Dual-mode optical receiver for dynamic LEO Direct-To-Earth optical links: application to the CNES FrOGS OGS

In 30 seconds

The FrOGS receiver features a dual-mode front-end capable of switching between pre-amplified detection and high-sensitivity Avalanche Photodiode solutions. It incorporates adaptive optics, low-noise optical amplification, and active feedback loops to mitigate atmospheric turbulence and signal dynamics. This flexibility allows the system to maintain high-performance links during highly dynamic LEO-to-ground passes.
