Description
The authors present a web-based front end satellite tracking application for the automated tracking of two student-designed CubeSat satellites scheduled for launch in 2024 operating with a full duplex scheme in the UHF and commercial S-band frequency bands. Satellite signals are captured and processed by integrating GNU Radio with the Ettus Research USRP x300 SDR hardware. The USRP x300 provides the necessary bandwidth and sensitivity to track the satellites' signals and extract telemetry data. The application uses GNU Radio's signal processing capabilities to implement the DVB-S2 communication standard and the QPSK modulation scheme, ensuring compatibility and efficient communication with the tracked satellites. Challenges such as Doppler shift compensation, signal demodulation, and synchronization are addressed, enabling reliable and accurate satellite tracking. Integrating GNU Radio with external open-source software and libraries, such as GPredict, enhances its satellite tracking capabilities. This integration facilitates precise satellite position prediction, automated tracking, and communication scheduling. The satellite tracking application utilizing GNU Radio and the USRP x300 SDR showcases the potential of open-source tools in revolutionizing satellite tracking and analysis. The work presented aims to improve satellite communication, space exploration, and scientific research in the upcoming era of satellite deployment.
