The aim of this project is to develop a propagation analysis tool helping the system designer to evaluate the impact of the atmosphere on a telecommunication link involving
- GEO or non-GEO satellites (LEO, MEO and HEO), including constellations
- Fixed or mobile receivers
The various propagation effects implemented in the system are: tropospheric effects (statistics for sites or regions, time series for sites), ionospheric effects for sites or regions, environment effects and interferences. Predefined systems, using models and inputs from ITU-R Recommendations, are presented to the user, as seen on Figure 1. Three systems are implemented: fixed telecommunication, mobile telecommunication and GNSS.
Figure 1: Selection of the predefined systems or the expert mode
The propagation expert can select various models and input datasets for each effect.
The output of the calculation contains graphs if applicable (Figure 2), ASCII files and Matlab files embedded in HDF5 format.
