    80 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. The bandwidth consumtion per stream, the latency of incoming observations and PPP time series for coordinate components are shown in the 'Throughput', 'Latency' and 'PPP' tabs of the main window.

    953953PPP results are shown in the 'Log' tab on the bottom of BNC's main window. Depending on the processing options, the following values are shown about once per second (example):

    959 The 'PPP' string in that is followed by the selected mounpoint, a PPP time stamp in GPS Time, the number of processed satellites, and XYZ coordinates with their formal errors as derived from the implemented filter in [m]. If the troposphere estimation flag is set then the estimated troposphere correction follows together with its formal error in [m]. The implemented algorithm includes an outlier and cycle slip detection. The maximum for accepted residuals is hard coded to 10 meters for code observations and 10 centimeters for phase observations.

    962 More detailed PPP results are saved in BNC's logfile. There you find the estimated

    1018 <p>
    1019 You may specify X,Y,Z reference coordinate components for the receiver's position if known. The North/East/Up time series plots shown in the 'PPP' tab will then be referred to these values. The default values for the coordinate components are empty option fields, meaning that BNC will refer time series plots to the first estimated position and not to any reference coordinate.
     1024<p><a name="pppnmearef"><h4>3.11.3 Plot Origin - optional</h4></p>
     1025<p>
     1026Select an origin for North/East/Up time series plots in the 'PPP Plot' tab. Note that this makes only sense for a stationary receiver. Available options are
     1027<ul>
     1028<li>'Start position', meaning that BNC will refer time series plots to the first estimated position.
     1029</li>
     1030<li>'X Y Z', meaning the known reference coordinate components for the receiver's position.
     1031</li>
     1032</ul>
     1033Default is the selection of an empty option field meaning that no PPP time series will be plotted in the "PPP Plot' tab..

    1112 Precise Point Positioning time series of North (red), East (green) and Up (blue) coordinate components are shown in the 'PPP' tab when the 'Static' PPP option is applied. Values are either referred to reference coordinates (if specified) or referred to the first estimated set of 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.

     1126Precise Point Positioning time series of North (red), East (green) and Up (blue) coordinate components are shown in the 'PPP Plot' tab when a 'Plot origin' option is defined. Values are either referred to reference coordinates (if specified) or referred to the first estimated set of 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.
