GalaxEye deploys GLX-SQ payload aboard ISRO’s PSLV Orbital Experimental Module

In News

• Indian start-up GalaxEye successfully deployed its GLX-SQ payload aboard ISRO’s PSLV Orbital Experimental Module (POEM-4) launched on December 30, 2024.
• This marks the world’s first-ever fusion of Synthetic Aperture Radar (SAR) and optical imagery in orbit.

About the GLX-SQ Payload

• Developed by Bengaluru-based space start-up GalaxEye.
• Innovation: Combines SAR (all-weather, day-night imaging) with optical imagery (high-resolution visual data).
• Processing Capability: Converts analog signals into digital format in <10 minutes for real-time insights.
• Applications: Defence surveillance, precision agriculture, disaster management & climate monitoring.

Significance

1. Technological Milestone
   • First payload globally to achieve SAR–optical integration in orbit.
   • Enhances Earth observation beyond traditional remote sensing.
2. Strategic Value
   • Boosts India’s capabilities in defence reconnaissance and disaster resilience.
   • Reduces dependence on foreign Earth observation technologies.
3. Future Roadmap
   • GalaxEye is preparing Mission Drishti, a flagship multi-sensor satellite for all-weather, high-resolution imaging.

About POEM (PSLV Orbital Experimental Module)

• Repurposes the PSLV’s fourth stage (PS4) as an orbital platform for experiments.
• Provides power, telemetry, and command support for payloads.
• Facilitates low-cost testing of new technologies for start-ups, academia, and NGEs.
