Speed Averaging - Furuno GP-1610CF Operator's Manual

UNHEALTH: Every GPS satellite is broad-
casting abnormal satellite number(s) in the
Almanac. Using this information, the GPS
receiver eliminates any malfunctioning satel-
lite from the GPS satellite schedule. Once the
malfunctioning satellite is returned to on-line
status it is automatically restored to the satel-
lite schedule when the Almanac is received.
In some instances however the Almanac may
not contain information which announces that
a satellite is now back on line. If you hear of
this through another source, you can manu-
ally restore the satellite to the satellite sched-
ule. Conversely, you can manually disable a
healthy satellite if you hear it is unhealthy.
To restore or disable a satellite, select RSTR
or DISABLED on the UNHEALTH line and
then enter satellite number.
TIME DIFF (using local time): GPS uses
UTC time. If you want to use local time, en-
ter time difference between local time and
UTC time here. The
nate plus or minus time. See the World Time
Standards chart on page A-3 for time differ-
ences.

11.2 Speed Averaging

Calculation of ETA and TTG is based on an
average ship's speed over a given period. If
the period is too long and the ship's speed is
changed suddenly, calculation error will re-
sult. Speed averaging may be increased or
decreased to offset calculation error. The de-
fault setting is 00.
