Comments
• It is recommended to use a baseline elevation offset as
close as possible to zero and a baseline azimuth offset as
close as possible to n×90 degrees.
• If the azimuth offset is close to 0 or 180°, then the
vehicle's pitch and heading will be estimated and output.
• If the azimuth offset is close to 90 or 270°, then the
vehicle's roll and heading will be estimated and output.
• If the azimuth offset from either North, South, West or
East exceeds 15 degrees, then the receiver delivers the
heading component of attitude, but does not output pitch
and roll.
• If the elevation offset is greater than 45 degrees or less
than -45 degrees, then the receiver considers installation
to be invalid and does not output any attitude information
(i.e. no pitch, no roll and no heading).
• The specified values of offsets are used only when the
rover is operating in heading mode.
• Sending the command without f1 or f2 will not change the
corresponding offset value currently used, which will stay
either that entered previously through a valid CPD,ARR,
OFS command, or 0° (default value) if no such command
was run.
• With “Antenna 1” connected to the GNSS input and
“Antenna 2” connected to an external GNSS receiver
providing its corrections through a specified port on your
receiver), the heading will describe the direction of the
vector connecting Antenna 2 (vector origin) to Antenna 1.
