rahertz waves between the ground and the satellite, the first and
key step is to find low attenuation atmospheric transparent windows. In this paper, based on the characteristics of
atmospheric distribution in China, atmospheric model (am) is used to compute and compare atmospheric absorption
attenuation of terahertz waves in two representative cities, and obtain the most ideal ground-based site suitable for
terahertz communication between the ground and the satellite in China. Subsequently, by means of real atmospheric
data and layered transmission theory, the total path loss of terahertz communication between the ground and the
satellite is calculated. Combined with the signal transmit power, antenna gain, Signal-to-Noise Ratio (SNR), noise
power and the corresponding path loss threshold, the total usable bandwidth and atmospheric windows in the 10−15
THz frequency band are given. Moreover, by taking the High Altitude Platform as the terahertz communication relay
link between the ground and the satellite, the usable a
