RadaScan Operator - 3Welcome to the RadaScan position reference sensor for dynamic positioningand other vessel control applications. RadaScan is a high accuracy radarbased sensor that provides positional information to allow automatedapproach and/or station keeping relative to a structure or vessel. Thestructure or vessel must be equipped with one or more retro-reflectiveRadaScan transponders/targets.Components:RadaScan has been designed for permanent installation and quick/easyoperation. A RadaScan system comprises of 3 major components as follows:•The RadaScan Sensor. A scanning transceiver unit with integral power supply and processing electronics for installation in a prominent external location in order to view available transponder. The Sensor is connected to the vessel DP system by a serial RS422 or Ethernet link.•The RadaScan Console. A system control and display application running under Microsoft Windows XP on a standard PC. This allows full control of the system together with graphical and data display of system status. An Ethernet link connects the Sensor to the Console PC.•RadaScan Transponder/Target.A passive self contained battery powered electronics module for temporary, semi-permanent or permanent installation on the target vessel. RadaScan transponders are ATEX certified as intrinsically safe.Principles of OperationThe RadaScan sensor emits a low power radar beam. The beam is receivedby a RadaScan transponder and instantaneously reflected back to the sensor.The sensor uses the reflection to accurately calculate the distance (range) anddirection (bearing) to the transponder. This positional data is automaticallysent to the DP system. The transponder reflection is retro-reflective incharacter (ie it is sent in the same direction as received beam). Thetransponder is also able to encode the reflection with a transponder identitycode. This code allows the sensor to recognise the reflection as genuine andso aid easy operation and improve tracking reliability.RadaScan unitRadaScan equipped vesselRadaScan transpondersIntroductionRadascan Operators Manual 20/11/06 1:46 pm Page 3

RadaScan Operator - 7Reflections and targetsReflections from targets are shown as yellow squares on the seascape. Thesignal processing in RadaScan ensures that only reflections from genuinetargets can be recognised and displayed. When navigating a coloured box isdrawn around the reflection square to show the quality of the association witha known target. This circular area is a seascape and shows the relationship between theRadaScan vessel and the targets. There are a number of key elements withinthe Sensor display:RadaScan vesselThe RadaScan vessel image is shown, as determined by the setting in theDisplay options, either as an outline or a solid filled shape, with a distinct bowand stern, or alternatively the vessel image may be switched off - see Displayoptions.Depending upon the chosen display option, the centre of the Sensor displaywill either represent the RadaScan vessel, or the target origin of the currentmulti-target group - see Display options.. Range circlesA series of radiating labelled concentric circles provide a visual indication of thelocation of the RadaScan vessel to the targets. Use the Zoom in and Zoom outbuttons to change the scale of the display.Target reference frameIndicates the A-B axis that the RadaScan system uses to define the positions ofeach target. This axis can be included/excluded from the display as required -see Display options.Sensor displayRadascan Operators Manual 20/11/06 1:46 pm Page 7

RadaScan Operator - 9The upper right of the screen provides positional information whenevernavigation mode is being used. Positional Display:A number of different DP message types are available for configuration duringinstallation and commissioning. The DP message type defines the positionaldisplay format.In most formats the Range a Bearing to the primary target from the vessel isdisplayed numerically. Heading is only available when a NMEA message formatis used and where 2 or more targets are available and multi-target navigation isselected.When a NMEA format is used to navigate in Single target navigation the Rangeand Bearing values can be converted and displayed as Bow and Starboarddistances from the target to the vessel. The option is selected by un-ticking the Range & Bearing box in the Configuration property page.When a NMEA format is used to navigate with multiple targets the Range andBearing values can be converted and displayed as the vessel position in relationto the A and B axis of a co-ordinate frame constructed around the target group.The option is selected by un-ticking the Range & Bearing box in theConfiguration property page.Positional displayDP Feed modeInformationQuality IndicatorNavigation sectionInformation Quality IndicatorA graphical 9 bar display gives a quick indication of the confidence that thesensor system has in the positional data being generated. The more bars thatare displayed the better the data. The bars and numerical values are alsocoloured and change from red through orange to green as the date improves.Navigation: modesYou can choose from two main modes of navigation:Single target navigationSingle target is the simplest type of navigation as it only requires a single targetand does not involve the creation of a target group. It is quick and easy to usehowever be aware that this method has certain limitations as follows:• If the true target reflection is obscured by vessel operations there is apossibility that the sensor track will be lost and navigation will drop out.• There is no provision for Heading data to be produced.Multi-target navigationThe use of multiple targets gives certain advantages over single targetnavigation and is worth considering whenever suitable targets are available.The advantages are as follows:• Improved tracking stability• Redundancy allowing temporary loss of target reflection.• Provision of Heading data in relation to target group.Radascan Operators Manual 20/11/06 1:46 pm Page 9

