The Technische Universitaet Muenchen has reported that transmissions of the L1/E1 signal from Galileo satellite IOV-4 (FM-4) started at about 17:15:10 GPS Time December 12. The navigation signals of both of the recently launched in-orbit validation satellites have now been activated.
A number of stations in the Cooperative Network for GNSS Observation as well as some stations participating in the International GNSS Service’s Multi-GNSS Experiment are tracking IOV-4. The satellite is using PRN code E20.
If the commissioning schedule is similar to that of IOV-3, the E5 and E6 signals of IOV-4 should be switched on over the next few days.
