[IGSSTATION-9162] PolaRx5 firmware update supporting GPS PRNs G35 and G36

[Peter.Steigenberger at dlr.de]

Dear PolaRx5 station operators,

according to the recent NANU 2026027, spare GPS satellites will transmit PRNs G35 and G36 with unhealthy navigation message:

In order to enable the tracking of these PRNs by the IGS network, I would like to ask all PolaRx5 station operators to update to the most recent firmware version 5.7.0 that supports these PRNs (as well as G38 and G39) and to enable these satellites in the RINEX generation. Please note that neither G35 nor G36 have been tracked so far.

Thanks for your support
