CACI Delivers High-Bandwidth Free-Space Optical Modem for NASA International Space Station Communications

Company Release - 2/10/2022

Advanced laser communications technology will be integrated at MIT Lincoln Laboratory in support of multi-domain space missions

RESTON, Va.--(BUSINESS WIRE)-- CACI International Inc (NYSE: CACI) announced today that it has delivered a free-space optical modem as part of the Integrated Laser Communications Relay Demonstration (LCRD) Low-Earth Orbit (LEO) User Modem and Amplifier (ILLUMA) program to MIT Lincoln Laboratory, which will integrate CACI’s advanced laser communications mission technology with other equipment for delivery to NASA.

The ILLUMA program provides high-bandwidth optical communication from the International Space Station (ISS) to the Earth and back via the LCRD mission satellite, which will deploy in geosynchronous orbit. ILLUMA will be launched in 2023 and installed on the ISS, where it will serve as a low-Earth terminal for NASA’s multi-year LCRD mission to demonstrate high-speed, laser-based communications.

CACI is the leading U.S.-based FSO laser communications provider for space, airborne, and terrestrial missions to U.S. government and commercial customers. Our innovative technology enables faster, more direct communication in low-earth orbit, improving performance for missions ranging from national security to human spaceflight.

CACI’s advanced laser communications technology for the ILLUMA program will transform the way data, video, and other information is sent and received using lasers to encode and transmit data at rates 10 to 100 times faster than today’s radio frequencies, at significantly less mass and power. And with the recent acquisition of SA Photonics, the combined portfolios bring a rare synergy of innovation and scaled manufacturing capabilities.

Linda Braun, Vice President of Photonics Solutions at CACI, said, “Space-based missions are producing larger volumes of data and demanding higher data rates, increasing the need for new communications technology. CACI’s decades of experience supporting the full lifecycle of space ground, launch and operations combined with innovative resilient communications technology enables these transformative solutions for NASA’s missions.”
