Abstract :
The comparison of calculation of radio attenuation in the recommendations ITU-R P.452, and ITU-R R.1546 has been carried out. In the process of analysis the differences has been revealed: the first, calculates attenuation throughout the flight path in detail, and the second, uses approximized empirical curves. It follows that the recommended guideline ITU-R P.452 is for precise calculations, and ITU-R R.1546 is for “fast”.
