Data from China's leading commercial missions:
Jilin-1Beijing seriesSuperViewTianyi SARGalaxy SpaceHaisi SARZhuhai-1Fengyun
Four data layers, one order.
We source from multiple Chinese commercial operators, so you compare resolution, revisit and price in one place instead of negotiating with each one.
Optical
Sub-metre to 5 m imagery with frequent revisit over most of the globe. Good for mapping, construction tracking and site checks.
Archive and new tasking. GeoTIFF, COG.
SAR radar
Sees through cloud and at night. Used for flood extent, ship detection and millimetre-scale ground movement with InSAR.
SLC, GRD, change maps.
Hyperspectral
Dozens of narrow bands to separate crop types, mineral signatures and water quality.
Calibrated reflectance cubes.
Weather
Global gridded forecasts, nowcasting and typhoon tracks, combined with satellite cloud imagery and historical climate records.
REST API, GRIB2, NetCDF.
Answers, not just pixels.
Most customers don't want raw scenes. We combine imagery with weather to deliver the measurement their work depends on.

Remote sensing indicators plus weather
What each layer shows.
The same place looks different to each sensor. Combining them gives an answer that no single image can.
Illustrative imagery.
The satellites behind the data.
We work with China's commercial operators and public weather missions. Each order names the satellite and operator, so you always know where your data comes from.
Optical
High-resolution imaging
- Jilin-1Chang Guang Satellite Technology. Large constellation with frequent revisit, plus video satellites.
- Beijing seriesTwenty First Century Aerospace Technology. Wide-area mapping imagery.
- SuperView (Gaojing)China Siwei Surveying and Mapping Technology. Very high resolution scenes.
Best for mapping, construction and site checks.
SAR radar
All-weather, day and night
- Spacety (Tianyi)Commercial small SAR satellites.
- Galaxy SpaceCommercial SAR and satellite platforms.
- Haisi seriesCommercial SAR focused on ocean and coastal monitoring.
Best for floods, ships and ground movement.
Hyperspectral and multispectral
Material and crop identification
- Zhuhai-1Orbita Aerospace. Hyperspectral and video constellation.
Best for crop types, minerals and water quality.
Weather
Observation and forecasting
- Fengyun seriesChina's public meteorological satellites.
- Commercial weather smallsatsGNSS radio occultation and microwave sounding.
- AI forecast modelsBuilt in-house and with research partners.
Best for forecasts, nowcasts and climate risk.

Four ways to buy.
Start small with a single archive scene, or hand us an entire region to watch all year.
Archive
Existing scenes, priced per square kilometre and delivered within hours.
Tasking
New captures scheduled for your area and dates, on optical or radar satellites.
Monitoring
An annual subscription with repeat coverage and change alerts for your sites.
Analytics
Finished results such as yield, flood extent or subsidence, with no imagery skills needed.
How a new capture works.
Need an image that doesn't exist yet? We schedule a satellite to take it.
Draw your area
Upload a boundary or draw it on the map. Set the date window and resolution.
Get a feasibility check
We confirm which satellites can reach it, when, and the price, usually within one working day.
Satellite captures
Optical or radar passes are scheduled. You see each attempt and the cloud cover.
Ready-to-use delivery
Processed files arrive by API, cloud bucket or download, with the analysis if you ordered it.

Frequently asked questions.
Short answers to what buyers ask first. For anything else, email our sales team.
Can I buy imagery outside China?
Yes. That is our core business. Every order is cleared for export under Chinese regulations, and we deliver worldwide by API, cloud bucket or download.
How is Chinese commercial imagery different from Maxar or Planet?
It combines high revisit and competitive pricing, with strong coverage of Asia, the Middle East, Africa and Latin America. Many customers use it alongside their existing suppliers.
What is the difference between archive and tasking?
Archive is imagery already captured, so it is cheaper and faster. Tasking schedules a satellite to capture your area on the dates you need.
Do I need remote sensing experts to use the data?
No. Our analytics deliver finished results such as crop condition, flood maps or ground movement, ready for your reports and systems.
Which file formats and standards do you support?
Imagery comes as GeoTIFF or Cloud Optimized GeoTIFF, with a STAC catalog. Weather data comes as GRIB2, NetCDF or JSON over REST.
