Welcome to the E-GEM Project!

The E-GEM Project kicked-off in January 2014, and will last until the end of 2016. In the initial stages of the project we will be collecting inputs from existing and potential users, as well as initiating the definitions for the three E-GEM instruments. In the first few months the E-GEM project will be in touch with many potential users of GNSS-R derived products, to form a wide and varied user basis right from the start. A solid users group will be paramount to assure that the E-GEM framework is well adapted to future data needs, and to promote the usage and usefulness of the E-GEM products in the near future.

The E-GEM project will put to the test state-of-the-art GNSS Reflectometry (GNSS-R) methods for the purpose of Earth monitoring, paving the way for operational applications in oceanography (altimetry, wave height and surface winds) and biophysics (soil moisture, biomass, and ice fields).

E-GEM will be build over the world’s most comprehensive set of GNSS-R data ever collected. For achieving this task, three experimental platforms will be specially developed for the project: a satellite, an UAV and a ground instrument.

The massive data set will key for the design and validation of the processing chains and the development of high-resolution Earth observation products.

The approach of the E-GEM project is to bring together lead experts in GNSS-R technologies, experienced teams in Earth Observation domains and users. There will be no better way to address the data needs and requirements of GMES services and other Earth monitoring initiatives, plus how can GNSS-R methods best respond to the identified challenges in these domains. Institutional, public and private stakeholders will from day one have a word in the development and usage of the technology, steering the project’s efforts and increasing the awareness of this promising technology.

In technology terms, product improvement should largely result from the usage of the GPS P code (with the space- and airborne acquired signal) and Galileo’s AltBOC signals. For these purposes, the E-GEM project will rely strongly on the achievements of the GNSS-R community so far – in which European teams have historically had a leading role so far – and will bring together the individual efforts and other on-going projects into a joint working platform dedicated to the development and integration of GNSS-R technologies into GMES operational services.

Other projects and individuals interested in the E-GEM concept can request to be included in the External Users Group.
