Amazon’s internet satellites will communicate using lasers in space

The successful completion of the prototype testing for its satellites, KuiperSat-1 and KuiperSat-2, marks a major milestone for Amazon‘s ambitious Project Kuiper, Amazon’s internet satellites. The business is currently preparing to launch its high-end internet broadband service into orbit, revolutionizing satellite communication using state-of-the-art technology.

Space Lasers Revolutionize Satellite Communication

Project Kuiper will use lasers in orbit, as opposed to conventional satellite communication techniques, to create quick and error-free connections anywhere in the world. Data transmission between KuiperSat-1 and KuiperSat-2, which are in orbit, has been successfully demonstrated using the secret optical intersatellite link (OISL) technology.

Key Role of OISL in Project Kuiper

OISL, which offers sophisticated, dependable, and quick communication capabilities without depending on terrestrial infrastructure, is expected to play a crucial part in Project Kuiper’s communication architecture. Direct data communication between satellites will be made easier by infrared lasers, and since each Project Kuiper spacecraft has numerous optical terminals, it will be possible to connect to multiple satellites at once.

An optical mesh network will be formed in orbit by the high-speed laser cross-links that the OISL lasers will build. Over a distance of over 1,000 kilometers, Amazon claims numerous successful demonstrations aboard KuiperSat-1 and KuiperSat-2, maintaining 100 gigabits per second connectivity. This innovation verifies the last element of the communications architecture of Project Kuiper.

Overcoming Challenges in Laser Communication

There are difficulties in using lasers for satellite-to-satellite communication, such as reducing light dispersion, making contact across vast distances, and preserving a steady connection between spacecraft that are traveling quickly. These difficulties are effectively met by Project Kuiper’s cutting-edge optics and control system, which guarantees effective data transport at rates that are around 30% quicker than those of terrestrial fiber optic lines.

Bringing Connectivity to Remote Locations

Project Kuiper intends to offer a wide spectrum of commercial and public sector clients safe and robust internet access, particularly in areas without dependable ground stations. With the use of technology, data may be transmitted from far-off places, such cruise ships cruising the ocean or airplanes traveling across the Atlantic.

Advancements in OISL Technology

Broadband satellite broadband connection in low Earth orbit (LEO) has advanced significantly thanks to OISL technology. With a 30% speed increase over terrestrial fiber optic connections, the orbital laser mesh network can transfer data more quickly. Project Kuiper uses the cloud architecture of Amazon (AWS) to route data traffic efficiently.

Amazon’s Timeline and Future Plans

Project Kuiper plans to launch its first production satellites in the first half of 2024 following the completion of successful prototype tests. By 2029, 3,236 satellites are anticipated to be part of the whole constellation. Amazon intends to start conducting consumer network testing in the second half of 2024.

Project Kuiper from Amazon takes on SpaceX’s Starlink in the fight for satellite internet access. While Starlink has already launched more than 5,000 satellites and charges for its services, Project Kuiper seeks to overtake Starlink with its cutting-edge laser technology.


Project Kuiper’s successful use of space lasers represents a major advancement in satellite communication technology. With OISL technology enabling a mesh network in orbit, Amazon’s concept has the potential to revolutionize global connection by providing dependable, fast internet access to even the most distant regions of the planet.
