120 Envizio Pro and Envizio Pro II Installation and Operation Manual
The PRN scroll list allows the operator to manually set the PRN, or pseudo-random number, for the differential
satellite which provides coverage for the operation area if desired. Selecting a PRN from the list locks the
correction signal to the selected satellite. If the ‘auto’ option is selected, the field computer will scan and
automatically set the PRN throughout an operation.
Note:
If the vehicle position jumps on screen during field operations in ‘auto’ mode, try selecting a PRN
manually. The jumps may be a result of the internal receiver switching between differential
satellites.
Toggle the “Gl1de Enabled” option to enable the NovAtel Gl1de

When enabled, the NovAtel Gl1de

Note:
The NovAtel Gl1de
®
feature is only available on Envizio Pro II field computers with the dual
frequency GPS receiver. Visit the NovAtel website for a full description and additional information
on the NovAtel Gl1de
®
feature.
