The messages are fully defined in sections 1 Sapphire Input Commands Detailed
Formats and 2 Sapphire Output Messages Detailed Formats.
Several different navigation solutions may be computed at a 1 Hz rate. Refer to Section
2.91, PVT1B, for detailed information. The navigation rate sets the measurement rate.
The maximum PVT output rate is 100Hz. The maximum raw data output rate is 100Hz.
These settings indicate:
On Change: The receiver outputs the specified message at the highest rate the
system can output. The rate must be purchased. For example, if the receiver has a
purchased rate of 25 Hz, the messages set at On Change are output at 25 Hz.
On Time: The receiver outputs the specified message at a rate
the purchased rate.
For example, if the receiver has a purchased rate of 25 Hz, a message may be set at
a lower output rate, such as On Time, 0.1 (10 Hz).
In the supplied utility, StarUtil 3000, the Navigation Rate setting sets the output of
the NCT Binary message PVT1B and the NMEA messages GGA, RMC and VTG,
provided that those messages are set to On Change.
The NCT Binary message MEAS1B does not follow the navigation rate. To match a higher
navigation rate, the user must schedule the output of MEAS1B. The rate must be a
purchased navigation and raw data rate.
