DBBC Setup for IVS

Open a VNC session to the DBBC you want to configure from the Applications menu on Ops4:

In C:\DBBC_CONF\ are several configuration files for different experiment types. The configurations used for IVS are:

  • dbbc_config_file_geo.txt for R1 and R4 geodesy
  • dbbc_config_file_geo_16.txt for AUSTRAL sessions
  • dbbc_config_file_APSG_CRF.txt for APSG, CRDS and CRF geodesy
  • dbbc_config_file_T2_OHIG.txt for T2 and OHIG
  • dbbc_config_file_rdv86.txt for RDV86

The default configuration is kept in dbbc_config_file.txt and this will be loaded when the server software is started. (If you want to change the default, Copy (i.e. Do NOT rename) the appropriate file to dbbc_config_file.txt)

Check to see if a program called DBBC Control net.exe is running. If not, start it and say “y” when asked if you want to use the default config, otherwise “n”.

Start DBBC Control net.exe which can be found on the Desktop. If you didn't accept the default config, load the file you want now with the LOAD command. e.g.:

load=dbbc_config_file.geo.txt

Then configure the DBBC with a

reconfig

Configurations will take about 2 minutes.

When the configuration is complete, synchronise the DBBC to the station pps with the following command:

Enter Command: pps_sync

You now need to set up the IF system. The commands to do this depend on the IVS observation and the station.

For R1, R4, CRF, CRDS, AUSTRAL and RDV experiments on they should be:

dbbcifa=1,agc,1
dbbcifb=4,agc,4
dbbcifc=2,agc,2
dbbcifd=2,agc,2
dbbcform=geo

For APSG, OHIG and T2 experiments, for all stations they should be:

dbbcifa=1,agc,1
dbbcifb=4,agc,1
dbbcifc=2,agc,2
dbbcifd=2,agc,2
dbbcform=geo

Recommended DBBC power levels can be found here. Current target values for the total power readings is 56000. this can be checked by the command: ifa, ifb, ifc or ifd. If the levels are too high or low, then adjust the attenuation on the IF box. Note that the levels on IF C (e-remote control command: ifc) are a bit low. Don't worry about it.
