• Reference to primary GNSS antenna:
o Single frequency - measure to an accuracy of ±0.2 m (~±8 in)
o Dual frequency - (RTK GNSS) measure to an accuracy of
±0.02 m (~±¾ in)
• Reference to vessel - measure to the same accuracy as the
Reference to primary GNSS antenna to prevent a bias in the position
output by POS
• Reference to sensor 1 and sensor 2 - measure to an accuracy of
±0.05 m (~±2 in)
• Reference to auxiliary GNSS antenna:
o Single frequency - measure to an accuracy of ±0.1 m (~±4 in)
o Dual frequency - (RTK GNSS) measured to an accuracy of
±0.02 m (~±¾ in)
• Reference to heave measurement location - measure to an accuracy
of ±0.05 m (~±2 in)
When measuring the lever arm distances, you must resolve them into their
longitudinal, lateral and vertical components using the reference frame. Refer
to the
Theory of Operation description on page B-1 for an explanation of the
various frames of reference used by POS MV.
Additionally, the scalar antenna separation distance should be measured to
an accuracy of 5 mm (~¼ in). You can allow POS MV to measure the antenna
separation distance automatically during its calibration routine; this process
will extend the time it takes the calibration to complete its task successfully.
Record the measurements carefully so that you can use the MV-POSView
Controller program to configure the system. These measurements inform
