"DGPS Backup" (automatic backup with
VBS signal)
To overcome the long convergence time or sometimes
degraded signal associated with OmniSTAR® HP/XP/G2
correction, precision farming systems offer OmniSTAR®
VBS correction as backup to OmniSTAR® HP/XP/G2
enabled receivers.
• While OmniSTAR® HP/XP/G2 is converging, the sys-
tem uses OmniSTAR® VBS correction to enable field
operation with DGPS in the meantime.
• If the OmniSTAR® HP/XP/G2 signal degrades, the sys-
tem uses OmniSTAR® VBS correction as a backup.
Press the "DGPS Backup" window to access the pop-up
options window.
Press "VBS" to enable backup.
Press "None" to turn backup OFF.
When you use the "Precision Farming" application with-
out the "Autoguidance" application, the transition between
OmniSTAR® VBS and OmniSTAR® HP/XP/G2 is seam-
less with no notification when the change occurs. The
"GPS Status" window reports which technology is cur-
rently in use.
If the "Autoguidance" application is present, messages
inform you when the correction type changes from Om-
niSTAR® VBS to OmniSTAR® HP/XP/G2 or vice-versa.
The "GPS Status" window also reports which technology
is currently in use.
When you engage automatic steering for the first time
since the display was powered ON, if the OmniSTAR®
HP/XP/G2 signal is not converged, a message displays:
"Using VBS." The message displays just once – when the
system engages.
