The ATENEA project at the ION GNSS 2011

on .

The first results and status of the ATENEA project were presented at the international annual conference ION GNSS 2011 which took place from September 19th to 23rd, 2011, at the Oregon Convention Center, Portland, Oregon, USA. The presentation was held by Antonio Fernández (DEIMOS Space) and the corresponding paper, available in the conference proceedings (, is co-authored by members of the ATENEA consortium partners: DEIMOS Space (ES), DEIMOS Engenharia (PT), the Institute of Geomatics (ES), the Politecnico di Torino (IT), GeoNumerics (ES) and TopScan (DE). Mariano Wis was the GeoNumerics co-author.

GeoNumerics begins work for the Galileo FP7 research project ATENEA

on .

On February 2nd 2010, in Brussels (Belgium), the kick-off meeting (KoM) of ATENEA took place. ATENEA stands for "Advanced Techniques for Navigation Receivers and Applications". It is an FP7 project realised by an international consortium led by DEIMOS Space (Tres Cantos, ES) whose goal is to design, build and test an advanced hybrid Galileo receiver that will integrate inertial and LiDAR measurements to perform robust, accurate and precise navigation under the paradigm of INS/GNSS/LiDAR close, tight and deep integration.

GENA for radiometric block adjustment

on .

The Spanish company ALTAIS will use the generic network adjustment software platform GENA for the radiometric calibration and modelling of high resolution airborne digital imaging.

Radiometry is the measurement of radiance. It is a fundamental technique of astronomy, Earth remote sensing and modern photogrammetry. A digital imaging sensor measures incoming radiance (L) and stores the result of the measurement as a digital number (DN). Two central phases in the imaging process are the radiance transfer from object to a system and the transfer of the radiance entering the system (at-sensor radiance) to DNs inside the system. The units of L are W·sr^(-1)·m^(-2) (Watt per steradian per square metre). DN is dimensionless.
