Vector VR1000 GNSS Receiver Quick Reference Guide (QRG)

Environmental
Hemisphere Vector GNSS Receivers are designed to withstand
considerations
harsh environmental conditions; however, adhere to the following
limits when storing and using the VR1000:
• Operating temperature: -40°C to +70°C (-40°F to +158°F)
• Storage temperature: -40°C to +85°C (-40°F to +185°F)
• Humidity: IEC 16750-4:2010 Section 5.6 Humid heat, cyclic test
Mounting
The VR1000 outputs heading, pitch, and roll readings regardless of
orientation
the orientation of the VR1000. The relation of the antennas to the
machine's axis determines if you need to enter a heading, pitch, or
roll bias. The primary antenna is used for positioning and the
primary and secondary antennas, working in conjunction, output
heading, pitch, and roll values.
Parallel
Install the GNSS antennas parallel to, and along the centerline of the
orientation
axis of the machine. This provides a true heading. In this
orientation:
• If you use a gyrocompass and there is a need to align the
antennas, you can enter a heading bias in the VR1000 to calibrate
the physical heading to the true heading of the machine.
• You may need to adjust the pitch/roll output to calibrate the
measurement if the receiver is not installed in a horizontal plane.
Perpendicular
Install the GNSS antennas perpendicular to the centerline of the
orientation
machine's axis. In this orientation:
• Enter a heading bias of +90° if the secondary antenna is installed
on the right side of the machine, and -90° if the secondary
antenna is installed on the left side of the machine.
• Configure the receiver to specify the GNSS receiver is measuring
the roll axis using the VR1000 WebUI.
• Enter a roll bias to properly output the pitch and roll values.
• You may need to adjust the pitch/roll output to calibrate the
measurement if the receiver is not installed in a horizontal plane.
