The European Patent Office (EPO) has granted the IAC a patent on an invention developed within IACTEC-Space. This technology improves the quality of images obtained by high-performance cameras under the demanding conditions found in space.

The effectiveness of this technology has already been tested on three space missions, applying it to the DRAGO (Demonstrator for Remote Analysis of Ground Observations) cameras, developed at the IAC for Earth observation from space. Carlos Colodro, electronics engineer at IACTEC-Space and the main person responsible for this development, comments that "thanks to this technology, we have been able to obtain details in the images that would otherwise have gone unnoticed, while also improving the precision of specific measurements obtained remotely, such as the humidity level of the observed vegetation."

Images taken by the DRAGO-2 camera onboard the ALISIO-1 satellite, based on uncooled InGaAs technology. With the proposed method, images can be properly corrected regardless the acquisition configuration and operating temperature, revealing features that would otherwise be hidden by sensor noise.

Although this technology was developed with the intention of using it in space missions, it can be directly and easily applied in other fields where improving the quality of the images obtained is important, especially in situations where ambient temperature variations can affect camera performance. This type of situations is common in the industrial, automotive, and environmental monitoring sectors, among others.

In addition to achieving improved image quality, cameras incorporating this technology can benefit from significant reductions in weight, volume, and power consumption. These characteristics are precisely what give DRAGO its ability to observe in the shortwave infrared (SWIR) from small satellite platforms.

With the granting of this patent, the IAC reaffirms its commitment to innovation and public-private collaboration, of which IACTEC is a prime example and which is primarily channeled through the IAC's Knowledge Transfer Office (OTC). Thus, the invention covered by this patent is available for licensing and transfer to companies that wish to exploit it.

The Instituto de Astrofísica de Canarias (IAC) has started its development of DRAGO-3 , the third generation of its instrument: Demonstrator for Remote Analysis of Ground Observations (DRAGO), designed for Earth observation from space in the short wave infrared region of the spectrum (SWIR). This new instrument comes after the success of DRAGO-1 and DRAGO-2 , which have proved their utility in key applications such as following volcanic eruptions, hydrological monitoring of regions affected by climate change, and the control of forest fires.