RadaScan Operator - 13Alarms property pageDuring operation, the RadaScan system produces an event audit trail in theform of alarms from its various constituent components. These range inincreasing order of severity from: Information, Warning, and Error to Fatal. Asthese alarms are received from the sensor, the console application lists themwithin the Alarms page tab of the property sheet. To assist with quick recognition of the various alarm types, a colour codingscheme is employed. The triangular and square symbols used to represent thestart and stop points of each alarm condition are represented in three coloursto indicate their severity:• Information Grey • Warning Orange • Fatal and Error Red As an alarm condition occurs, its entry is appended by a Start symbol in therelevant severity colour. When the condition is resolved, the entry is appendedwith a Stop symbol.The Pause symbol is displayed in the event of a single non-persistent incidentThe Alarms page offers two key features to assist in the display of applicablealarms. These are the Alarm filter and the Alarm History.Using the alarm filterThis allows you to choose which types of alarms (of the four categories) todisplay within the Alarms page. As standard the filter is activated with only the'Information' alarms un-ticked to conceal them. To use the alarms filter:1 View the Alarms page within the Property sheet (in the lower right corner).2 Click the right side of the two-part filter button. A drop down list will bedisplayed showing the four types of reports/alarms.3 Click on each type of alarm to check/uncheck them as necessary - Note: Alarm types that are ticked are shown in the alarms list, un-ticked items are hidden.4 To enable/disable the filter, click the left side ofthe two-part filter button. The filter is activewhenever the right side of the filter button is'pressed in'.Alarms page - Lists any messages received from the various component unitsof the RadaScan sensor. These are classified into four types of alarm which are,in increasing order of severity: • Information - grey symbols • Warning - orange symbols • Error - red symbols • Fatal - red symbols A filter is available tosuppress the display ofparticular alarm types.As standard, the filteris activated and theInformation messagesare hidden from thelist. Deleting alarms fromthe current list willmove the alarms to theHistoric list. Deletingthem from the Historiclist will discard thempermanently. The arrow symbol indicates the Startof an entry that persists, while thesquare symbol indicates the end ofan entry. The pause symbol indicatesan entry that does not persist.Radascan Operators Manual 20/11/06 1:46 pm Page 13
RadaScan Operator - 14Using the historic alarm listThe Alarms page has two alarms lists. The 'Current' list is where new alarmreports (since the last start of the console software) are automatically stored asthey occur. In addition, a 'Historic' list allows you to clear the Current list andtransfer its alarms so that you do not lose potentially important diagnosticfeedback. On shutdown, current alarms are automatically transferred to theHistoric list.To accept alarms in the current list1 View the Alarms page tab within the Property sheet and check that the 'Select Log Type' entry shows 'Current'. 2 Select the alarms that you wish to move into the Historic list:• To accept one alarm - click the alarm entry and click the button.• To accept two or more - hold down the CTRL key, click the required alarm entries and click the button.• To accept all alarms - click the button. Note: If you attempt to transfer any alarms that are still unresolved, a warningdialog will be displayed.

RadaScan Operator - 15Reflection Property pageThis area of the RadaScan User Console screen provides detailed informationon a number of different topics. The property sheet uses tabbed pages togroup information and has four tabs: Reflections page - Provides a numeric list of the reflections received during thelast complete revolution of the sensor rotor. This page can be used to verify thegraphical representation of reflections shown within the Sensor display.As a new revolution is started, the list is cleared and starts again. For eachverified reflection the list provides: Target ID code, Range, Bearing and Signalto Noise Ratio. The latter relates to the quality of the reflection. For changes upto 200m this value will ideally be between 13 and 21. Radascan Operators Manual 20/11/06 1:46 pm Page 15
RadaScan Operator - 16Configuration property pageThe Configuration page provides a mixture of RadaScan sensor data fortroubleshooting purposes and also offers three selectable options: •Day View/Night View - This option is essential in maintaining optimum usability between day and night operations.•DP Feed Format & Message String - This is key to correct operation but which does not usually require alteration during day-to-day operations.•Range & Bearing Only - In Single Target navigation with NMEA feed types,the default is to display position in a Bow Starboard axis frame. This optionswitches the display to one of Range and Bearing to the selected target. Toimplement, tick the box and click the apply button. The DP message string is unaffected.Day View/Night ViewTo provide maximum visibility during daytime operation and minimal glareduring night shifts, RadaScan User Console offers two display modes: 'DayView' and 'Night View'.To change the view mode:1 View the Configuration page within the Property sheet.2 Click the down arrow of the view box to reveal a drop-down list with two options.3 Select the appropriate display format and then click the button.'Day' colour contrast setting'Night' colour contrast settingRadascan Operators Manual 20/11/06 1:46 pm Page 16
RadaScan Operator -17DP feed format & message stringThis option controls the format in which the positional information is packagedand sent to the vessel's DP system. The DP Feed Format may only be changedwhen RadaScan is not navigating. Any changes to this setting MUST be carriedout in conjunction with a similar change on the DP system - both systems mustuse exactly the same format and variant thereof. The choice of DP Feed Formatcan have an effect on the information displayed in the Navigation section (topright corner) of the Console screen. The DP Message string field displays the current text being sent to the DPsystem based on the current selection of the DP Feed Format type.To change the DP feed format:Note: Changes in formats, other than between NMEA and ASCII, can only becarried out in service access mode.1 View the Configuration page within the Property sheet.2 Click the down arrow of the DP Feed Format box to reveal a drop-down listof options.3 Select the appropriate format and then click the button. Ensure that the DP system is correctly prepared to receive the new message format.Single Target Display - Range & BearingThe default display mode forSingle Target is to present theposition of the sensor vesselin metres along Bow andStarboard axes with origin atthe target. By selecting the Range &Bearing option on theConfiguration page, thedisplay is changed to thedistance and the bearing ofthe target from the vessel.Note: Selecting either optionhas no effect on the messagestrings that are sent to the DPsystem.
