The Indian Space Research Organisation (ISRO) continues to make strides in space exploration and international collaborations. The upcoming launch of the Polar Satellite Launch Vehicle-C56 (PSLV-C56) carrying Singapore’s DS-SAR satellite marks another significant milestone in the space agency’s journey. Scheduled for July 30, this launch will enable Singapore to enhance its satellite imagery capabilities and support various government agencies.
PSLV-C56: Setting the Stage for Singapore’s DS-SAR Satellite
The PSLV-C56 is set to take off from the Satish Dhawan Space Centre in Sriharikota. Similar to its predecessor, the C55, the PSLV-C56 will be configured in its core-alone mode. This configuration involves a standalone launch without any accompanying strap-on boosters. By opting for this approach, ISRO can efficiently deploy multiple satellites on a single mission, offering a cost-effective and reliable solution for various international partners.
DS-SAR Satellite: A Joint Effort between Singapore’s DSTA and ST Engineering
The DS-SAR satellite is the centerpiece of this mission, developed through a collaborative effort between the Defence Science and Technology Agency (DSTA), representing the Government of Singapore, and ST Engineering. Its primary objective is to support the satellite imagery requirements of various government agencies within Singapore.
Advancements in Imaging and Geospatial Services
ST Engineering, a leading technology provider, aims to leverage the DS-SAR satellite for multi-modal and highly responsive imagery and geospatial services. These services cater to their commercial customers and are expected to provide valuable insights for sectors such as agriculture, urban planning, disaster management, and environmental monitoring.
Unveiling the Capabilities of DS-SAR
The DS-SAR satellite is equipped with a cutting-edge Synthetic Aperture Radar (SAR) payload developed by Israel Aerospace Industries (IAI). This SAR payload brings several advantages, including all-weather day and night imaging capabilities. Regardless of adverse weather conditions, the DS-SAR can continue capturing high-resolution images at 1m resolution with full polarimetry. This groundbreaking feature significantly enhances its usability and reliability for various applications.
PSLV-C56’s Co-Passengers: Expanding the Satellite Fleet
Accompanying the DS-SAR satellite on its journey are six co-passengers, each with its unique purpose and mission objectives. These satellites contribute to a diverse range of research and technology demonstration activities. The co-passengers include:
- VELOX-AM: A 23 kg technology demonstration microsatellite designed to validate and test various onboard systems.
- ARCADE: An experimental satellite aimed at studying atmospheric coupling and dynamics, providing crucial data for weather forecasting and climate research.
- SCOOB-II: A 3U Nano satellite carrying a technology demonstrator payload. Its mission is to test and validate new technologies in the space environment.
- NuLIoN: An advanced 3U Nano satellite developed to facilitate seamless IoT (Internet of Things) connectivity, catering to both urban and remote locations.
- Galassia-2: A 3U Nano satellite intended to operate in low Earth orbit, conducting research on space-based systems and technologies.
- ORB-12 STRIDER: An international collaborative effort resulting in a satellite developed to perform a specific mission.
