Thought this should probably have its own thread now.

Amazon tested laser links with its Kuiper prototype satellites, maintaining a connection of 100 Gbps across multiple tests.

The company plans to include optical inter-satellite links from the outset in production satellites launching next year:

Project Kuiper: Amazon's Satellite Internet to compete with Starlink

Dec 12, 2023
Amazon's Project Kuiper will provide internet service via 3,236 satellites, competing with SpaceX Starlink and others. The October 6 test launch was declared a success, so deployment will start in 2024. The system is compared to Starlink, considering issues such as the apparent lack of inter-satellite links at least in the initial phases. Also, Amazon finally contracted for 3 Falcon 9 launches. If more are purchased, that could help it meet its difficult goals of launching enough satellites to keep its license. At a minimum, the 3 launches should relieve pressure from a shareholder lawsuit and potential challenges if a deadline extension is needed. Now, every active Starlink competitor does or will use SpaceX launches!

Project Kuiper update! Another batch of production satellites for our low Earth orbit internet constellation is on its way to Cape Canaveral, FL. These satellites, built to withstand the harsh conditions of space and the journey there, will be processed upon arrival to get them ready for launch.

Before shipping these satellites, we put each one through a series of tests that include:

Performance testing in a vacuum chamber to replicate outer space
Vibration and acoustic testing to simulate rocket launch conditions
Thermal heating and cooling cycles that simulate temperature changes the satellites will experience in space

These satellites will bring fast, reliable internet to customers even in remote areas. Stay tuned for our first launch this year.

The first production satellites for Amazon's Kuiper broadband network launched earlier this week, but if you tuned in to the mission's official livestream, the truncated coverage had the feel of a spy satellite launch.

This changed with a video Amazon posted on social media Friday, giving space enthusiasts and prospective Kuiper customers their first look at the real satellites. The 40-second clip shows the Kuiper satellites separating from their launch vehicle in the blackness of space following liftoff Monday from Cape Canaveral Space Force Station, Florida.

Since Amazon unveiled Project Kuiper in 2019, officials at the retail giant have been shy about showing even the most basic imagery of their satellites. Images released by Amazon previously provided glimpses inside the company's satellite factory near Seattle, along with views of the shipping containers Amazon uses to transport spacecraft from Washington their launch base in Florida.

Pretty much every Amazon project starts with a code name. Echo was “Doppler,” our first Kindle was “Fiona,” and our EC2 network device project was “Blackfoot,” after the penguins our AWS team saw while doing the work in Cape Town.

For our satellite network, it was “Project Kuiper,” and today, we’re introducing the permanent name: Amazon Leo—for the low Earth orbit (or LEO) constellation that powers the whole thing.

Team’s made lots of progress (150+ satellites up, >1 Gbps speeds, customers signing on) and am excited for the difference @Amazonleo will make for the ~500 million households, and millions of enterprises, orgs, and governments who need it

Amazon Leo debuts new gigabit-speed 'Ultra' antenna, begins enterprise preview [Nov 24]

Amazon revealed the final production design of Amazon Leo Ultra, an advanced, enterprise-grade terminal that delivers best-in-class performance for demanding private and public sector applications. The full-duplex phased array antenna provides download speeds of up to 1 Gbps and upload speeds up to 400 Mbps, making it the fastest commercial phased array antenna in production.

Leo Ultra is engineered for the elements with a durable, weather-resistant design that can withstand high-and low temperatures, precipitation, and strong winds. Its sleek and integrated design eliminates moving parts while enabling rapid installation and reliable operation across a wide range of locations.

The antenna is powered by a custom silicon chip designed by Amazon Leo and incorporates Amazon's proprietary radio frequency (RF) design and signal processing algorithms that maximize throughput while minimizing latency—critical factors for applications like video conferencing, real-time monitoring, and cloud computing. Leo Ultra also features advanced networking capabilities, including simultaneous upload and download capabilities and seamless integration with existing enterprise network infrastructure.

Amazon Leo will offer enterprise-grade features including easy-to-use network management tools, advanced encryption across the network, and 24/7 priority customer support. The service is designed to support critical business applications including real-time data processing, remote operations management, and secure communications for teams working in field locations. It also connects directly to Amazon Web Services (AWS), as well as other cloud and on-premise networks, allowing customers to securely move data from remote assets to private networks without touching the public internet. Amazon Leo will offer two primary private networking solutions:
• Direct to AWS: With Direct to AWS (D2A), AWS customers can connect directly to their cloud workloads using an AWS Transit Gateway or AWS Direct Connect Gateway through a point-and-click interface on the Amazon Leo web console, simplifying network management and lowering latency.
• Private Network Interconnect: Enterprises and telecommunications providers can also establish private network interconnects (PNI) at major colocation facilities to connect remote locations directly to their data center or core network, enabling Private Networking in days rather than the weeks or months typically required to deploy traditional private circuits.
