The Université Grenoble Alpes (UGA) is a public research university in Grenoble, France, covering all disciplinary fields. Founded in 1339, it is the third largest university in France with about 45,000 students and over 3,000 researchers. The National Center for Scientific Research (or CNRS) is a public organization under the responsibility of the French Ministry of Education and Research. Founded in 1939, the CNRS aims to evaluate and carry out all research capable of advancing knowledge and bringing social, cultural, and economic benefits for society. CNRS promotes interdisciplinary research, encouraging collaboration between specialists from different disciplines, in particular with universities, thus opening up new fields of inquiry to meet social and economic needs. This analysis center is hosted by OSUG (Observatory of Earth Sciences and Astronomy of Grenoble), a public scientific institutions dedicated to observation, research, training, and public outreach. Founded in 1985, the OSU of Grenoble (OSUG) is a School of the Grenoble Alpes University (UGA), an observatory attached to the National Institute of Universe Sciences (INSU) of CNRS (National Center for Scientific Research), and a research federation. OSUG, within the University of Grenoble, plays a major role in defining and running higher education programs and provides initial and continuing education in Earth Sciences, sciences of the Universe and environmental sciences. OSUG, within the National Institute of Universe Sciences (INSU) of CNRS, manages a number of key observing systems, which contribute to national and international databases. Through the federation of 6 research Units (including ISTerre laboratory), 5 Associated Research Teams and 2 joint service units, OSUG engages in scientific studies related to all aspects of Universe, Earth and Environmental systems.

This service in this section retrieve the GNSS Position Time Series from UGA-CNRS Analysis Center.
A time series is a chronological sequence of GNSS position measurements representing the temporal evolution of a station’s coordinates.
This function retrieves time series objects for a given station. It requires the following parameters:
station – the identifier of the GNSS station
coordinate_system – the coordinate system to be used, either ENU (East, North, Up) or XYZ (Cartesian coordinates)
The following parameters are optional :
If no date is provided, the whole time series will be returned.

Socquet, A., & Janex, G. (2019). GNSS position and velocity solutions calculated in the framework of the EPOS initiative with GAMIT-GLOBK [Dataset]. In This dataset provides GNSS solutions of permanent stations calculated in the framework of the EPOS initiative. The EPOS stations used for the processing can be found on this link : http://gnssdata-epos.oca.eu/#/site . In the framework of the EPOS initiative (p. two EPOS processing centers have been identified. ISTerre is one of them and referred to as the UGA-CNRS center. The processing parameters are those defined in 2019 and can be found on this link : https://doi.osug.fr/data/public/GNSS_products/EPOS/2019/param_GAMIT_processing_2019.txt . The EPOS solutions processed by ISTerre can be visualized and downloaded on this link : https://gnssproducts.epos.ubi.pt/). CNRS, OSUG, ISTERRE. https://doi.org/10.17178/GNSS.PRODUCTS.EPOS.2019.
