GENA for airborne gravimetry

on .

GeoNumerics' generic network adjustment software platform GENA will be used in the "GAL: Galileo for Gravity" project for the measurement of the gravity field with inertial measurement units (IMUs) and GPS/Galileo receivers on board of aircraft; a technique known as "kinematic airborne GNSS/INS gravimetry."

In the GAL project, GeoNumerics contributes an extended capability of its GENA platform in order to handle millions of unknowns. This capability is a keystone in the implementation of the dynamic network approach (Colomina and Blázquez 2004) for the solution of large systems of differential and non-differential observation equations with applications to aerial, terrestrial and marine mobile mapping.

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 (http://www.ion.org/search/browse.cfm?pub=GNSS), 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 sponsors the EuroCOW 2012 workshop

on .

GeoNumerics is proud to announce its support to the EuroCOW 2012.

EuroCOW stands for The Calibration and Orientation Workshop, the generic name of a biennial series of workshops that already started with the EuroCOW 2006.

The EuroCOWs intend to bring together the world experts, both from public and private sectors, to present and discuss the recent findings and developments in the field of geomatic sensor calibration and orientation. The EuroCOWs are highly specialized, small forums to facilitate the circulation of useful and new information between photogrammetric, remote sensing, geodetic and navigation specialists interested in the spatial orientation of sensors and in their geometric and radiometric calibration.

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.
