Astrolight is a Lithuanian deep-tech company operating at the forefront of the space and defense technology sectors. Founded in 2019 and headquartered in Vilnius, the company specializes in the design, development, and manufacturing of advanced free-space optical communication systems. Its core mission is to solve the critical data bottleneck that exists between space-based assets and Earth. As the number of satellites in orbit grows exponentially, generating vast amounts of data, traditional radio frequency (RF) communication methods are becoming increasingly congested, slow, and insecure.
Astrolight's vision is to create the "optical backbone network for space." The company aims to replace or augment legacy RF systems with next-generation laser communication (lasercom) technology. By using lasers to transmit data, Astrolight can offer significantly higher bandwidth, faster data rates, and inherently more secure communication links that are resistant to jamming and interception. This positions the company as a key enabler for the future of Earth observation, satellite connectivity, deep space exploration, and secure multi-domain defense operations. Astrolight is a dual-use technology company, actively developing solutions for both the commercial space industry and defense applications, including participation in NATO's prestigious DIANA accelerator program.
What the Company Actually Does
At its heart, Astrolight is an end-to-end provider of laser communication solutions. The company's primary activity is the engineering and production of the physical hardware required to establish high-speed optical links across vast distances. This involves two main components: the space terminal that is integrated into a satellite, and the ground station that receives the data on Earth.
Astrolight's approach is defined by full vertical integration. The company designs and manufactures its entire technology stack in-house, from the optical assemblies and electronic subsystems to the complex pointing, acquisition, and tracking (PAT) software. This control over the entire system ensures optimal performance and reliability. A key function of the company is solving the immense challenge of maintaining a stable laser link between a satellite moving at thousands of miles per hour and a precise point on the ground. This requires sub-microradian pointing accuracy and sophisticated systems to mitigate atmospheric interference.
Beyond just selling hardware, the company's long-term strategy is to offer Optical Communication as a Service. This involves not only supplying the terminals but also operating its own network of optical ground stations to provide a complete, seamless data downlink service for satellite operators. A significant part of their work also involves adapting their space-developed technology for terrestrial defense applications, such as secure ship-to-ship communications.
Products and Services
Astrolight's products are highly specialized hardware systems designed for extreme environments and mission-critical performance. Their offerings are divided into space-based terminals and ground-based stations.
1. ATLAS Series Laser Communication Terminals (LCTs)
The ATLAS series represents Astrolight's product line of space-based terminals designed for integration into satellites, particularly those in Low Earth Orbit (LEO). These terminals are engineered with a focus on low Size, Weight, and Power (SWaP), making them ideal for smaller satellites where every gram and watt is critical.
ATLAS-1: A demonstrator and first-generation LCT designed to provide a high-speed data downlink. It serves as a foundational product to prove the core technology and achieve space heritage.
ATLAS-2: The second-generation terminal, compatible with Space Development Agency (SDA) standards. It is optimized for high-volume data transmission (up to 2.5 Gbps) for Earth observation missions and is designed to work seamlessly with Astrolight's own ground stations. The terminal is capable of self-calibration in orbit to increase link reliability.
Key features of the ATLAS terminals include data rates that are more than 10 times faster than comparable RF systems, low power consumption, and a modular design that can be adapted for various satellite buses.
2. Optical Ground Stations (OGS)
To complete the communication link, Astrolight develops the corresponding ground infrastructure.
OGS-1 Portable Optical Ground Station: This is one of Astrolight's most innovative products. The OGS-1 is a complete, high-performance ground terminal that is uniquely designed to be portable. The entire system?including the telescope, optical head, tracking computer, and modem?can be disassembled and packed into standard luggage for transport. This allows for the rapid deployment of a data downlink station in remote locations, disaster areas, or temporary operational theaters, providing ad-hoc, high-bandwidth connectivity where it's needed most. The system's effectiveness has been successfully demonstrated in collaboration with the European Space Agency (ESA).
OGS-2.5 Optical Ground Station: This is a more permanent ground station designed to be a key node in Astrolight's planned network, providing robust, high-capacity data reception for commercial and governmental satellite constellations.
3. Defense and Multi-Domain Communication Systems
Leveraging its dual-use technology, Astrolight is developing systems for terrestrial defense applications. A primary focus is on secure ship-to-ship laser communication for naval forces. By using undetectable laser beams instead of broadcast radio waves, ships can communicate with high bandwidth while drastically reducing their electromagnetic signature, enhancing operational stealth and resilience against enemy jamming and surveillance.
