Optical Communication

GA-EMS' Optical Communication Terminals (OCTs) are enabling faster, higher fidelity communication transmissions. OCTs support vast networking of satellites, the sharing of data and information, and collective on-orbit computing resources in space. GA-EMS' OCTs are facilitating the evolution of modular, space-based communications services, providing a more resilient architecture to ensure 24/7 total connectivity from earth, to space, and beyond.

Adaptive Optics (AO)

GA-EMS is enhancing its optical and sensor capabilities with advanced Adaptive Optics technology for use in space-to-ground optical communication, weapons systems, weapons systems, and Intelligence Surveillance and Reconnaissance (ISR). When an optical beam is propagated at long ranges through the atmosphere, it becomes distorted by atmospheric turbulence. For free-space optical communication systems, this limits the bandwidth and operational range of the link. GA-EMS' AO system precisely measures the atmospheric distortion and dynamically corrects the turbulence effects that degrade performance. The AO system has been proven to increase the range, bandwidth, and reliability of free space optical communication systems.

Adaptive Optics Capabilities

  • Optical communication across multiple domains: Space, Air, Ground, and Maritime.
  • Imaging through turbulence for Space Domain Awareness (SDA) and ISR.
  • Optical weather for site selection (historical) and link availability analysis (forecast).
