Table 22: Supported NMEA input messages
12.4.7
NMEA Output
This function outputs a configurable combination of NMEA messages at up to 50 Hz.
The messages output and the output rate can be configured using the NMEA output
configuration dialogue in Spatial Manager. A complete list of available messages can
be found in section 13.10.15.
Advanced Navigation recommends against using NMEA where possible due to the
inefficiency, inaccuracy and poor error checking of the format.
An example output is shown below.

Novatel GNSS Input
This function is designed for interfacing Spatial 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 HEADING is also
supported for ALIGN capable receivers.
