Re: [Paparazzi-devel] GPS 3D lock - but coordinates all zero

[Simon Liebold]

Hi Felix,

With the gps_ubx_ucenter module the GPS works again as expected. That proves that the setup was messed up (I did that). I will try to set up the same using the ucenter application. Just for the fun of it.

This page in the wiki lists the parameter DEBUG_GPS_UBX_UCENTER. But if I try to use it I get compilation errors like

modules/gps/gps_ubx_ucenter.c:107:9: warning: format '%u' expects argument of type 'unsigned int', but argument 2 has type 'uint32_t' [-Wformat]

It is not mentioned in conf/modules/gps_ubx_ucenter.xml. Deprecated?

    105 #if DEBUG_GPS_UBX_UCENTER
    106       if (gps_ubx_ucenter.baud_init > 0) {
    107         DEBUG_PRINT("Initial ublox baudrate found: %u\n", gps_ubx_ucenter.baud_init);
    108       }
    109       else {
    110         DEBUG_PRINT("WARNING: Unable to determine the ublox baudrate. Autoconfiguration is unlikely to work.\n");
    111       }
    112 #endif

Now, I just need to repair the crack in the vertical stabilizer and I'm back in the air. :-D

Hi Simon, Hi Felix,
this is the same situation (messages) as i got in september 2013.
A easy way to prove is to use a smart  phone with GPS an to look at the  co-ordinates.
I think the " UTM"  grid  (POSUTM   POSLLH) was not set in the gps module.
You can use the ublox center to prove the messages  messages view->ubx->naviation
Look to the wiki for the correct settings.

After using the config module of Version 4.03 i got the right setting.
There can be also a buck in the new subsystem GPS module.

Hi Simon,

this is strange indeed...
you could also try to let the gps_ubx_ucenter module configure the gps for you and check if you still get the same problem...

Cheers, Felix
