Space‑based Layer Hardware Strategy

Construction Strategy

Do not recommend self‑built satellite hardware, including constellation, control center and ground receiving station.

Recommend purchasing commercial satellite data services.

Recommended Services

Optical remote‑sensing satellite data service (30cm to 1m resolution).

SAR synthetic aperture radar satellite data service.

Hyperspectral satellite data service under project‑based procurement.

SDaaS Advantages

Cut construction cost by over 90%.

Faster data refresh and shorter delivery cycle.

Access multiple satellite constellations simultaneously.

Convenient for future function expansion.
