| Summary: | Free space fading for satellite link propagation
studies in the equatorial regions are indeed particularly scarce,
complicated and expensive to venture upon. Most of satellite
propagation studies done in temperate climate are not
reasonable for countries in the equatorial region due to its huge
climate differences. In equatorial regions, the future
stratospheric and space-based telecommunications systems are
expected to operate with high elevation angle slant paths and
high frequency of operation from the Earth stations’ point of
view. These systems will also be sharing frequency bands with
other terrestrial and space services. From this standpoint, a
precise modelling of the vertical variation of free space path loss
parameters will be of great interest for improving the prediction
of the clear sky margin along the slant path in the tropics. In this
paper, the Free Space Path Loss (FSPL) propagation link for Xband
and S-band RazakSAT satellite will be analysed using a
Terminal Doppler Weather Radar (TDWR) data. Both links will
be evaluated and the assessment of the link’s fade margin will be
suggested. An accurate estimation of the satellite fade margin
will evidently save power from the satellite perspective and
better transmission can be estimated. The outcome of this
research will be very useful for future implementation of
satellite link fade margin improvement during non-rain
weather, both during clear sky and cloudy weather in the
tropical region. This research will facilitate the key decision
makers and the satellite designers to progress business,
availability, and throughput proficiently. Therefore, hopefully,
the spending is well reasonable with a better return on
investment (ROI) and attracts more investors in satellite
industries. |
