Tools Menu

Differential

Select the Differential icon from the GPS menu to set up the internal receiver for the desired GPS correction

source. Generally, the SBAS (WAAS/EGNOS) option is selected by default.

Note: Touch the ‘Auto Detect’ button on the GPS Health screen if a Raven receiver is connected directly

to the ‘GPS Receiver/DGPS’ port on the chassis interface or main interface cables. If the field

computer detects a Raven receiver, the field computer can be used to select the differential source

and PRN of the external receiver.

If GPS is routed through an automated steering system such as the Raven SmarTrax or

SmartSteer, the receiver cannot be configured with the field computer.

Elevation Mask

The elevation mask sets the minimum elevation of a satellite above the horizon which the field computer may

use for differential correction. This value is displayed in degrees above horizontal.

Touch the Elevation Mask icon in the upper, right corner of the Differential screen and use the on-screen

keypad to modify the elevation mask setting. The default value for the elevation mask is 4.0.

The current elevation mask value is displayed on the GPS Health screen.

SBAS (Satellite Based Augmentation System)

Note: Some Envizio Pro field computers may have an internal receiver enabled for e-Dif and L-Dif only.

These receivers do not have an SBAS option and will not be able to utilize SBAS correction

signals.

Select the SBAS option to utilize the Wide Area Augmentation System (WAAS) or European Geostationary

Navigation Overlay Service (EGNOS) correction signals. For most internal GPS receivers, this is the default

option selected. An optional Global Navigation Satellite System (GLONASS) authorization key is also available

to enhance the standard GPS satellite constellation. This key allows the dual frequency receiver to utilize the

GLONASS satellite constellation which can increase the number of satellites visible at any given time and help

improve satellite coverage.

Note: The GLONASS satellites will be utilized when set to SBAS or RTK correction sources.
