GEO-K supports ESA for Sentinel-2 data calibration using drones

Our UAV equipped with MAIA multispectral sensor and ILS (Incident Light Sensor) flew on 26-11-2020 at 10:03 UTC over selected test site, overlapping exactly the passage of Sentinel-2 satellite. The UAV altitude was of 90 m with a GSD of about 5 cm and a FOV of 60 m × 45 m.

The flight has been carried out in the contex of QA4EO ESA project which aims to tackle the challenges associated to surface reflectance and BRDF validation using advanced UAV-based techniques.

New flights and data elaboration are scheduled in the next months.

Visibility trials for drone detection

GEO-K, collaborating with the RADARLab of the Electronic Department of the “Tor Vergata” University, is performing drone’s visibility trials making use of its exa-rotor high-quality carbon fiber frame drone, an X-band radar and a corner reflector with known RCS. These tests are going to show the detection capability of Radar Systems, retrieving also the radiometric characterization of commercial drones.

The term “drone” is commonly used to indicate an unmanned aerial vehicle (UAV), or an aircraft which is remotely controlled by a ground-based operator. During the last years, drones have increasingly captured the interest of entrepreneurs and investors alike as a means to take over certain tasks, such as commercial, scientific, recreational and agricultural applications, surveillance services, product deliveries and aerial photography. Recently, the growing use of drones also among common people is due to the possibility of purchasing them at a lower price, increasing concerns about their use. Last year, in fact, more than 3456 incidents involving drones were recorded, compared with only 1237 in 2015, PA news agency reported. Moreover, drones have been reported to be used for criminal purposes and illegal actions. The problem of how drones can be detected and controlled over a limited area is directly rising up. Radar sensors are suitable to detect big objects, but drones may also be seen.

 

GEO-K StormTrek at 2015 EUMETSAT Meteorological Satellite Conference

The number of the extreme meteorological events has increased in the last few years and the trend should be the same for the next future”.

GEO-K participated in the 2015 EUMETSAT Meteorological Satellite Conference, held in Toulouse, France, 21-25 September, presenting StormTrek, the innovative algorithm for the nowcasting of extreme meteorological events.

These events generally develop very quickly and on a small scale, nevertheless they may provoke several damages and affect also the human’s safety. For these reasons it is very important to monitor and prevent these natural hazards by means of advanced techniques which must be able to:
● detect the event as soon as possible
● track the behavior of the event
● predict the short term development of the event

StormTrek is a novel multispectral algorithm for the detection, the tracking and the short term forecast of convective objects developed by GEO-K.
The model is already operational and some web services based on its output are already available. Our work is aimed to show the results of the validation activity developed in the last year. StormTrek validation involves the comparison with benchmarks like the Rapid Development Thunderstorms, developed by Meteo France, and the lightning activity over Europe and South Africa

University of Rome Tor Vergata is the only Italian University in the QS Top 50 Under 50

Over the years, the University of Tor Vergata has continually improved its position in the international rankings: in the recently published QS World University Top 50 Under 50 2014 ranking (less than 50 years old universities), Tor Vergata risen yet again advancing by 5 positions, more precisely from 38th to 33rd in the world. This result is even more significant considering that it is the only Italian university present in this ranking.

The position is established after considering 6 indicators: the academic reputation, the number of quotes, the level of preparation of the students, the quality of the teaching and international activities, and the employment opportunities.

According to the QS research, 20% of the best young universities in the world are in Australia that accounts for the highest number of universities among all 25 countries present in the ranking, followed by Spain with 5. Hong Kong and the United Kingdom have 4, whilst Germany has 3. Korea, Canada, Sweden and the United States of America all have 2.

GEO-K won the Best Ideas challenge at the GMES Masters Competition 2012

GEO-K and SERCO prized at the Global Monitoring for Environment and Security (GMES) Masters competition (GMES MASTERS 2012). GEO-K and SERCO won the “Ideas Challenge” competition proposing  “MOSP-RIOS – OFF-SHORE OIL SPILL & FLARING MONITORING”, a service for the monitoring of gas flaring and of oil spilling from off-shore platforms using GMES products.

The competition, in its second year, received more than 100 innovative business proposals from 20 European countries. The 2012 winners were announced at the event, in Munich, organized by Anwendungszentrum Oberpfaffenhofen (AZO) GmbH, on 25 October 2012.
