Abstract : The Gauribidanur Decameter wave array radio telescope operates at 34.5 MHz and is located in a relatively radio-quiet zone near Bangalore. Due to the recent C-19 disruptions, the telescope was not operational for a substantial period requiring significant maintenance. The proposed poster will provide an update on the ongoing upgrade activity highlighting future observational plans, especially its importance for the low-frequency radio astronomy connections to space-based missions. We will also present details of potential sky overlap significance with the GMRT, the upcoming SKA low-frequency telescope, and its importance to pulsar observations. We will also discuss the telescope's limited polarimetric observational capabilities. Besides these details, we will also present a brief account of the RF and digital signal flow details, highlighting the digital signal processing planned using FPGA-based hardware.
