Environmental-data Collection System for Satellite-to-Ground Optical Communications

Abstract

In satellite-to-ground optical communications, it can be assumed that the link will be established if site diversity is performed among two or more ground stations connected with the terrestrial network. But by storing the data based on weather survey data quantitatively and statistically, and carrying out analysis processing needs to show the validity. Therefore, the data from ten environmental-data collection stations throughout Japan has been collected and analyzed for a statistically-long time. This paper shows the overview of this system and the analyzed site diversity effect.
