The IRNSS satellite network covers a large area of the India with 7 satellites, 3 geostationary and 4 that are geosynchronous. IRNSS signals are transmitted in the L5 and S-Bands. The L5 band frequencies range from 1164.45-1188.45 MHz and the S band frequencies range of 2483.5-2500 MHz. NavIC is the IRNSS satellite constellation network that can be employed to a variety of applications. The paper shows the analysis of the azimuth and elevation angle with respect to carrier to noise ratio. This study will be stepping stone for the collection of data using reflectometry. The different graphs were obtained and analyzed. Satellite tool kit is also used for the analysis of the elevation and azimuth angle.

Remote sensing is widely used for environmental monitoring including water bodies, forests and glaciers. Remote sensing technology has significant potential in the study of water bodies in terms of monitoring the distribution, change detection, and detection of contaminants. Since water resources has direct influence on various economic and developmental activities at regional and global level and further the global climatic change has prompted the regular monitoring and maintenance of water resources. Thus it is imperative to regularly monitor the spatial and temporal, changes and degradations in the water bodies. The main focus of this study is to monitor the seasonal dynamics of selected water bodies of the rural Bengaluru region with the help of Synthetic Aperture Radar (SAR) imagery of medium spatial and temporal resolution. The paper presents the processing of S-1A SAR imagery for water body mapping, extraction and determining the water surface area. The seasonal changes in water catchment area observed from the data could be correlated and validated with rainfall data and prevailing weather conditions during the period.
