NOKTOsat Satellite Images

Radiance calibrated nocturnal multispectral (RGB true colour) images taken from the International Space Station (ISS).
The images of the earth at night taken from the International Space Station are of the highest quality available. These high resolution photographs were taken by astronauts and are in colour, which means they offer a rare view of the earth at night in its true colours. Understandably, many people are under the impression that such photographs already exist due to the famous Black Marble image by NASA. However, the Black Marble image is a collection of black and white photographs to which a fake colour technique was applied, making it an artistic, instead of a realistic representation of the earth at night.
Although the ISS images are the highest colour resolution available, the originals have not yet been scientifically processed. Fortunately, due to a collaboration between the Complutense University of Madrid, NASA and ESA, NOKTOsat is now able to offer a scientific data reduction pipeline for the ISS images. NOKTOsat images are radiance calibrated in three channels RGB corrected by Vignetting nonlinear response of the cameras and other technical features that need correction in order to have images of scientific quality.

Environmental Impact Studies of Light Pollution and Street Lighting (EIS)

Savestar Consulting S.L. has in their portfolios the world’s leading experts in Light Pollution Studies.We carry out Environmental Impact Studies in Light Pollution using the most advanced techniques worldwide in remote sensing, modeling and prediction of the Impact of Outdoor Lighting and its impact on fauna and flora.

We are an authorized distributor of commercial licenses of “The new World Atlas of Artificial Night Sky Brightness”:

Our founders participated in the study of the growth of light pollution worldwide:

Experts in public lighting at the Spanish level:

Our researchers are part of the most important light pollution study networks in the world, such as the LoNNe network or the Spanish Network of Light Pollution Studies. They also occupy prominent positions in the organizations of defense of the nocturnal ecosystems like Celfosc, Group for the Protection of the Sky, Sky Buio, Stars4all or the International Dark Sky Association.

We collaborate with the sky quality office of the Institute of Astrophysics of Andalusia-CSIC, University of Exeter, UCM (University Complutense de Madrid), University of Santiago de Compostela, Cegep of Sherbrooke, in addition to many other researchers from other institutions.

Our policy is to have only the most demanding professionals in the Study of Light Pollution to ensure safety future legal status to our clients in the face of an increase in regulation of light pollution worldwide.We also collaborate with other companies not specialized in light pollution but of great level in their specialty as they are GeaSIG, IMAYA and Lumínica Ambinetal to offer an integral services.

Sky Darkness Certification

Savestar Consulting S.L. helps you to obtain the different certificates of the sky darkness, an added value for those tourist destinations that wish to include astronomical observation as an activity in their portfolios.It is, in addition to an attractive exercise for any population, a way to attract an audience that is increasingly interested in these issues and with an intrinsic interest in this type of activities linked to the natural environment.

As reflected in the text of UNESCO, “The Right to the Dark Skies”:

“The right to dark skies has been recognized by UNESCO as an implicit right in the conservation of cultural and natural heritage for future generations according to the Declaration in Defence of the Night Sky and the Right to Starlight (2007). It is therefore a measure that supports sustainable development. All of these subjects were analysed with the vision and knowledge of experts at The Right to Dark Skies meeting. It was also significant that the venue of the meeting was the Centre of Digital Culture in Mexico City (Centro de Cultura Digital), for there is much art in dark skies. It is such a pleasure to see the Milky Way in the night sky!”

Ranking of Light Pollution of the 8124 Spanish Municipalities

With the direct collaboration of GEASIG, we have been able to carry out the Light Pollution Ranking of the 8124 municipalities in Spain.

This ranking, among other multiple uses, can be a very good option for those companies that want to optimize their commercial resources in the detection of new business opportunities and focus their efforts on conquering those areas of Spain with the worst results.

Our studies are used to create comprehensive reports on the Environmental Impact of Light Pollution, as a complement to studies on Citizen Safety, Health and Energy Efficiency, among others that offer the best ways to proceed on the new Smart Cities Design.

In order to access the study more immediately, you can contact us or make a contribution through Patreon. Thank´s

Sky Darkness Measurement – DSDV

In order to offer a comprehensive service for the writing of reports on the environmental impact of Light Pollution, we have incorporated a vehicle with the ability to travel long distances and house the necessary equipment to obtain data and measurements in all types of environments. it’s the DSDV – Dark Sky Defender Van.

Thanks to the commitment acquired with the UCM to obtain measurements, we have the equipment that the researchers themselves use for this type of study.

Light Pollution Map with Drone Images

In the research sector, drones, as they are commonly known or RPA’s, are an increasingly evident asset that exceeds, in most cases, expectations after seeing the results obtained with the help of these small unmanned aircraft.

In our team we have accredited and highly experienced pilots with more than 200 hours of flight with drones of different weights and flight capacities.

In addition, we are in direct contact with one of the Advisors in the matter of drones / RPAs for the AESA – State Agency for Aviation Safety, which guarantees us to be up to date with the news in this sector.
