Low Earth Orbit (LEO) satellites offer significant advantages in terms of extensive coverage and service connectivity. Many researchers are currently focusing on commercial LEO constellations, such as SpaceX and One Web. In particular, Signal-to-Noise Ratio (SNR) and Line-of-Sight (LoS) are crucial for ensuring high-quality service in LEO satellite communications. In this paper, we evaluate a detailed analysis of the SNR and LoS performance between SpaceX and OneWeb. The simulation results show that the LEO satellites satisfy the minimum technical performance requirements in the South Korea region.
