[DISABLE SATELLITE(SBAS)], [DISABLE SATELLITE(QZSS)]: Every GPS satellite
is broadcasting abnormal satellite number(s) in its Almanac, which contains general
orbital data about all GPS satellites. Using this information, the GPS receiver automat-
ically eliminates any malfunctioning satellite from the GPS satellite schedule. Howev-
er, the Almanac sometimes may not contain this information. You can disable an
inoperative satellite manually. Enter satellite numbers (up to three satellites each for
SBAS or QZSS) in three digits.
[COURSE UP REDRAW ANGLE]: Sets the angle to redraw the course in the AC up
mode (20 to 60°). See section 2.4.
[FREE UP ANGLE]: Sets the angle which points to the top of the screen in the Spec-
ified direction up mode. See section 2.4.
[COURSE SMOOTHING]: During position fixing, ship’s course is directly measured by
receiving GPS satellite signals. The raw course data may change randomly depend-
ing on receiving conditions and other factors. You can reduce this random variation by
increasing the smoothing. Like with latitude and longitude smoothing, the higher the
course smoothing the more smoothed the raw data. If the setting is too high, however,
the response to speed and course change slows. For no smoothing, enter all zeroes.
[ROLLOVER]: No use.
[RTE SENTENCE]: Selects RTE sentence mode from [LEGACY] or [DNV].
