D. S. C. / A. I. S. • D. S. C. – Digital Selective Calling • A. I. S. – Automatic Identification System

D. S. C – Digital Selective Calling • • VHF Radio receives position data from GPS or Chartplotter Get MMSI (Maritime Mobile Service Identity) from ICASA. org. za Program MMSI into VHF On activation, VHF broadcasts SOS, Position and MMSI number. OR

A. I. S. - Automatic Identification System • Receiver – Collects AIS information from VHF and sends it to the Chartplotter/Display • Class A – Receives and Broadcasts, 12 Watt output every 2 -10 seconds, sends more vessel information and has more in- and output ports than Class B • Class B – Receives and Broadcasts, 2 Watt output every 30 seconds, sends only vessel ID and “motion” information, communicates on NMEA 1830 (2000 on very new models)

A. I. S. • AIS takes information from VHF and GPS and then sends information to chartplotter “Apples to apples” installation

RADAR

• Ben Ellison – Panbo. com

Pulse vs Broadband Radar • Pulse – Traditional, radar as we know it. • Broadband – FMCW – Frequency Modulated Continuous Wave • Uses 2 arrays mounted vertically, one sending, the other receiving. • Instead of receiving a return from a single pulse, FMCW technology constantly builds up radar return energy. Resulting in superior target definition (especially at close range)

Advantages/Disadvantages of Broadband Radar • • • Very good at close range (1/32 NM) Safer (1/2000 th output) – much disagreement Lower DC power draw Radar continually tunes itself No Tuning/warm up time • • Not as effective over 15 NM Won’t trigger RACON buoys Size Only available from Navico – Lowrance, Simrad and Northstar

MFD’s Multi Function Displays

INPUTS • • Charting Software Broadband Hi-Def Radar Broadband Depth Weather Hi - Def and Infra-red Cameras Sensor and Systems Information Multimedia

Touchscreen: • Raymarine E-Series and Garmin 5000 and 7000 • Furuno and Navico do not offer touchscreen

Radar Overlay • Only Furuno and Garmin can overlay Radar on 3 D charts

Best at showing weather • Raymarine and Furuno show rain best, although the Furuno UHD is much more expensive

Best at Broadband • Of the Navico MFD’s – Simrad’s NSE

MARPA Mini Automatic Radar Plotting Aid • Only offered on the Simrad NSE, Raymarine and Garmin MFD’s, not on Furuno True Wakes/Echo • Only Furuno and Raymarine, not on Garmin or Simrad

Furuno True Motion Echo

Garmin MARPA

Raymarine with True Wakes and MARPA

PLB’s Personal Locator Beacons • Three main types - EPIRB, EPIRB with GPS, GPS • Spot - 406 MHZ with GPS and Globalstar messaging, SAR by company • ACR mini B -121. 5 MHZ and 406 MHZ, non GPS, SAR by USCG/AMVER • Mc. Murdo - 121. 5 MHZ and 406 MHZ, GPS, AMVER SAR • ACR Aqualink - 121. 5 MHZ and 406 link, with I'm OK and Aquaview LED test function, AMVER SAR

Spot Locator ACR Mini B Mc. Murdo Fast. Find ACR Aqualink

MSLD’s Marine Survivor Location Devices • Sea. Marshall - base unit and PLB, extensive commercial use • Mobilert - transmitter activated by water, generates GPS tag • Firstlight Mermaid ID - base, thru hull and ID -pods, water activated, generates GPS tag • Alert 2 - As above with optional R. D. F kit • Raymarine Lifetag - tag activated by distance, sounds Seatalk alarm, records position and creates mob target on all Seatalk devices, lowers range on chartplotters and radars to optimum for MOB/SAR, up two 16 tags per base station.

Caveat’s: Beware of the Blackberry Effect Remember that all of these things we’ve discussed tonight are electronic aids to navigation and cannot replace your eyes, ears, a compass and paper charts as your primary forms of navigation
