Design and Construction of Satellite Tracking Rotator and Ground Station for Low Earth Orbit Satellites

Abstract

The report entitled “DESIGN AND CONSTRUCTION OF SATELLITE TRACKING ROTATOR AND GROUND STATION FOR LOW EARTH ORBIT SATELLITES” presents the design and construction of a ground station and rotator utilizing a helical antenna that is compatible with the SatNOGS database. The ground station comprises a support structure, a helical antenna, a rotator and a radio receiver. The selection of a helical antenna is justified by its directional pattern and high gain, making it optimal for satellite tracking. A rotator is integrated to monitor the satellite's movement across the sky while the radio receiver decodes the signals. The SatNOGS database provides a comprehensive catalogue of satellite orbits and schedules that can be used to plan observations. Building a ground station with a helical antenna and rotator allows for satellite tracking and communication, contributing to the network of satellite tracking stations worldwide. This report delves into the details of the ground station's design and construction, including the necessary components, support structure and software required for optimal operation. Additionally, the use of the SatNOGS database for scheduling observations and monitoring their progress is explained. The report concludes with a discussion of the potential applications of the ground station, including future scope and satellite operations.
