| Summary: | Signal degradation in Mobile Satellite (MS) is due to
several factors such as ionospheric effect, multipath fading, treeshadowed
and building-shadowed. This affects the Mobile
Satellite Service (MSS) to provide continuous communication
service to the users. Since there is not adequate data available on
the signal performance of the MS in the Asian continent, thus, an
experimental work is essential to be carried out to investigate the
effect of factors such as the tree-shadowed and buildingshadowed
on the signal strength. This paper discusses the cost
effective set up. It can be used to measure the effect of trees and
buildings on the received mobile satellite signal operating in the
L-band. The methodology uses to carry up the experimental
works is discussed in detail. The measurements of the signal
performance are performed under different MS environments
such as tree-shadowed and building-shadowed and hence the
results are compared to the data obtained for open space
environment. The analysis of the signal performance under
different MS environments is performed with respect to the
elevation and azimuth degree at different time under a clear sky
condition. The analysis produced forms an important part in the
studies of the signal performance. From this research work, we
would like to propose a simple and low cost data acquisition
system in order to encourage more experimental works to be
carried out especially in the less developed countries. |
