About
FUNDED — first satellite in development
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
