Re: [Paparazzi-devel] Lisa/M terminated standby circling [SOLVED]

[Balázs GÁTI]

Hi,

I've implemented the GPS Ublox Ucenter module in the airframe file 
(http://wiki.paparazziuav.org/wiki/Module/GPS_UBlox_UCenter), thus the 
GCS displayed ground speed and the circling problem disappeard.

I am very pleased for the quick respond! You turned our day to a 
success.

Regards,
 Balazs
