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
