-BNC allows to output results from Point Positioning in NMEA format. The NMEA messages generated are
-<ul>
-<li> one leading GPRMC message which carries only date and time information, plus</li>
-<li> about once per second a GPGGA message which mainly carries the estimated latitude, longitude, and height values.</li>

+BNC allows to output results from Precise Point Positioning in NMEA format. The NMEA sentences generated about once per second are pairs of 
+<ul>
+<li> GPGGA sentences which mainly carry the estimated latitude, longitude, and height values, plus</li>
+<li> GPRMC sentences which carry only date and time information.</li>
+</ul>
+</p>
+<p>
+Note that Tomoji Takasu has written a Windows program called RTKPlot for visualizing NMEA strings. It is available from <u>http://gpspp.sakura.ne.jp/rtklib/rtklib.htm</u> and compatible with the NMEA output of BNC's PPP option.
