- Abstract
- For 6G standardization and communication network, each country invests in Low-Earth-orbiter (LEO) communication satellite business. However, there are the threats of signal interference by frequency-band and collision among the satellites in space due to the recent launch of numerous LEO communication satellites such as Starlink , Oneweb, and Kuiper. In particular, the issue of frequency registration for satellite operation and the interference of receiver and transmitter between ground and satellite are studied a lot.In this study, we calculate an optimized numbers of communication satellites by an analysis for the continuous operation constellation covering Korea and perform some simulations by calculating the numbers of satellites required for the beam coverage according to altitude and orbit inclination. We analyse satellite total numbers, orbit plane, and optimizing parameter for the continuous coverage of communication. The optimization parameter in designing the constellation of communication satellite is dominant by the Earth -centered half cone angle in star pattern and relative phase parameter between satellites in adjacent orbit planes , F, by delta pattern. In the 45-degree inclined orbit at the 888km altitude, using a delta pattern (F=1), at least more than 2 satellites out of 80 satellites are continuously visible over Korea.
