Capella Space announced the launch of a unique satellite capable of capturing incredibly clear radar images anywhere in the world with very high resolution. The satellite's sight can penetrate even through the walls of buildings. Unlike most other satellite systems orbiting the Earth, the Capella 2 satellite can take images 24 hours at knocks and in absolutely any weather.
Payam Banazadeh, a system engineer at the NASA's Jet Propulsion Laboratory, said that with the help of the satellite, the researchers found out that half of the globe is at night, and the other half is constantly covered by clouds.
It creates problems for the devices observing the planet. The company recently launched a new platform that allows public and private clients to request and receive images from around the world. This opportunity will gradually become more accessible. It will be facilitated by the installation of six additional satellites in 2021.
The experts have already expressed their opinion that the satellites can violate privacy conditions. But the company's specialists assure that there are various conditions for fulfilling the requirements that do not allow any penetration into privacy, and the creators of the satellite adhere to them.
The main task of using new satellites is that most of the sensors involved in the work are optical imaging devices. If the clouds cover the space above the ground, it is impossible to see what is happening under the clouds.
The new satellites have vision through the cloudy shroud as well as in complete darkness. It is due to the optical image captured by synthetic aperture radar, or SAR. It works in a similar way as dolphins or bats move using echolocation.
The satellite emits a powerful radio signal at a specific frequency, and then collects data obtained by echoing this signal. And because the satellite sends out its own signal rather than passively picking up light, sometimes these signals can even penetrate right through the walls of a building, similar to the X-ray vision.
