A placement method of ground stations for optical satellite communications considering cloud attenuation
نویسندگان
چکیده
This letter studies a placement method of optical ground stations (OGSs) to realize site diversity in satellite-to-ground communications under cloud attenuation. Using meteorological ERA-Interim database, the monthly average attenuation over Japan during 2018–2022 is calculated. Based on obtained results, set candidates for OGS proposed, including places with lowest attenuation, major cities, and JAXA observatory station. Then, greedy heuristic presented determine sub-optimal OGSs. Simulation results reveal that sufficiently high system availabilities are achieved when performed from proposed candidates.

Ground stations networks for Free-Space Optical communications: maximizing the data transfer
Free-space optical communications are becoming a mature technology, but unlike current radio-frequency technologies, they are strongly impacted by clouds. In this paper, we aim to find a network of optical ground stations maximizing the amount of data that can be sent from a low-earth orbiting satellite to the Earth during its missions, taking into consideration cloud information. We present a ...

A bidirectional horizontal-path optical link was demonstrated between Strawberry Peak (SP), Lake Arrowhead, California, and the JPL Table Mountain Facility (TMF), Wrightwood, California, during June and November of 1998. The 0.6-m telescope at TMF was used to broadcast a 4-beam 780-nm beacon to SP. The JPL-patented Optical Communications Demonstrator (OCD) at SP received the beacon, performed f...
متن کاملRain Attenuation Impact on Performance of Satellite Ground Stations for Low Earth Orbiting (LEO) Satellites in Europe
Low Earth Orbits (LEO) satellites are used for public communication and for scientific purposes. These satellites provide opportunities for investigations for which alternative techniques are either difficult or impossible to apply. Ground stations have to be established in order to communicate with such satellites. Usually these satellites communicate with ground stations at S-band. The commun...
