Amazon’s Kuiper low Earth orbit (LEO) satellite tv for pc community handed a major milestone when its two orbiting satellites had been capable of talk with one another at excessive information switch speeds utilizing Optical Inter-Satellite Link (OISL) expertise, the corporate revealed final week.
OISL is a key element of Kuiper’s mesh structure, which makes use of infrared lasers to ship information between satellites. According to Amazon, it was capable of preserve a steady connection between the 2 prototype satellites at a knowledge switch velocity of 100 gigabits per second (Gbps) and a distance of 621 miles.
These exams validated the ultimate element of Project Kuiper’s superior communications structure, and the outcomes be certain that OISLs can be operational on our first manufacturing satellites, slated for launch within the first half of 2024, the corporate acknowledged on its on-line information website.
“With optical inter-satellite links across our satellite constellation, Project Kuiper will effectively operate as a mesh network in space,” Project Kuiper’s Vice President of Technology Rajeev Badyal stated in an announcement.
By making a mesh community in house, Amazon defined that will probably be capable of enhance throughput and cut back latency throughout the Kuiper constellation and supply customers of the community extra flexibility to connect with it throughout land, sea, air, and house.
“Satellite-to-satellite communication is where there’s often a bottleneck,” stated Peter Chahal, community and telecommunications analysis director at IDC, a world market and analysis agency.
“By having this optical mesh, it will allow Amazon to address latency issues,” he informed TechNewsWorld. “By having optical inter-satellite connectivity, it’ll maintain better performance and lower latency.”
Leveraging AWS
Amazon famous that one other good thing about utilizing OISLs is the velocity at which information might be moved all over the world. Light travels quicker in house than it does via glass, which signifies that Kuiper’s orbital laser mesh community can switch information roughly 30% quicker than if it traveled the equal distance through terrestrial fiber optic cables, it defined.
Project Kuiper can even profit from Amazon’s AWS service and infrastructure. “Not only does Amazon have OISL between satellites, but it will have ground stations in close proximity to Amazon data centers so it can maintain low latency and high performance on the network from space to the terrestrial ground stations,” Chahal stated.
Compared to Elon Musk’s SpaceX Starlink LEO satellite tv for pc community, which makes use of a point-to-point structure, Kuiper may be very complicated. To preserve the energy of the laser hyperlinks within the system, gentle unfold must be minimized over distances as much as 1,616 miles. Then, the connection must be maintained between spacecraft shifting at speeds of as much as 15,534 miles per hour — and all of that must be achieved whereas compensating for satellite tv for pc and flight dynamics.
The payoff to all that complexity, Amazon maintains, is the flexibility to maneuver and land information wherever through the house mesh community, bringing safe, resilient connectivity to a variety of the corporate’s enterprise and public sector clients.
This functionality is very necessary for patrons working in areas and not using a close by floor station, equivalent to a cruise liner in the midst of the ocean or an plane making a transatlantic flight, Amazon defined, whereas permitting them to securely uplink information from successfully any location on Earth, transmit it via house through laser communications, and downlink it to their vacation spot of selection.
Good November for Kuiper
“Amazon’s optical mesh network will provide multiple paths to route data through space, creating resiliency and redundancy for customers who need to securely transport information around the world,” Kuiper Government Solutions Vice President Ricky Freeman stated in an announcement.
“This is especially important for those looking to avoid communications architectures that can be intercepted or jammed,” he continued, “and we look forward to making these capabilities available to public sector customers looking to move and land data from remote locations to their desired destination.”
Amazon’s disclosure of its OISL success capped a sequence of milestones Kuiper achieved in November.
“Successful tests have showcased the first two-way video call, Ultra HD 4K video streaming from Amazon Prime Video, and the first-ever Amazon.com purchase conducted over Amazon’s Kuiper SatCom network,” Analyst Victor Xu wrote in a report for ABI Research, a world expertise intelligence agency.

“These tests have validated all systems and subsystems on board Project Kuiper’s prototype satellites,” he continued, “and have marked a substantial step forward for the Kuiper mega-constellation, which is a planned constellation of 3,236 low Earth orbit satellites.”
He added that ABI anticipated that the worldwide satellite tv for pc broadband market will generate service revenues of about US$18.5 billion by 2030, representing a 13.9% compound annual development charge (CAGR) from 2022 to 2030.
“The future of delivering the Internet will look very different from what we have been using,” stated expertise analyst Jeff Kagan.
“Satellite internet connectivity will play an increasingly important role in society,” he informed TechNewsWorld. “It will deliver service to areas that have none, and it will offer a competitive choice in areas where there are limited options.”
Bezos Burger Bar
Successes apart, Kuiper nonetheless has an extended approach to go to catch as much as Starlink, which already has 5,420 satellites orbiting the Earth. “You could say that Jeff Bezos and Elon Musk share the same dream; the difference is that Elon Musk has already delivered what Jeff Bezos dreams of,” John Strand, of Strand Consult, a consulting agency with a deal with telecom, in Denmark, informed TechNewsWorld.
“Jeff Bezos has opened his first burger bar. Elon Musk owns McDonald’s,” he quipped.
“If you look further down the road, Starlink has the advantage,” he stated. “They have access to cheap lifting capacity — the capacity that is the foundation for setting these satellites up in space.”
He added that Starlink’s quantity of satellites offers it an edge not solely in house however on the bottom, too. “When you look at the regulatory challenges that affect this industry, Starlink’s volume will make it be seen by the authorities in many countries as an important alternative provider of vital infrastructure,” he stated. “This gives them better access to national regulators.”
“It’s great that Amazon is developing and trying new technology,” he continued. “Competition is healthy for the market, but I don’t think Kuiper is something that’s spoiling the sleep of the folks at Starlink.”
