Program realization of calculation method of radio signal attenuation in atmospheric gases for satellite communications



The authors study the application of calculation method of radio signal attenuation in atmospheric gases, proposed by International Telecommunica­tion Union [1]. The paper describes the algorithm of attenuation calculation, created in MATLAB program and calculated resulting attenuation for latitu­des are greater than 45°.
