INSTALLATION
according to IMO GPS Receiver Equipment approval.
Indication of exceeded HDOP limit will be shown on the
Display unit by a flashing HDOP text behind the time
indication, see the secondary NAV1/POS display on page 46.
Velocity Filtering
The Simrad HS52 outputs raw data for SOG and COG with the
default velocity filter setting OFF. When smoothing of the SOG
and COG measurements is required, the filter period could be
selected in the range 1 to 99 seconds in steps of one second.
With a high filter period more smoothing of the SOG and COG
measurements will be achieved and the response to speed and
course changes gets slow. In general we don't recommend the
use of filter constants above 10s for a moving vessel.
Position Filtering
The Simrad HS52 outputs raw position data with the default
filter setting OFF. When smoothing of the position
measurements is required, the filter period could be selected in
the range 1 to 99 seconds in steps of one second. With a high
filter period more smoothing of the position measurements will
be achieved and the response to position changes gets slow. In
general we don't recommend the use of filter constants above
10s for a moving vessel.
Heading Filtering
The Simrad HS52 outputs raw heading data with the default
filter setting OFF. When smoothing of the heading
measurements is required, the filter period could be selected in
the range 1 to 99 seconds in steps of one second. With a high
filter period more smoothing of the heading measurements will
be achieved and the response to heading changes gets slow. In
general we don't recommend the use of filter constants above
10s for a moving vessel.
Clock Data
On the Processing unit terminal P208, output to radar (AD-10
format) or a 1-second PPS pulse are available. The default
setting is for Simrad radar. Other selections are Furuno, 1PPS
or OFF.
Nmea Id
The NMEA ID for the HS52 output lines can be selected
between the following; IN, HE, HC, GP and TI. The default
setting is GP and the product will then be according to the IMO
GPS Receiver Equipment approval.
