Description	High Altitude Platforms (HAP) can bring a possibility of a very fast additional coverage e.g. in the case of catastrophes, when existing networks collapse, or could be utilised as alternatives to satellite or terrestrial systems. In this paper electromagnetic wave propagation aspects for HAP systems are discussed. In the first part, atmospheric gas attenuation for inter-HAP links is determined. Next part of the paper deals with the influence of rain on millimetre wavelength links between user stations and High Altitude Platform. Typical route diversity scheme given by the recommendation ITU-R P. 618 used for satellite links cannot be accurately applied. Based on simulation results HAPs are analyzed and particular corrections for the Czech Republic are proposed.
