Envizio Pro II Field Computers
The Envizio Pro II field computer features a dual frequency DGPS receiver which includes Satellite Based
Augmentation System (SBAS) correction for use with the Wide Area Augmentation System (WAAS) or
European Geostationary Navigation Overlay Service (EGNOS) as standard options. The NovAtel GL1DE
®
feature may be used either in conjunction with a SBAS correction signal as a position smoothing feature or as
an independent correction source for areas with limited SBAS coverage. Both options are available as a
standard feature of the internal dual frequency receiver.
The following optional correction sources may also be used with the Envizio Pro II field computer:
GLONASS. With an optional activation code, the dual frequency receiver may be unlocked to utilize the Global
Navigation Satellite System (GLONASS) satellite constellation which may be used to enhance the standard
GPS satellite coverage.
OmniSTAR. The Envizio Pro II field computer (P/N 063-0173-537) is available with an OmniSTAR capable
receiver for use with an optional OmniSTAR HP or XP subscription. OmniSTAR subscription services
provide an alternative differential source which broadcasts corrections from a worldwide array of reference
sites.
Note:
Contact OmniSTAR for details and subscription information.
Slingshot
®
GS and Satellite GS. GS subscription services offer a decimetric correction source delivered via
either a satellite based correction network or over a wireless network via a Slingshot Field Hub. Contact a local
Raven or Slingshot dealer for subscription details and additional information.
RTK. The Envizio Pro II internal receiver may be upgraded to receive Real-Time Kinematic (RTK) or a
Continuously Operating Reference Station (CORS) network correction services to improve accuracy and
repeatability for precision operations such as planting and strip tilling, or side dressing.
Envizio Pro Field Computers
Envizio Pro field computers feature an internal DGPS receiver which includes Satellite Based Augmentation

e-Dif. An Extended Differential (e-Dif) activation key is available to provide an autonomous correction source in
areas without minimal differential correction systems.
