The DORIS network has been serving Earth observation satellites for over 30 years. It is more than ever at the heart of IDS challenges for the years to come. Following the IDS Retreat in 2018, several recommendations concerning the network were immediately taken on board.
We provide an update on the status of these network objectives: densification, co-location and connection with atomic frequency standards or GNSS clocks.
We review the network's overall performance in meeting the needs of satellite altimetry and geodesy: stations distribution, data availability, stations equipment, monument stability, and compliance with system requirements.
We detail the network’s main recent events and developments over the past two years: new station installations and renovations, alongside the essential day-to-day work of network teams to keep the stations in operation.
Finally, we give an overview of future prospects for continuing to improve the infrastructure in a difficult geopolitical context.
