Solar Radiation and its Effect on Signal Reception of Direct –to-Home Satellite System in some selected towns of Nasarawa State, Nigeria

Abstract

This research work examines the effects of variation in solar radiation on signal reception of Direct-toHome (DTH) satellite on Ku-Band in some selected towns in Nasarawa State, Nigeria. Data used were obtained through experimental approach of recording both solar radiation and the quality of signal received from DTH at 12.517GHz at regular interval of one hour covering two climatic conditions (Rainy and Dry seasons) in 2017. The data obtained from field was used and daily and monthly averages were evaluated. The result showed a consistence in the amount of solar radiation within the three towns (Akwanga, Keffi and Lafia) under study largely to the fact they lie within same coordinates. All the towns experience high value solar radiation in the month of March shortly before the rainy season sets in and in its lowest in August when the rainy season is at its peak. The result showed that, the state has average values of 22.7MJm2 and 15.4 MJ/m2 as high and low values respectively in the months of March and August respectively. The averaged value for the whole states showed a weak negative correlation coefficient value of -0.398 and R2 value of 0.011 when fitted into linear regression between solar radiation and the quality of signal reception within the study area.
