ISRO’s PSLV-C56 to Launch with Six Co-passenger Satellites on 30th July

The Indian Space Research Organization (ISRO) is all set to embark on a momentous mission with the Polar Satellite Launch Vehicle (PSLV-C56). The launch, scheduled for 30th July at 6:30 AM, will carry Singapore’s DS-SAR satellite alongside six co-passenger satellites. The event will take place from the renowned Satish Dhawan Space Centre in Sriharikota.

DS-SAR Satellite

Singapore’s DS-SAR satellite, weighing 3600 kg, is the result of a collaboration between DSTA, representing the Singaporean government, and ST Engineering. It is destined for a Near Equatorial Orbit (NEO) at an altitude of 535 km and a 5-degree inclination.

A Synthetic Aperture Radar (SAR) payload, developed by Israel Aerospace Industries (IAI), equips the DS-SAR satellite. This cutting-edge feature enables all-weather day and night coverage with exceptional imaging capabilities at a 1m-resolution and full polarimetry.

Upon deployment and operational status, the DS-SAR satellite will play a pivotal role in fulfilling the satellite imagery requirements of various Singaporean government agencies. Additionally, ST Engineering will utilize the satellite to provide multi-responsive imagery and geospatial services for its commercial customers.

Co-Passenger Satellites

Joining the DS-SAR satellite are six co-passenger satellites:

  1. VELOX-AM: A technology demonstration microsatellite.
  2. Atmospheric Coupling and Dynamics Explorer (ARCADE): An experimental satellite.
  3. SCOOB-II: A 3U nanosatellite housing a technology demonstrator payload.
  4. NuLIoN by NuSpace: An advanced 3U nanosatellite facilitating seamless IoT connectivity in urban and remote regions.
  5. Galassia-2: A 3U nanosatellite designated for a low earth orbit.
  6. ORB-12 STRIDER: A satellite borne from international collaboration.


The impending launch of PSLV-C56 carrying the DS-SAR satellite and six co-passenger satellites signifies another moment of pride for ISRO’s space exploration endeavors. With the advanced SAR payload, the DS-SAR satellite is poised to deliver invaluable support to both the Singaporean government and commercial entities. Moreover, the inclusion of diverse co-passenger satellites highlights ISRO’s commitment to advancing space technology through international collaboration, catering to a wide array of applications.


Q1: When is ISRO launching the PSLV-C56 mission?

Ans: On July 30 at 6:30 AM, the PSLV-C56 mission is slated to lift off from Satish Dhawan Space Centre’s first launch pad in Sriharikota.

Q2: What are the capabilities of the DS-SAR satellite?

Ans: Synthetic Aperture Radar (SAR) is a payload that Israel Aerospace Industries (IAI) developed for the DS-SAR satellite. As a result, the satellite can offer full polarimetry and imaging at 1 m resolution for all weather day and night coverage.

Q3: What is the significance of the DS-SAR satellite?

Ans: The DS-SAR satellite will support the satellite imagery needs of several agencies within the Singaporean government once it is operational. It will also be used by ST Engineering to provide multi-responsive imaging and geospatial services to their business clients.
