    Simrad HS52 GPS compass and DGPS navigator is possible to output 1PPS time tag messages from HS52. This message is the ZDA 1 Hz format and is selectable as output format in the Data Output 1 and 2 menu. Select 1PPS as clock data format in the General setup menu to activate 1PPS signal output on the P208 connector.

  • Page 33: External Alarm

    To comply with the IMO Transmitting Heading Device type approval (not mandatory for GPS Receiver Equipment approval), the Simrad HS52 has to be connected to an external alarm. This since the acoustic alarm in the Display unit is not within the required minimum level of 75 dB. Therefore the Processing unit has built-in alarm functionality.

  • Page 34: Software Setup Procedure

    Software Setup Procedure This chapter describes a number of basic installation settings that must be performed as part of the Simrad HS52 installation. Some of these settings may also need to be changed during operation. In addition to the basic installations settings, a number of advanced setting are available.

  • Page 50: Turning The System On/Off

    Since there normally is no reason for turning the unit off, it should be left running continuously. The HS52 will be shut down in a controlled way when the button is pressed for 1-2 seconds. Then the message POWER Shutdown in process will appear on the screen.
  • Page 51 SOG is calculated (one black bar graph) or not (one white bar graph). The Simrad HS52 GPS receivers include a RAIM exclusion and detection algorithm implemented to detect satellite failure. The RAIM algorithm is implemented as described in "Guidelines for the use of differential GPS in offshore surveying".
  • Page 52 Simrad HS52 GPS compass and DGPS navigator The integrity indication for different position accuracy levels are expressed in three states that satisfies the requirements in IEC 61108-1 second edition 2003-07. The states are Safe, Unsafe and Caution. On the display, the visual indicators are shortened into SAFE, CAUTN and USAFE.

  • Page 53: Navigation/Hdt Display

    Primary NAV1/HDT display, shown after the start-up screen when the HS52 is turned ON. True heading is shown as a big number in the centre of the compass with the COG value above it.

  • Page 54: Navigation/Pos Display

    The third display appears when pressing the NAV1/POS button three times. This display shows satellites in sight by the Sensor unit, and which satellites the Simrad HS52 is tracking. The satellites are presented according to satellite geometry. The bars on the left side of this display indicate the signal-to-noise level for each satellite.
  • Page 55 Shows the average signal-to-noise ratio on GPS receivers 1 and 2. Correction age Indicates the age of differential corrections. If Simrad HS52 receives no differential correction, the displayed correction age will be high. See No Differential Corrections on page 60 for troubleshooting loss of differential signal.
  • Page 56 The other information in this display is only of interest to service personnel. In the SBAS page information of which SBAS system used by the Simrad HS52 is presented together with the selected satellite by its PRN number, the message rate of this satellite and status on SBAS warnings.

  • Page 57: Alarms

    Sensor unit status. The Sensor unit status is mainly used by service personnel. Alarms The Simrad HS52 will generate three types of alarms. These are position, heading and no data alarm. It is possible to enable the heading alarm and the position alarm individually and to set all alarms enabled or all alarms disabled.

  • Page 58: Position Alarm Display

    The alarm text will remain in the display until the NAV1 or NAV2 button is pressed. No heading data will be output from HS52 and shown on the display as long as the heading alarm situation is present. The last valid position determined will be output from HS52 and shown on the display as long as the position alarm situation is present.

  • Page 60: Watchdog

    If so, a message will appear after restart on the display indicating this (system restart). Operation The HS52 will normally output signals on the serial lines without any involvement from the user. However, the following should be taken into consideration during operation: Adjust Backlight on Display The rotary knob is used for adjusting the display brightness.

  • Page 61: Height Aided Gps Position

    OPERATING INSTRUCTIONS Use of SBAS Corrections It is possible either to specify which Geo satellite to track or to let the receiver choose which Geo satellites to track using Automatic mode. However, it is recommended specifying which Geo satellites to track. This enables the receiver to keep better track of the specified satellites without starting to search for PRN numbers every time it looses track of the satellite.
