Hourly satellite coverage to uncover your world.

For decades, large, expensive satellites operating under government flags have given us petabytes of stunning, rich images. As beautiful as these images are, limited coverage areas and unreliable revisit rates make it impossible to create viable benchmarks for assessing a dynamic and unstable planet.

Capella’s constellation of small but powerful satellites employ space-based radar, beaming through darkness and cloud cover to gather the information you need to make informed decisions. When fully deployed, Capella will offer hourly coverage of every point on Earth, rendered in sub-meter resolution, through the world’s largest constellation of radar satellites.

Small on Earth, big in space

Capella satellites weigh less than 40 kg and can be built, launched and maintained for a fraction of the cost of large satellites, and far faster. When fully deployed, our Capella small sat constellation will be comprised of 12 polar orbits, a geometry optimized for maximum global coverage and revisit times that never exceed one hour, and are typically less.

Data acquisition in all weather, day or night

Space-based imagery has long captivated the public, but optical satellites are limited by two factors: light and weather. Cloud cover and darkness mean that at any given moment, only about 25% of the Earth’s surface can be captured through optical imaging. Capella’s SAR satellites, operating in the X-band, can see through clouds and in the dark, so you always get the information you need when you need it. 100% of the time.

Optical Imagery Limits:

50% Night

50% Cloudy

25% Visible

SAR: No limits
