The American company Capella Space showed images from its Capella-2 satellite that was launched in August last year. It turned out that it can take ultra-precise photos even at night, through clouds and walls. The company will now sell these images to government departments and individuals on a specially dedicated platform.
In the pictures, one pixel is equal to a square measuring 50 by 50 centimeters – this is ten times sharper than its counterparts. Capella Space has achieved this using synthetic aperture radar rather than a conventional camera.
It sends a 9.65 GHz radio signal to the object and then interprets the data. Echolocation works similarly in dolphins or bats. This technology is not proprietary to Capella Space, but they are the first to use it commercially.
Since the satellite sends its own signal, and does not pick up light, it can even peer through the walls of buildings, regardless of the time of day and weather. Capella Space says the skyscrapers are the easiest to look through.
Capella Space believes government agencies can use its satellite to conduct hostage rescue operations or monitor airports. Scientists could watch the Amazon rainforests, and investors could watch the global supply chain. At the same time, the company stressed that customers' plans should not violate US law.
