-PPP time series of North (red), East(green) and Up (blue) coordinate components will be plotted in the 'PPP Plot' tab when this option is ticked. Values will be either referred to an XYZ reference coordinate (if specified) or referred to the first estimated XYZ coordinate. The sliding PPP time series window will cover the period of the latest 5 minutes.

+Specify a 'Maximum Solution Gap' in seconds. Should the time span between two consecutive positioning solutions exceed this limit, the algorithm returns into the Quick-Start mode and fixes the introduced reference coordinate for the specified Quick-Start period. A value of '120' seconds could be an appropriate choice.
+</p>
+<p>This option makes only sense for a stationary operated receiver where solution convergence can be enforced because the (approximate) receiver position is known. Default is an empty option field, meaning that you don't want BNC to return into the Quick-Start mode after failures caused i.e. by longer lasting outages.

 NASA's 'World Wind' software (see <u>http://worldwindcentral.com/wiki/NASA_World_Wind_Download</u>) can be used for real-time visualization of positions provided through BNC's NMEA IP output port. You need the 'GPS Tracker' plug-in available from <u>http://worldwindcentral.com/wiki/GPS_Tracker</u> for that. The 'Word Wind' is not meant for showing centimeter level details.
