6.2.1.5.1.6 Heading Compensation for REPEAT-FUNCTION: LAST VALUE
COMPENSATION
The bearing result is always a relative bearing referring to the
antenna´s longitudinal axis. If compass information’s are available, the
bearing result can be converted to a direction, referring to north,
independent of the antenna axis.
NOTE
The LED-circle will always indicate the relative bearing.
If now activating the REPEAT-function (showing the last bearing result – see 5.2.8), the
displayed bearing value is the relative bearing value with the vehicles heading at the time when
the last bearing signal was received. If there was a change of heading after the last bearing and
after activating the REPEAT-function, the indicated bearing value has lost its meaning
completely.
If compass data are available (external or internal), the change of heading can be measured. If
activating now the REPEAT-function, the indicated value will be corrected for the present
heading.
NOTE
There will only be compensated changes of heading of the own vehicle. Changes of bearing
angles, caused by a change of position of the bearing or transmitting station will - of course - not
be considered.
