-The usual handling of BNC is that you first select a number of streams ('Add Stream'). Any stream configured to BNC shows up on the 'Streams' canvas in the middle of BNC's main window. You then go through BNC's various configuration tabs to select a combination of input, processing and output options before you start the program ('Start'). Records of BNC's activities are shown in the 'Log' tab and bandwidth consumtion per stream in the 'Throughput' tab on the bottom of the main window.

-Precise Point Positioning time series of North (red), East (green) and Up (blue) coordinate components are shown in the 'PPP' tab. Values are either referred to reference coordinates (if specified) or referred to the first estimated coordinate components. The time as given in format [hh:mm] refers to GPS Time. The sliding PPP time series window covers a period of 5 minutes. Note that it may take up to 30 seconds or more till the first PPP solutions becomes available.
