GEO feeder links with Onera’s Optical Ground Station FEELINGS: analysis of 2 years of results and operation and perspectives brought by point ahead turbulence mitigation

In 30 seconds

The FEELINGS optical ground station provides a 600 mm aperture adaptive optics demonstrator to evaluate GEO feeder link performance over two years. The research focuses on mitigating atmospheric channel influences and turbulence-induced power fluctuations to enable high-data-rate communication. By analyzing the intersection of optical propagation and adaptive optics corrections, the project identifies key requirements for deploying reliable laser communication links near urban environments.
