Global Navigation Satellite Systems Engineering, Policy, and Design
GMV Aerospace and Defense has developed a system for a pan-European, public time distribution. At the recent AltPNT Demonstration Day at the European Commission’s Joint Research Center (JRC), Ricardo Píriz, from GMV AD’s GNSS Time and Frequency Group, explained how his company can provide Galileo System Time (GST) or Galileo UTC via existing networks.

The SAGAIE network was deployed in West-Africa in 2013 to assess the feasibility of an equatorial for ASECNA SBAS by studying ionospheric scintillation. This study of the network’s measurements, taken between 2013 and 2016, analyzes the characteristics of the scintillation recorded by five receivers that cover Sub-Saharan West-Africa.
