Estimation of the Long-Term Propagation Losses Due To Rain On Microwave Satellite Links Over Jos, Nigeria

Abstract

This paper presents the estimation of long term propagation losses due to rain on microwave satellite links over Jos. Data were retrieved from the National Space Research and Development Agency (NASRDA) Abuja, Nigeria. The data collected was rainfall rate (mm/h) for theperiod of three year (2015–2017) over Jos. Results were obtained based on the exceedance distribution frequency of percentage time (%) and cumulative distribution of one- minute rain rate which revealed that higher rainfall rate (above 100 mm/hr) account for about 0.01 and 0.001% time ofexceedance and it is during such times that maximum propagation losses due to rainfall is significant and can be best estimated.
