How IIST and Dhruva Space propelled PSLV-C58 XPoSat mission to space

New Delhi,UPDATED: Jan 25, 2024 18:25 IST

The Indian Institute of Space Science and Technology (IIST) has played a crucial role in the successful launch of the PSLV-C58 XPoSat mission on January 1. The mission, which marked the beginning of the New Year, saw the deployment of the LEAP-TD payload developed by Hyderabad-based space startup Dhruva Space.

The LEAP-TD payload was part of the nine payloads carried by the POEM orbiting platform of PSLV C58. It was designed for technology demonstration, including telemetry and telecommand modules, among other subsystems. This marks a significant milestone for Dhruva Space, showcasing their capabilities in small satellite systems development.

IIST's involvement was pivotal, providing telemetry and telecommand support through its ground station, which is an outcome of the collective efforts of students, staff, and ISRO experts. The institute has previously contributed to four LEO missions, including InspireSat1 and various POEM payloads, demonstrating its commitment to advancing space science and technology.

The success of satellite missions heavily relies on ground communication for telemetry and telecommand. IIST's Small-spacecraft Systems and Payload Centre (SSPACE) and its ground station tracking systems have been instrumental in this regard. They have supported multiple satellites, including the recent PSLV C58 mission, ensuring continuous operations for telemetry and telecommand.

LEAP-TD, now in a ~350 km low earth orbit, is visible over IIST for approximately 10 minutes during its high elevation orbits each day. During these critical windows, the ground station must accurately track the satellite to receive telemetry and send telecommands.

A team from Dhruva Space joined forces with IIST to enhance the ground station's capabilities to meet the specific needs of the LEAP-TD payload. Their collaborative efforts paid off when they received the first beacon and telemetry signals on January 2, indicating the payload's activation.

This collaboration positions IIST as a provider of reliable ground station tracking systems and services for small satellites. It opens doors for universities and startups to leverage these facilities, fostering innovation and rapid deployment of space assets.
