R40 Mk IIIAIS Base StationThe new R40 Mk III AIS Base Station from SaabTransponderTech is a result of our on-goingefforts to enhance all our products. The R40 MkIII is equipped with a new Base Station Controller(BSC) which hosts the valuable new featuresand it is designed to allow for future expansion.With the R40 Mk III, Saab TransponderTechcontinues to hold its leadership in AIS technology.The R40 Mk III is of course compliantwith the R&TTE Directive and is like its predecessorstype approved by BSH with referenceto AIS Base Station Standard IEC 62320-1.The R40 Mk III AIS Base Station is the maincomponent of a Physical AIS Shore Station asdefined by IALA. Its main purpose is to receivedata from and transmit data to AIS equippedvessels, travelling within the coverage area ofthe Base Station. This enables monitoring ofships´ movements and status in real time.The R40 Mk III can either be installed as standaloneor be integrated into a network, suchas the market leading AIS Network and theCoastWatch AIS monitoring and control suiteby Saab.• Type approved by BSH according to IEC62320-1 test specification for AIS BaseStations• Compliant with R&TTE Directive• Third generation of AIS Base Station fromSaab using the latest technology• Excellent performance and reliabilitythrough joint development with airborneproducts• Supports fully redundant configurations byadvanced embedded Hot Standby functionality• Full remote configuration and monitoring• Advanced Windows based configurationand monitoring tool software includedThe R40 Mk III Base Station maincharacteristics• Outstanding receiver sensitivity: Betterthan -111 dBm• Embedded Base Station Controller,enhancing functionality and flexibility• MTBF >100 000 hours• Reception and transmission of all applicableAIS messages• Internal memory for storage of data,variable size up to hundreds of GB• Built-in Web Server• AD-converter• SNMP support• Selected by the majority of Maritime administrationsand Port Operators throughoutthe world
SECURITY SOLUTIONS• Autonomous channel managementcapability for different geographical areas• Hot Standby functionality• Repeater functionality includingrepeat filtering• Receive only mode• Built in support for automatic transmissionof AtoN reports (message 21) incl.information on offshore obstacles, e.g. oilplatforms, wind farms etc.Optional functionality• Separate receive and transmitantenna interfaces• Built in Reference GPS receiver,makes it possible to internally generatedifferential GPS corrections that canbe transmitted on the AIS channels• Third AIS receiver available for localuse and special applications• 1 PPS input for external timing• Special periodic repeat functionality ofreceived AtoN reports• Advanced evaluation of the AIS Data Linkstatus such as SNR, RSSI, link load etc.• Channel management via DSCDESIGNThe R40 Mk III main parts are the VHF transceiver,GPS receiver, Radio Controller and a BaseStation Controller. The transceiver unit containsthree independent VHF receivers and one commontransmitter which alternates its transmissionsbetween the used channels. The internal GPSreceiver’s main task is to provide accurate timesynchronization. Several external interfaces areavailable, see specification.TDMA/DSC TransmitterAISBase StationT/R SwitchTDMA ReceiverTDMA ReceiverTDMA ReceiverRadio ControllerBSC(Base StationController)GPS ReceiverAISNetwork
SECURITY SOLUTIONSBuilt in WEB-server for monitoringand controlThe R40 Mk III has a built-in web server thatallows the user to connect to the R40 Mk III viaa standard WEB-browser. It allows for quick andeasy access to basic monitoring functions such asalarms, GPS functionality, VDL link status, etc.The PSS Configuration and Monitoring Tool whichis supplied with the R40 Mk III should be used formore advanced configuration and monitoring.Status monitoring via SNMPThe R40 Mk III is an SNMP enabled device whichallows it to be remotely monitored by an SNMPManager. The SNMP agent is embedded in the R40Mk III. Properties that can be monitored in thebase station are alarms status, input voltage, channelload, used satellites, number of satellites found,hot-standby status, connection state, etc.External Timing IRIG-B 003The R40 Mk III can use an external UTC source, inorder to facilitate installations where the internalGPS cannot be used for synchronization or wherea synchronization backup is required. The externalUTC source can either provide a 1 PSS signaland NMEA time messages or it can be an IRIG-B003 digital time signal. The IRIG-B 003 format isinternationally recognized to provide accurate andconsistent timing information.AD-converterThe built in AD converter allows for connectionof external equipment, e.g. sensor for temperature,humidity, wind speed or battery monitoring. Thevalues read are available on the Ethernet port.Internal Memory for temporarystorageThe R40 Mk III includes built in non-volatilememory for temporary storage of VDL and statusdata. This function is used if the base stationtemporarily loses its connection to the AIS network.When the network connection is restored, the temporarilystored data are automatically transferredfrom the internal base station memory to the AISnetwork for storage in a database. The data transferis a mix of real time information and stored data.Real time data has the highest priority and storeddata are transferred when there is available capacityon the network connection. The standard size ofinternal storage memory is 4 GB FLASH but canbe expanded to several hundred GB. A memory of4 GB gives a storage capacity of approximately 45days assuming an average VDL load of 40%.
SECURITY SOLUTIONSTypical site installationThe R40 Mk III is designed for the highest availabilityand reliability, resulting in high performanceand long trouble-free operation. Additionally it ispossible to connect two R40 Mk III in a Hot Standbyconfiguration without adding any extra hardware.Several important parameters are continuousilyevaluated in order to monitor the status of the units.This includes for example VSWR and VHF transmissiondata. The standby unit immediately takesover if a fault is discovered. The picture below showsa typical installation on a Base Station Site, two R40Mk III in Hot Standby, uninteruptable power supply(UPS), Ethernet switch and cavity filters.Configuration & Monitoring ToolThe R40 is delivered with an advanced Windowsbased Configuration & Monitoring tool, PSS Tool. Itis used for monitoring and configuration of theR40 Mk III AIS Base Station. Examples of operationsperformed by PSS Tool are configuration, upload ofnew software and monitoring of base station status.The PSS-tool can be used locally connected directlyto the R40 or remotely via a TCP/IP network.General ConfigurationThe picture below displays the main configurationpage in PSS Tool which is used to set the basic configurationof the R40 Mk III.VDL Link Map ViewerPSS Tool provides a graphical view of the AIS VDLLink displaying sent/received messages and reservations.The user can select specific slots to view detailedinformation on what unit is using the slot andthe type of message.
