Satellite Tracking Control System for UGM Ground Station Based on TLE Calculation

by Agfianto Eko Putra, Bakhtiar Alldino Ardi Sumbada, Anas Nurbaqin

UGM ground station requires a satellite tracking control system that can follow the movements of the satellite. The system proposed in this study is relying on the calculation of Two Line Elements (TLE), the reason is that the data TLE has a subtle error. The compass sensor is used to ensure accuracy; the results were evaluated using a protractor, and about 99%. Moreover, this system is also tested to receive images from NOAA satellites using the RTL-SDR and Yagi antennas. In general, this system can follow the motion of the satellite well.

Real-time operating system implementation on OBC/OBDH for UGMSat-1 sequence

On-Board Computer or On-Board Data Handling (OBC/OBDH) has an important role as a manager for data housekeeping and communication handling between OBC/OBDH to its TTC (Telemetry and Telecommand) and EPS (Electronic Power System) subsystems in the satellite system. In order to operate according to the satellite sequence the RTOS (Real-Time Operating System) is implemented on the UGMSat-1. The CooCox CoOS is used as an RTOS which is has three tasks which are Condition-Check Housekeeping and Communication Task. The highest priority among the tasks on the system is Communication Task. The experiment proves that three tasks can run well with the time cycle of 2.034 30.047 and 1.017 seconds for Condition-Check Housekeeping and Communication task respectively. The result of overall experiments shows that the OBC/OBDH can manage data packets and sent them to Ground Station.
