The project represents an estimated $10+ billion capital investment.
