Open Space Experimental Work for L-Band Mobile Satellite (MS) using a Simple and Low Cost Data Acquisition System
Mobile satellite (MS) signal performance is affected by many factors such as ionospheric effect, multipath fading and shadowing effect. Satellites transmit signals at the same strength, but things like trees and buildings can obscure a signal beyond recognition. Some experimental works have been...

| Summary: | Mobile satellite (MS) signal performance is affected by
many factors such as ionospheric effect, multipath fading and
shadowing effect. Satellites transmit signals at the same strength,
but things like trees and buildings can obscure a signal beyond
recognition. Some experimental works have been done using the
existing geo-satellite system or airborne platform in the
developed countries which is quite expensive and complicated.
Very little data is represents less developed countries such as
Africa and Asia. Therefore, a simple and low cost data
acquisition system that can be used to carry out measurement of
the MS signal performance is proposed. The experiment is
carried out in open area with no obstruction of the direct wave.
In addition, NMEA sentences will be used to obtain the required
signal propagation parameters. The measurement is then
performed to determine the relationship between the signal
performance with respect to the elevation and azimuth angles.
Results obtained from analysis will be used to determine the
characteristics of the open space environment. This method can
be used to encourage more experimental works in the less
develop countries. Propagation data for the open space
environment can be used as a reference to determine the MS
signal quality for shadowing environments. |
