Astrolight scales ATLAS laser terminals to challenge proprietary satellite network lock-in

The shift toward open-standard optical links provides a critical path for satellite operators to bypass the spectrum bottlenecks and electronic warfare vulnerabilities of traditional radio-frequency systems. By adhering to SDA and ESA specifications, Astrolight enables defense and commercial entities to build independent transport networks that are not tethered to a single provider's infrastructure. This interoperability is essential for the streaming industry's long-term data backhaul needs as orbital density increases. Watch for the results of the 2027 PHOENIX 2 flight demonstration to validate real-time 2.5 Gbps throughput during high-velocity re-entry phases.

The Space Development Agency has become the primary driver of open-standard optical communications in low Earth orbit. By requiring all laser terminal suppliers to comply with a common set of interoperability specifications, SDA has helped propel the industry forward, executives said at the SmallSat Symposium. The agency's Proliferated Warfighter Space Architecture calls for each satellite to carry three to five laser links capable of 2.5 Gbps crosslinks, with vendors already demonstrating 10 Gbps and some claiming 100 Gbps capability. Astrolight's ATLAS terminals target that same 2.5 Gbps threshold and align with SDA and ESA specifications, placing the Lithuanian company in direct competition with an established supplier base that includes Mynaric, Tesat-Spacecom, Skyloom, and CACI.

The competitive dynamics of that supplier base have shifted significantly in recent months. Mynaric delivered more than 130 laser terminals to York Space Systems and Northrop Grumman supporting SDA's Tranche 1 Transport Layer, marking a turnaround after a year of supply chain troubles and restructuring. The 42 terminals shipped to York Space rode to orbit aboard 21 York-built satellites for the first plane of the constellation. Meanwhile, CACI's optical terminal passed initial ground interoperability tests required for SDA satellite contracts, establishing a data link with a reference modem built by the Naval Research Laboratory. SDA technical director Frank Turner stated the agency invested in the NRL optical interoperability testbed specifically to ensure multi-vendor compatibility before launch, emphasizing that the agency does not want a single company to own the market.

Astrolight's broader strategy extends beyond intersatellite links to encompass a full-stack optical network. The company raised a €2.8 million seed round in May and plans to deploy its first optical ground station in Greenland, with intersatellite link payload demonstrations expected in 2027. CEO Laurynas Mačiulis told Payload that the company is developing optical ground stations, laser terminals for intersatellite links, and optical terminals for Navy vessels simultaneously, arguing that terminal hardware alone holds no value without supporting ground infrastructure. That full-network approach differentiates Astrolight from terminal-only suppliers and addresses a bottleneck that SDA itself has acknowledged: commercial constellations use single-manufacturer satellites, whereas require proven cross-vendor optical handoffs that have yet to be demonstrated in orbit at speed.
