The Field Hub is designed to provide RTK (Real Time Kinematic) corrections
to a dual band DGPS receiver via a cellular or wireless service provider. The
DGPS receiver must be capable of receiving RTK correction messages in
either CMR+ or RTCM v3 format via a serial cable or RS-232 adapter cable.
Note: A cellular or wireless service provider and a Slingshot™ subscription
are required to utilize RTK corrections through the Field Hub.
Devices with web or internet capability (i.e. Raven field computer) may
connect to the internet via the ethernet connection on the Field Hub.
When used with a Raven field computer, the Field Hub may be used to
transfer data such as prescription or coverage maps from the field computer
to a home or office computer via the Slingshot web site.
Note: A user account will be necessary to access the Slingshot web site.
Contact the Raven Applied Technology Division Product Support
Group to set up a user account.
Updates
Any updates for the Raven Field Hub will be automatically transferred via an
active wireless connection.
Installation
Best Installation Practices
• The Field Hub is not weatherproof. Mount the Field Hub inside of the
vehicle cab or operator's compartment.
• Mount the Field Hub in a location where it will not be kicked or jarred during
normal equipment operation and ensure the status LED's are viewable.
• Do not route cables through potential crimp points such as vehicle doors or
windows.
• Verify cable length before mounting or placing any hardware.
• The GPS patch antenna and cellular antennas should be mounted as high
as possible using the magnetic bases.
Aerial antenna mounting plates are supplied and may be used if a suitable
magnetic mounting location is not available. Be sure to thoroughly clean
and dry the mounting location before applying the adhesive backing.
• The cellular antennas should be spaced with 3 - 8' [1 - 2.4 m] between the
antennas. It is not necessary to orient the cellular antennas with the
direction of travel or on the vehicle.
• Do not connect the Field Hub power leads directly to the vehicle battery.
Note: Refer to the
diagram.
To install the Field Hub™:
