11.8.1 Heading Averaging Mode
Selecting this option allows you to tell the system the frequency you wish to
have
the heading updated. There are three options:
1. Automatic: When you select automatic the frequency of your heading is
updated by
speed. The faster you are moving the faster a new heading is obtained. If you
are
moving slowly, it takes more time to update your heading.
2. Instantaneous: This option will get the heading directly from the receiver.
This
gives you the fastest heading updates but due to GPS fluctuation this also has
the
highest probability of being incorrect.
3. City (Urban Canyon): This option is the slowest at updating your heading.
Use this
option in cities like New York or San Francisco. Selecting this mode in
conjunction
with the "set GPS heading mode" may help maintain a direction of travel when
experiencing
the urban Canyon effect.
