Free-space point-to-point optical links can be implemented using infrared laser light, although low-data-rate communication over short distances is possible using LEDs. Infrared Data Association (IrDA) technology is a very simple form of free-space optical communications.
The laser beams from the spacecraft will be received by the 200 inch (5 m) Hale Telescope at Palomar Observatory in California. [4] Laser beams to the spacecraft will be sent from a smaller telescope at the Table Mountain Observatory in California. First light was achieved on 14 November 2023. [5]
It routinely downloads high-volume data from the Sentinel 1A/B and Sentinel 2A/B spacecraft to ground. So far (April 2019) more than 20000 links (11 PBit) have been performed. [23] As of May 2023, EDRS has over one million minutes of communications [24] with more than 50,000 successful inter-satellite links. [25] [26]
The goal of the OPALS mission was to demonstrate a downlink of a short video from space using laser communication. In doing so, the following was studied: Maintenance of an optical link between the ground and space with various environmental and operational conditions [7] Processing of distorted data [7]
