Abstract
With the evolution of radio astronomy, related education and training, the demand for scalable, efficient, and remote systems in data acquisition, storage, and analysis has significantly increased. Addressing this need, we have developed a web interface for a log-periodic dipole antenna (LPDA) array integral to the SKA Test activities at the Gauribidanur Radio Observatory (77.428 E, 13.603 N). This interface, employing Python-based technologies such as Streamlit and PyVISA, along with SCPI commands, offers a seamless and user-friendly experience. Our solution introduces a unique data acquisition approach, employing SCPI through Python to communicate with the setup's Data Acquisition System (DAS). The web interface, accessible remotely via a secure WLAN network or VPN, facilitates user-initiated observations and comprehensive logging and offers advanced features like manual RFI masking,…
