NMEA logging findings - just interesting info


Rob Giuliano
 

I am running APRSIS32 2020-10-27 1838 (Development Version) and noticed something different about NMEA logging.

I am running the same uBlox M8 modules I use at work with a different configuration. 
On all units the port I am using sends only NMEA strings (no ubx or RTCM#).
When I use a work GPS with APRSIS32, I get errors in the log, but only when logging is disabled?

Digging a little deeper, I find the configuration differences between errors and no errors are:
Key settings with Errors
Numbering used bfor SVs not supported by NMEA:    Strict(no output)
                                                              Main Talker ID:    System dependent
                                                               GSV Talker ID:    GNSS Specific (or Use main Talker ID)

FIX: To fix it, I change the Main Talker ID to GPS(GPS) and GVS Talker ID 'must be' Use main Talker ID to stop reporting errors.

After that, I can change Numbering ... NMEA or  Main Talker ID without errors, until GVS Talker ID gets changed to GNSS Specific, then the erros return and both settings (Main & GSV) must be as specified above to reset it.

Interesting, the GPS information appears to update properly the entire time. 

I am happy to report that APRSIS32 does not restrict decode to $GPxxx strings, but seems to accept $GLxxx, $GNxxx, and $GBxxx.  It goesn't seem to like the Galileo ($GAxxx) strings for the same message types (RMC, GGA, GLL, etc.). 

Thanks for supporting multiple formats as most modern GPS units now seem to send the combined ($GNxxx) messages by default.

This error is when APRSIS32 attempts to match up the satellites in view by PRN # to put the Configure / Screen / Satellites numbers inside the circle based on azimuth and elevation.  I'll double-check that the sentences would probably pick that up.  If you could turn on logging for a short bit when you're getting the errors, it might help.  The errors SHOULD be there regardless of the Enable setting.

I'll also take a look at what talkers are supported and add $GA if you can confirm that the remainder of the sentence format matches the other talkers.

I'll be honest, the only thing I thought odd was that the logging continued while disabled.
My comments on message related to what many (if not most) newer GPS units send by default.  I am not so sure the $GA message are that important.  They were not being sent by default.  I had to change settings to get them to show.  Same with $GB (BeiDou).  I was just curious and noticed the $GB messages were decoded.

This error is when APRSIS32 attempts to match up the satellites in view by PRN # to put the Configure / Screen / Satellites numbers inside the circle based on azimuth and elevation.  I'll double-check that the sentences would probably pick that up.  If you could turn on logging for a short bit when you're getting the errors, it might help.  The errors SHOULD be there regardless of the Enable setting.

I'll also take a look at what talkers are supported and add $GA if you can confirm that the remainder of the sentence format matches the other talkers.
