In a pioneering achievement, city-based space technology start-up GalaxEye has successfully tested its Synthetic Aperture Radar (SAR) technology on a subscale High Altitude Pseudo-Satellite (HAPS) developed by the National Aerospace Laboratories (NAL).

GalaxEye has marked a significant milestone by becoming the world’s first private entity to conduct SAR trials on a HAPS platform. These platforms, akin to high-flying drones, operate in the stratosphere, offering unparalleled capabilities for prolonged aerial surveillance.

HAPS platforms utilize solar energy and advanced battery systems to remain airborne for extended periods. At these altitudes, SAR technology becomes crucial for all-weather, round-the-clock imaging, effectively overcoming the limitations posed by cloud cover that hinder traditional electro-optical cameras.

“The rigorous test flights undertaken have provided invaluable insights, paving the way for further research and development endeavors. Our focus remains on optimizing SAR with low SWaP (Size, Weight, and Power) characteristics, unlocking unique phenomenology,” said Suyash Singh, Co-founder & CEO of GalaxEye Space.

An NAL spokesperson emphasized the importance of SAR technology for HAPS, highlighting the potential of GalaxEye’s drone-based SAR capabilities. “While the initial tests are encouraging, a series of further tests will be necessary before these platforms can be deployed for practical applications. We are positive about the possibilities,” the spokesperson said.

This collaboration between GalaxEye and NAL signals a promising future for advanced aerial surveillance and imaging technologies, with SAR at the forefront of overcoming current limitations in the field.
