Tropospheric delay in microwave propagation in Nigeria [PDF]
Arabian Journal of Geosciences, 2021 Satellite communication systems suffer from the systematic error of tropospheric delay. Accurate estimation of this delay is essential for communication budget and planning. This study investigates the tropospheric delay in three Nigeria cities: Abuja, Lagos, Port-Harcourt using two different models (Saastominen and Hopfield).
