evan,

I added some more details about what the dynamics models mean on the wiki page:

https://wiki.paparazziuav.org/wiki/Module/GPS_UBlox_UCenter

I think the general recommendation is to use NAV5_DYN_PORTABLE for quadcopters and NAV5_DYN_AIRBORNE_2G for planes. NAV5_DYN_AIRBORNE_2G is set by default if you don't define the GPS_UBX_NAV5_DYNAMICS parameter.

Interesting ... the ARdrone is set up for the default. Looking at the datasheet, I wonder if the automotive model would actually be better for quadcopters? Max vertical velocity of 15 versus 50 m/s, and max horizontal of 84 vs 310 m/s.

Im not sure that if there is a parameter like that, just add the module it will make the configuration for you. You can just leave the parameters on default but be sure GPS outputs on right UART target which you connect the GPS to your board..

should i edit any parameters such as  "GPS_UBX_NAV5_DYNAMICS" or just add the module.

and for the GPS itself should i edit the output of the GPS protocol  such as in the picture

maybe it is related with the baud rate of your gps(I had a similar problem , ppz ucenter module can't talk with gps when it is configured to 19200 ). Configure the baud rate as 9600 on ublox , then connect gps your ppz. and don't forget to add 'gps_ubx_ucenter' module to your project..

The other problem is you could have the wrong port configured.

open the message windows and lock @ GPS to see if you ppz are receiving any gps message.
way you continue with KILL status ? kill switch with are active ?
