GeoNumerics enters the GAL consortium

on .

GeoNumerics is proud to announce that, as of 2013-01-07, it has joined the GAL project consortium.

In the GAL project, GeoNumerics will contribute an extended capability of its GENA platform in order to handle millions of unknowns and the further development of the dynamicSURVEY model toolbox for GENA. The extended capability of GENA is a keystone in the implementation of the dynamic network approach for the solution of large systems of differential and non-differential observation equations with applications to aerial, terrestrial and marine mobile mapping. The model toolbox dynamicSURVEY will implement the mathematical models to derive gravity perturbations from inertial observations (linear accelerations and angular rates) and GPS/Galileo carrier phase observations.

The GENA design principles presented at the ISPRS XXII Congress

For the first time, a number of features and design principles of the GENA platform and model toolboxes have been publicly presented in a joint paper co-authored by Dr. Ismael Colomina, Dr. Marta Blázquez, Dr. José A. Navarro (Institue of Geomatics, IG) and Mr. Jaume Sastre (GeoNumerics, GN). The paper discusses the relevance of extensible network adjustment programmes in view of the current wave of sensor technology and the needs for rapid sensor prototyping (in the sensor design phase), rapid sensor orientation and calibration modelling (in the sensor commercialization phase) and accurate sensor orientation and calibration (in the sensor exploitation phase).

In the paper, the need for software tools that allow for rapid and safe development of models -with protection of intellectual property rights if desired- is translated into software specifications of simplicity, genericity and extensibility that, in turn, lead to architectural constructs where the general robust non-limear least-squares (RNLLS) functionality is concentrated in a software platform and the specific sensor features (models) are concentrated on reusable software components.

Big welcome for Dr. Marta Blázquez as she joins our team

We’re delighted to welcome mathematician and geomatician Dr. Marta Blázquez as GeoNumerics' new Scientific Programme  Manager.

Dr. Blázquez graduated in Applied Mathematics at the Technical University of Catalonia (UPC, Barcelona, Spain). Later on, she obtained a MSc in Airborne Photogrammetry and Remote Sensing from the Institute of Geomatics (IG, Castelldefels, Spain) and a PhD in Aerospace Science and Technology (UPC).

“It is a pleasure to welcome Dr. Blázquez aboard, an acknowledged expert for kinematic geodesy and photogrammetry, who is well versed in all aspects of sensor orientation and calibration. Her expertise in applied mathematics, scientific software development and technical project management makes her the perfect person for fostering our research and development activities in the field of trajectory determination for mapping and remote sensing applications,” said Jaume Sastre, GeoNumerics' Chief Operations' Officer.

PhD defence by Marta Blázquez: GENA for and from advanced research

on .

On July 3rd, 2012, at the Auditorium of the Institute of Geomatics (IG), Marta Blázquez defended her PhD thesis entitled "A systematic approach to airborne sensor orientation and calibration: method and models." The PhD research was supervised by IG's director Dr. Ismael Colomina.

The goal of the thesis is to establish a methodical basis of a systematic approach to airborne sensor orientation and calibration and to prove its validity with newly-developed models and applications. The thesis, organized as a collection of four peer reviewed papers and two proceeding papers, introduces the concepts of relative aerial control, of spatio-temporal orientation and calibration, of "Fast AT" and of dynamic networks. The contributions of Dr. Blázquez thesis are manifold and fundamental to the field of modern sensor orientation and calibration. The thesis research focused on frame cameras but its potential application scope is much broader, including line cameras, laser scanners and virtually any type of remote sensing data acquisition instrument. GENA stands for "Generic Extensible Network Approach" and is GN's software platform for parameter estimation under the paradigm of network modelling and estimation. GENA was a key tool for Dr. Blázquez research and, at the same time, has benefited from her research.
