Current obstacles

SAR data processingTerabytes daily requires massive ground processing and automated feature extraction.
Manufacturing scalingRamping from 50 to 100/year while maintaining cost and quality requires automation.

Physics limits

Resolution-swath trade-offFiner resolution requires larger antennas or longer observation; designs balance 16-cm resolution with 400-km swath.
Revisit frequencySingle satellite revisits same location every ~100 minutes; real-time monitoring requires many satellites.
Power and thermal limitsSAR is power-intensive; microsatellites constrained by battery and thermal limits on radar dwell and transmission bandwidth.

How it works

3 parts

Synthetic aperture radar

Radar imagery from orbital motion

SAR reconstructs high-resolution images by combining radar echoes as satellite orbits.

Miniaturization

Lightweight SAR under 100 kg

ICEYE innovation compresses SAR into microsatellites, enabling constellation density.

All-weather

Microwave penetrates clouds

Radar operates at wavelengths penetrating clouds, rain and darkness for persistent monitoring.
