GSA Supports Young Surveyors

22 October 2015

The European GNSS Agency (GSA) sponsored for the first time an award at the CLGE Annual Young Surveyors’ Prize.

In conjunction with INTERGEO 2015 – one of the leading international trade fairs in surveying and geo-information – the Council of Geodetic Surveyors (CLGE) awards its annual Young Surveyors’ prize for outstanding contributions to the field by students. This year, for the first time, the GSA sponsored a special topic prize dedicated to Galileo, EGNOS and Copernicus.

The winning entry came from Laura Van de Vyvere from the Liège University and M3 Systems, Belgium, for her project “Cycle Slips Detection in Quad-Frequency Mode: Galileo’s Contribution to an Efficient Approach under High Ionospheric Activity”. Through an innovative technique developed by Van de Vyvere, the project uses Galileo’s high number of carrier frequencies to improve positioning compared to other GNSS programmes.

“More than ever, precise positioning is an obvious necessity that is no longer questioned and cycle slips are a major issue in this field. We thus need to be aware of their presence and how they can make positioning unreliable,” she said. “This innovative detection method opens new doors to numerous research and commercial applications, and every Galileo user will benefit from better positioning – especially in harsh ionospheric conditions.”

The GSA and the CLGE have been working together for several years now – a cooperation that is likely to grow as the Galileo constellation moves towards completion. “With the Galileo constellation we need to understand the users, and the CLGE is an ideal platform for doing this,” said GSA Market Development Officer Reinhard Blasi. “We also need to look at what Galileo can provide in comparison to other GNSS programmes, and Laura’s project is an excellent example of how we can translate some of Galileo’s key differentiators – such as its unique frequency plan – into benefits for the end users.”
