A17.15.2.2 Algorithm

Recommendation ITU-R P.528-5 Annex 2 describes a step-by-step method for calculating the basic transmission loss for user-specified paths. The only data needed for this method are the distance between antennas, the heights of the antennas above mean sea level, the frequency, polarization and the time percentage. The integral C++ software to generate basic transmission loss values and curves is made available in the supplement file R-REC-P.528-5-202109-I!!ZIP-E.zip, with documentation. In addition, there are select tabulated basic transmission loss values also available in the supplement file. The SEAMCAT implementation is based on the original C++ code and verified against the tabulated basic transmission loss values available in the supplement file.
