There is more data in the NMEA sentences but each has a different mix (GGA, GLL, RMC etc.) but #satellites used, 2d/3d, time of fix etc. are handy to display. Unfortunately the SV6 module from BGMicro only ouputs GGA and VTG. TSIP (and probably the binary protocols from other manufacturers) is much richer. You can get signal levels, elev/AZM of satellites, time parameters such as GPS/UTC offset and so on. Also, the binary protocol is the path to configuring the receiver operating parameters.

I don't think that a terminal emulator is the right tool for monitoring the binary protool on a PC. Trimble makes available tools for their receivers and also provides source code as an example for users writing their own interfaces. Look at the Trimble FTP site fot "TK...exe"
