DSOL, DSOD-3U, DSOD-6U Missions

In its third mission in less than a year since their first authorisation from IN-SPACe, Dhruva Space completed three in-Space experiments onboard ISRO PSLV-C55 launch. The rocket took to the skies at 02:20 pm IST on 22 April 2023, from the First Launch Pad at the Satish Dhawan Space Centre, Sriharikota.

Dhruva Space utilised ISRO's PSLV Orbital Experimental Module (POEM), which allows in-orbit scientific experiments using the spent PS4 stage as a stabilised orbital platform. A stabilised orbital platform, a significant upgrade over an orbital platform, helps keep the payload in an optimal position, offering several scientific advantages for the hosted payloads.

On 30 June 2022, Dhruva Space successfully Space-qualified its 1U Dhruva Space Satellite Orbital Deployer (DSOD-1U), aboard ISRO's PSLV-C53 Mission. The launch took place at 18:02 IST from Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh.

Dhruva Space Satellite Orbital Deployers

Dhruva Space indigenously develops satellite deployment systems called Dhruva Space Satellite Orbital Deployers (DSOD). Since interfacing the Spacecraft with the Launch Vehicle is a critical component of satellite deployment, these separation systems are compatible with ISRO’s Polar Satellite Launch Vehicle.

Dhruva Space Orbital Link

The Dhruva Space Orbital Link (DSOL) has been designed, tested, and Space-qualified to support satellite-based data relay applications. The configurable transceiver was specifically made for Telemetry, Telecommand & Control (TT&C), and payload data download, providing high data rates in the S&X band with multiple modulations.

During the mission aboard the PSLV-C55, successful reception was confirmed from ISRO Telemetry, Tracking and Command Network (ISTRAC), at the Port Blair Ground Station.

The DSOL is integral to Dhruva Space’s future missions that will use their indigenously developed larger nanosat (P-30) and microsat (P-Nu) platforms.
