GNSS and Earth Observation
Expanding the role of GNSS
During the past 40 years, GNSS has become an important part of many human activities. In addition to the traditional role of providing global position, navigation and timing information (PNT), the navigation signals are now being used in new and novel ways.
Whole new areas of scientific study are opening up; to examine the way in which the signals can provide information about the nature of the atmosphere, and even about the surfaces from which they have been reflected, before they are captured by a receiver.
Earth Observation (EO) scientists monitor global environmental systems using in-situ and remote monitoring tools. Their findings provide support tools for decision makers across a range of interest areas; from safety and security, to the natural environment.
GNSS signals are seen as an important new source of information: because they are a free, real-time, and globally available resource for the EO community.
If you wish to find out more about the diversity of potential applications of GNSS for EO, and the work of various European organisations and projects working in the area, visit the links below:
The Benefits of GNSS for Earth Observation a short booklet describing the potential of GNSS in the work of two major European initiatives: Copernicus and the GEO.
Copernicus formerly known as GMES (Global Monitoring for Environment and Security), is the European Earth Observation system. It was set up to provide reliable and up-to-date information on environmental and security matters.
NEREUS encourages the use of space technologies to benefit the European Regions.
GEO (Group on Earth Observations)
EBONE (European Biodiversity Observation Network) An initiative to understand the potential uses of GNSS for biodiversity studies.
GEOBON-GEO (Biodiversity Observation Network) An initiative to understand the potential uses of GNSS for scientific activities.
Gfg2 (GNSS for Global Environmental Earth Observation (GEEO) and Global Earth Observation System of Systems (GEOSS)). A European funded project to assess the value of GNSS for Earth Observation.
