This work here focuses on developing a web interface for the newly established Log periodic dipole antenna array at the Gauribidanur radio observatory, which enables remote observations (robust and simple), data analysis, and data sharing features.

LPDA Array This image showcases the Log Periodic Dipole Antenna (LPDA) array, the primary setup utilised by our web tool for astronomical observations and data analysis.
This web tool enables remote observations using the featured setup, allowing for data download and processing. It supports interferometry between two elements, including manual RFI marking, transit plotting, and fringe pattern analysis of the source.

Featured below are the demonstration videos of our web tool in action. The first video highlights the tool’s capability for conducting remote observations from the Raman Research Institute, located 90 km away from the Gauribidanur Radio Observatory. It also demonstrates the functionality to download collected data and perform minimal data processing. The second video showcases the updated version of the web tool, which now includes features for manual RFI masking and transit plotting, as exemplified through a solar transit observation.
