What is Gfg2?
• The EU acknowledged the need to better assess the scientific value of GNSS beyond their classical positioning services
• Gfg2 - GNSS for Global Environmental Earth Observation (GEEO) and GEOSS
• Gfg2 is a three year coordination action funded by the 7th Framework Program of the European Commission under the Environment theme (2010)
• Mission: to better asses the value of GNSS for Global Environmental Earth Observation (GEEO) and GEOSS

Gfg2 Goals
To consolidate a community of experts interested in the scientific exploitation of GNSS for GEEO and GEOSS
To explore novel applications derived from GNSS for GEEO and GEOSS while enhancing research-industry collaboration to implement these applications
To identify the research and technological challenges and define the strategic vision, roadmap and policy for GNSS for GEEO and GEOSS available or under development
To assess the value of a European GNSS independent constellation (EGNOS-GALILEO) in the support to GEEO and GEOSS
To promote the public understanding of GNSS for GEEO and GEOSS research and use within the GEO
Use of GNSS signals• Most current applications receive and process
GNSS (GPS) signals directly– timing and position
• GNSS – Radio Occultation (GNSS-RO), based on delays of the signals when traveling through the atmosphere– e.g. temperature, humidity
• GNSS – Reflectometry (GNSS-R), based on the reflection of the signals from different surfaces– e.g. soil moisture, surface roughness, …
GNSS use in positioning• Use in field tools for bird/mammal counting
and tracking (GPS)• Digital elevation modelling (wetlands)• Designing and coordinating European
biodiversity field monitoring
GNSS Radio Occultation (GNSS-RO) measurements of phase path delay
key atmospheric/climate parameters
e.g., refractivity N,
geopotential height Z,
temperature T, humidity q

Ongoing Activities
• Determining existing and future GNSS-GEEO activities and needs on positioning, for mass-market or scientific work;
• Explore novel applications of GNSS for GEEO and GEOSS with specific attention to the needs of Earth and Ocean observation systems;
• Consolidate a GNSS community of experts for GEEO;• Organisation of Summer schools, worshops and
industry events (TEDx Barcelona 2013);• Develop a road map for further R&D.
• Essential Climate Variables (ECVs)– What can be measured using GNSS?
