Which optical ground stations are used for Optel-® in-orbit demonstration?This scenario is using network-6, that consists of Zurich and Tenerife as optical ground stations, illustrated in Fig. 14. The LEO satellite to be used for the OPTEL-μ® in-orbit demonstration will be in a Sun synchronous orbit at an altitude of around 670km.
What is the difference between RF stations and optical stations?The RF stations have a fixed bitrate whilst the optical ones are adapting to the current link conditions. The long contact duration of the Esrange and Inuvik sites is due to their high latitudes and polar orbits.
What are optical high bitrate communication links?Optical high bitrate communication links are maturing and will likely be a part of the future strategy for transferring ever growing amounts of data from satellites to the ground, including for the small satellite segment.
