Abstract
Earth observation satellites play significant role for global situation awareness. The earth observation satellites use imaging payloads in RF and IR bands, which carry huge amount of data, needs to be transfer during visibility of satellite over the ground station. Location of ground station plays very important role in communication with LEO satellites, as orbital speed of LEO satellite is much higher than earth rotation speed. It will be accessible for particular ground station for very short duration. In this project we want to develop an effective way of data transfer by situating ground stations to collect the data from maximum passes per day. Our approach is to compute and simulate sub satellite points (SSP) for ground stations to receive data for given earth observation LEO satellite with low free space loss (FSL) and accordingly situating ground stations over Indian terrain for real time data transfer. Cartosat-2B LEO earth observation satellite is taken for the case study. Cartosat-2B will complete around 14 passes over equator in a day. In those 14 passes only 4 to 5 times it will pass Indian Terrain. Our aim is to receive data at multiple ground stations and increase number of accessible passes criteria of low free space loss (FSL) has been set while selecting ground stations.
