Using Ubuntu Linux 64b 11.10, i had used BNC in the past; When using it yesterday i had set some configuration settings apparently wrong. The UI froze. had to power off the computer. today the UI will not come up, ive rebooted 2 times and tried downloading other linux versions.

All of them launch then have no UI, but doing ps -ef |grep B* shows each of them running. looking at the logfile i then saw the same error as yesterday, apparently its spinning trying to do something but i cannot change the config file. There may be some change made such that if the program is stalled it brings up a dialog box asking the user what to do?

Actually RTCM standard does not allow to transmit accelerations for orbit corrections with messages 1057, 1060, 1063, 1066, but anyway if BNC includes this code, they should be accounted for properly.

const double H2 = 0.6090;
const double L2 = 0.0852;

Since IERS Conventions 1996 it is recommended to use the following values:

h20 = 0.6078 l20 = 0.0847
