FUNDED — first satellite in development

About

Overview

FUNDED — first satellite in development

Technology

Primary: Synthetic Aperture Radar for airborne and spaceborne platforms

Products — L-band SAR satellite (in development)

Products — Miniaturised drone-mounted SAR

Products — High-resolution Ground Penetrating Radar

Differentiator: L-band. Most Indian commercial SAR efforts (PierSight, GalaxEye) are X-band. L-band penetrates vegetation and soil, giving a genuinely different capability set — foliage penetration, subsurface, soil moisture, biomass.

Form factor: Payloads optimised for size, weight and power — suitable for tactical UAVs, VTOL, fixed-wing and satellite platforms

Funding

Total raised: $7 million+

Latest round: $7M Series A, December 2025, led by 360 ONE Asset

Future plans

Next milestone: India's first private L-band SAR satellite

Timeline: 2026 target

Markets: Defence, civilian all-weather imaging
