Abstract: Geomatics engineering is an emerging and fast growing interdisciplinary field which has found increasing applications in telecommunications industries. This paper presents the techniques of determining the geodetic variables, the azimuth and elevation angles, which are used as GIS inputs in radio signal propagation along earth-satellite path. A case study of Geomatics application in propagation studies over Ku band in tropical Malaysia is presented. The measurement site was at Universiti Teknologi Malaysia, UTM, Malaysia (Lat.: 1.45°N and Long.:103.750E). The geodetic variables are used for determining the optimal position of the earth station receiving antenna. The computed values of the elevation and azimuth are 75.59° and 262.79°, respectively. These values are considered to be accurate because they are very close to the values specified in the antenna aiming chart provided by ASTRO for the site under study. It has been demonstrated in this paper how the elevation of the receiving earth station can affect the quality and strength of the received signal. The study will provide useful information for the radio engineer in optimizing both the signal quality and strength in the earth-satellite propagation.
