Amazon’s Kuiper low Earth orbit (LEO) satellite tv for pc community handed a big milestone when its two orbiting satellites had been capable of talk with one another at excessive knowledge switch speeds utilizing Optical Inter-Satellite tv for pc Hyperlink (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 knowledge between satellites. Based on Amazon, it was capable of keep a secure connection between the 2 prototype satellites at a knowledge switch pace of 100 gigabits per second (Gbps) and a distance of 621 miles.
These checks validated the ultimate element of Venture Kuiper’s superior communications structure, and the outcomes make sure that OISLs might be operational on our first manufacturing satellites, slated for launch within the first half of 2024, the corporate said on its on-line information web site.
“With optical inter-satellite hyperlinks throughout our satellite tv for pc constellation, Venture Kuiper will successfully function as a mesh community in area,” Venture Kuiper’s Vice President of Expertise Rajeev Badyal mentioned in an announcement.
By making a mesh community in area, Amazon defined that it is going to be capable of enhance throughput and scale back latency throughout the Kuiper constellation and supply customers of the community extra flexibility to connect with it throughout land, sea, air, and area.
“Satellite tv for pc-to-satellite communication is the place there’s usually a bottleneck,” mentioned Peter Chahal, community and telecommunications analysis director at IDC, a worldwide market and analysis agency.
“By having this optical mesh, it’s going to permit Amazon to deal with latency points,” he informed TechNewsWorld. “By having optical inter-satellite connectivity, it’ll keep higher efficiency and decrease latency.”
Leveraging AWS
Amazon famous that one other good thing about utilizing OISLs is the pace at which knowledge may be moved world wide. Mild travels sooner in area than it does by glass, which signifies that Kuiper’s orbital laser mesh community can switch knowledge roughly 30% sooner than if it traveled the equal distance by way of terrestrial fiber optic cables, it defined.
Venture Kuiper may even profit from Amazon’s AWS service and infrastructure. “Not solely does Amazon have OISL between satellites, however it’s going to have floor stations in shut proximity to Amazon knowledge facilities so it may well keep low latency and excessive efficiency on the community from area to the terrestrial floor stations,” Chahal mentioned.
In comparison with Elon Musk’s SpaceX Starlink LEO satellite tv for pc community, which makes use of a point-to-point structure, Kuiper could be very advanced. To keep up 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 transferring at speeds of as much as 15,534 miles per hour — and all of that needs to be achieved whereas compensating for satellite tv for pc and flight dynamics.
The payoff to all that complexity, Amazon maintains, is the power to maneuver and land knowledge anyplace by way of the area mesh community, bringing safe, resilient connectivity to a variety of the corporate’s enterprise and public sector prospects.
This functionality is particularly essential for purchasers working in areas and not using a close by floor station, reminiscent of a cruise liner in the course of the ocean or an plane making a transatlantic flight, Amazon defined, whereas permitting them to securely uplink knowledge from successfully any location on Earth, transmit it by area by way of laser communications, and downlink it to their vacation spot of selection.
Good November for Kuiper
“Amazon’s optical mesh community will present a number of paths to route knowledge by area, creating resiliency and redundancy for purchasers who must securely transport data world wide,” Kuiper Authorities Options Vice President Ricky Freeman mentioned in an announcement.
“That is particularly essential for these trying to keep away from communications architectures that may be intercepted or jammed,” he continued, “and we sit up for making these capabilities obtainable to public sector prospects trying to transfer and land knowledge from distant places to their desired vacation spot.”
Amazon’s disclosure of its OISL success capped a sequence of milestones Kuiper achieved in November.
“Profitable checks have showcased the primary two-way video name, Extremely HD 4K video streaming from Amazon Prime Video, and the first-ever Amazon.com buy performed over Amazon’s Kuiper SatCom community,” Analyst Victor Xu wrote in a report for ABI Research, a worldwide expertise intelligence agency.
“These checks have validated all programs and subsystems on board Venture Kuiper’s prototype satellites,” he continued, “and have marked a considerable step ahead for the Kuiper mega-constellation, which is a deliberate constellation of three,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 progress fee (CAGR) from 2022 to 2030.
“The way forward for delivering the Web will look very totally different from what we’ve been utilizing,” mentioned expertise analyst Jeff Kagan.
“Satellite tv for pc web connectivity will play an more and more essential position in society,” he informed TechNewsWorld. “It’ll ship service to areas which have none, and it’ll supply a aggressive selection in areas the place there are restricted choices.”
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 may say that Jeff Bezos and Elon Musk share the identical dream; the distinction is that Elon Musk has already delivered what Jeff Bezos desires of,” John Strand, of Strand Consult, a consulting agency with a give attention to telecom, in Denmark, informed TechNewsWorld.
“Jeff Bezos has opened his first burger bar. Elon Musk owns McDonald’s,” he quipped.
“In the event you look additional down the street, Starlink has the benefit,” he mentioned. “They’ve entry to low cost lifting capability — the capability that’s the basis for setting these satellites up in area.”
He added that Starlink’s quantity of satellites provides it an edge not solely in area however on the bottom, too. “Once you have a look at the regulatory challenges that have an effect on this business, Starlink’s quantity will make it’s seen by the authorities in lots of international locations as an essential various supplier of significant infrastructure,” he mentioned. “This provides them higher entry to nationwide regulators.”
“It’s nice that Amazon is creating and attempting new expertise,” he continued. “Competitors is wholesome for the market, however I don’t suppose Kuiper is one thing that’s spoiling the sleep of the oldsters at Starlink.”
