NMEA Output
This function outputs a configurable combination of the NMEA messages GPZDA,
GPGGA, GPVTG, GPRMC, GPHDT, PASHR, GPROT, GPHEV, GPGSV, PFECGPAtt, and
PFECGPHve at up to 50 Hz. The messages output and the output rate can be
configured using the NMEA output configuration dialogue in Spatial Manager.
Advanced Navigation recommends against using NMEA where possible due to the
inefciency, inaccuracy and poor error checking of the format. An example output is
shown below.

Novatel GNSS Input
This function is designed for interfacing Spatial FOG with a Novatel GNSS receiver. It
accepts data in the Novatel binary format and requires messages BESTPOSB and
BESTVELB at rates higher than 1 Hz (20Hz recommended). The message BESTSATSB is
optional to display detailed satellite information. The message HEADINGB is also
supported for ALIGN capable receivers.
