Simrad SIMRAD HS50 manual Height aiding, Velocity filtering, Radar format, Datum

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.
