INSTALLATION

 

Height aiding

 

For operations with weak satellite geometry the position output

 

can be made more accurate by using height aiding. For normal

 

operation height aiding should be set to Filter or Off. When

 

Filter or Fixed is selected, an initial height has to be entered.

 

The value to be entered in Init. height is the GPS height value

 

HGT shown in the position display window no. 1, refer page 36,

 

average over some minutes.

Note!

Height aiding is active only with input of differential GPS.

 

Velocity filtering

 

The HS50 output raw data for SOG and COG with the default

 

velocity filter value set to 3 sec. When smoothing of the SOG

 

and COG measurements are 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.

 

Radar format

 

On the Processing unit terminal P208 output to radar is available

 

(AD-10 format. The default setting is OFF.

 

NMEA ID

 

The NMEA ID for the HS50 output lines can be selected

 

between the following IN, HE, HC, GP and TI. The default

 

setting is IN (Inertial Navigation).

 

Datum

 

For the position Datum, only the WGS-84 is available.
