Annex:	Order form

Radiowave propagation information for predictions for Earth-to-space path communications

This handbook provides information on radiowave propagation to assist in the design of Earth-space communication systems. It covers the following topics: propagation effects of the troposphere and ionosphere, propagation loss, sky-noise temperature, depolarization, clear air effects, transionospheric propagation, surface reflection and local environmental effects, and combined path impairments.

The handbook serves as a companion volume and guide to the Recommendations contained in the P series (Radiowave Propagation), assisting in the application of those Recommendations relevant to the fixed-satellite service, broadcasting-satellite service and all mobile-satellite services. In addition, the Handbook should represent a useful didactic reference for those seeking further knowledge of the propagation  effects on Earth-space paths.
