Abstract:
The satellite industry's need for Ka-band is increasing due to capacity abundance and cost efficiency. The commonly used C-band and Ku-band satellites have a limited number of geosynchronous orbital slots for given frequency bands. Thus, industries are turning to Ka-band satellites. Operating at high frequencies making them vulnerable to atmospheric conditions like rain, scintillation, dust, humidity, etc. Performance analysis of Ka-band Very Small Aperture Terminal (VSAT) system under Dust and Sand (DUSA) storms induced impairments in Dhahran city, Saudi Arabia, is presented in this paper. In this area, DUSA storms are usually observed due to desertification. Satellite communications and microwave networks are among the most commonly utilized means of communication, scattered all over the country. These networks observe radio wave degradations due to the frequently occurring DUSA storms. This study precisely quantifies attenuation due to DUSA based on real time measurements, being observed in the Eastern region of Saudi Arabia. Simulation results of real time measurements based on the level of visibility during DUSA storms are being proposed to counter the impairments in an optimized manner. These results are then analyzed in a digital video broadcasting - satellite - second generation (DVB-S2) VSAT system environment. The mentioned analysis of received signal strength during such anomalous weather conditions can aid in performance optimization by monitoring the received signal and maintaining it within acceptable level.
