| Popis: | International audience; In 2019, new methods to synthesize time series of single-site and multi-site tropospheric impairments on Earth-space paths have been adopted by ITU-R Study Group 3 in Recommendation ITU-R P.1853-2. However, these methods are only applicable in the case of a Geostationary Earth Orbit (GEO). As the deployment of multimedia services from Low-Earth Orbit (LEO) or Medium Earth Orbit (MEO) satellites constellations is gathering momentum worldwide, the access to simple attenuation and tropospheric scintillation time series synthesizers for Non-Geostationary Earth Orbit (NGEO) applications appears to become critical. This paper presents an adaptation of the recommendation ITU-R P.1853-2 to a NGEO link in single site configuration using elevation-dependent parameters to parameterize the statistical distribution of attenuation for time series generation. |
