Aims and Objectives
The following steps were taking in achieving the objectives of the study:
- Compute some propagation impairments relevant to fixed satellite communication at Ku, Ka and V band (10-50 GHz) at elevation angles of 50, 550 and one practical elevation angle for links to recently launched Nigeria communication satellite NigComsat-1 in the 37 locations in Nigeria.
- Use meteorological data from satellites and ground stations as input data into ITU-RP empirical models to generate appropriate propagation data such as, cloud attenuation, rain attenuation, gaseous attenuation, tropospheric scintillation and total propagation loss on earth-space path in each of the 37 locations.
- Calculate mappings following item 2, for uplink and down link budget control during tropical rainfall along earth-space paths for fixed satellites communication service in Nigeria.
- Finally, locate the highest and the lowest places affected by propagation impairments year round by dividing the country into six zones (namely SW, SE, SS, MB, NW and NE) and conduct a comparative analysis of the results with a view to recommending for the country in the future where to best site a fixed satellite base station on earth-space path (operating at Ku band and above) for deep space exploration.
