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.
These missions of Dhruva Space utilised the PSLV Orbital Experimental Module (POEM) which allows in-orbit scientific experiments using the spent PS4 stage as an orbital platform. A stabilised orbital platform is a significant upgrade over an orbital platform, as stabilisation helps keep the payload in an optimal position, offering several scientific advantages for the payloads that are being carried.
The PSLV-C55 mission marked Dhruva Space’s intention to fly their own or their customers' payloads on every PSLV mission of ISRO.
Head to the newsroom post for more information on the missions success.
Dhruva Space Satellite Orbital Deployers
Dhruva Space indigenously develops satellite deployment systems called Dhruva Space Satellite Orbital Deployers known as DSOD. These separation systems are compatible with ISRO’s Polar Satellite Launch Vehicle. Interfacing of the Spacecraft with the Launch Vehicle is a critical component to deployment of satellites.
All of Dhruva Space’s satellite orbital deployers have the following:
- Multiple CubeSat configurations
- Non-pyrotechnic Hold Down and Release Mechanism (HDRM)
- Pre-qualified and assembled (Mechanical, Electrical) and ready for Payload Integration
- Onboard Telemetry sensors included for deployment confirmation and Ejection Velocity measurement
DSOD-3U
Salient features
For PSLV-C55, the company’s 3U Satellite Orbital Deployer (DSOD-3U) saw successful deployment status shortly after launch.
DSOD-6U
Salient features
The 6U Satellite Orbital Deployer (DSOD-6U), designed for the storage and delayed deployment of CubeSats into Low Earth Orbit and higher orbits, rounded off a mission success with confirmation of long–duration/planned delayed deployment.
Dhruva Space Orbital Link
The Dhruva Space Orbital Link (DSOL) has been designed and was successfully tested and Space-qualified to support satellite-based data relay applications. Specifically, the configurable transceiver was made for Telemetry, Telecommand and Control, and payload data download with high data rates in S&X band with multiple modulations.
During the mission onboard PSLV-C55, successful reception was confirmed from ISRO Telemetry, Tracking and Command Network (ISTRAC) Port Blair Ground Station.
The DSOL would be integral in Dhruva Space’s future missions with their indigenously-developed larger nano (P30) and micro (P90) satellite platforms.
