DSD - GPS Data no longer available

[FMFR]

Hello
I receive on DSD a trunked NXDN system, i use to have GPS on the CC channel, but few months ago, after they made a lot of changes on the network , adding several sites, also a new data frequency for each site , that doesn't seem to bring interesting data ... no more positions displayed ;

So my question is, are there new or unknow protocols for GPS that DSD fastlane isn't able to decode ? maybe the old system was NEXEDGE and they switched to IDAS ? (on the data frequency i sometimes briefly see 'IDAS' is mentionned )

I could send samples of the data if the authors are interested ;

Thanks in advance
