Real time

Sept. 9, 2021

Since the first half of 2021, 26 RESIF-RENAG stations have been broadcasting their data in real time (see map here) via a Ntrip server hosted at the Observatoire de la Côte d'Azur. Most of these stations are equipped with a Trimble NetR9 receiver and a multi-GNSS geodetic antenna that receives signals from GPS, GLONASS and Galileo satellites. To access the data stream, the connection is free and subject to identification:

Ntrip server: gnssfr.unice.fr:2101

login/password: on request by mail to RENAG data center (renagdc_at_oca.eu) or via the Contact page

The list of network stations broadcasting in RTK is available here: http://gnssfr.unice.fr:2101/

Several open-source softwares allow to process data broadcasted by Ntrip streams, from format conversion to RTK or PPP positioning:


Real-time products (correction and ephemeris) are available free of charge from the IGS (registration here) and can be used to perform PPP positioning in real-time.

The RTK broadcast of RENAG stations will soon be integrated into the public open-source collaborative network Centipede.
