DSOD-1U Mission

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.

Separation systems for satellites are required to ensure safe, controlled deployment and avoid collision or interference between the satellite and the Launch Vehicle or other objects in Space. Dhruva Space indigenously develops satellite deployment systems called Dhruva Space Satellite Orbital Deployers (DSOD).

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. 

The success of the DSOD-1U Mission paved the way for the subsequent Thybolt Mission which saw the launch of Dhruva Space’s P-DoT (Polaris Demonstrator of Technologies) Satellite Platforms. Dhruva Space conducted a sequence of technology demonstrations, which will enable advancements in research, constellation development and application agnostics.
