Part 3: Principle Of Harmonic Constants.
Important Definitions:
1.    Bore Tide: As A Progressive Wave Enters Shallow Waters Its Speed Decreases. Since The Trough Is Shallower Than The Crest Retardation Is Greater Resulting In The Steepening Of Wave Front So In Estuaries Advance Of Trough Is So-Much Retarded That The Crest Of The Rising Tide Overtakes It And Advances Upstream In A Churning Wall Of Water.. Dangerous For Moored Ships Which Can Surge.
2.    Chart Datum: Lowest Astronomical Tide Below Which The Level Of Water Doesn’t Usually Fall.
3.    Negative Surges: Fall In Low Water Or Predicted Water Due To Meteorological Reasons.
4.    Seiches: Occurs In A Confined Body Of Water. A Long Wave Having Crest At One End And Trough At Other End Of Confined Space.Abrupt Changes In Meteorological Conditions Like Passage Of An Intense Depression Or Line Of Squall May Cause Oscillations Of Sea Level, So The P0eriod Between Successive Waves Can Be Unpredictable, Few Minutes To Two Hours.

Ballast water management plan;
Harmful Aquatic Organisms In Ballast Water
An Mepc Working Group On Ballast Water Reported Progress In Developing Draft New Regulations For Ballast Water Management. It Is Intended To Include These In A New Annex To Marpol, To Be Adopted At A Conference Provisionally Scheduled For 2000. Implementation Guidelines For The Proposed Annex Are Also Being Developed, Which Are Expected To Be Included In A Code Related To The New Annex.
The Proposed New Annex Vii Is Aimed At Addressing The Environmental Damage Caused By The Introduction Of Unwanted Aquatic Organisms In Ballast Water, Used To Stabilize Vessels At Sea. Globally, It Is Estimated That About 10 Billion Tonnes Of Ballast Water Is Transferred Each Year.
The Water Taken On Board For Ballasting A Vessel May Contain Aquatic Organisms, Including Dormant Stages Of Microscopic Toxic Aquatic Plants - Such As Dinoflagellates, Which May Cause Harmful Algal Blooms After Their Release. In Addition, Pathogens Such As The Bacterium Vibrio Cholerae (Cholera) , Have Been Transported With Ballast Water. As Ships Travel Faster And Faster, The Survival Rates Of Species Carried In Ballast Tanks Have Increased. As A Result, Many Introductions Of Non-Indigenous Organisms In New Locations Have Occurred, Often With Disastrous Consequences For The Local Ecosystem - Which May Include Important Fish Stocks Or Rare Species.
The Mepc Approved A Questionnaire To Be Sent To Member States To Obtain Information On Current Domestic Laws And Regulations On Ballast Water Management. It Is Intended That The New Internationally Binding Regulations Would Avoid A Situation Whereby Individual Governments Adopted Their Own Rules To Prevent Contaminated Ballast Water Affecting Their Local Ecosystems. Meanwhile, The Mepc Noted The Different Options For Introducing The Proposed Regulations. The New Annex To Marpol, As Originally Proposed, Could Be Adopted Via A Protocol To Add A New Annex To Marpol 73/78, Or It Could Be Adopted As A New Annex Via Amendments To Marpol 73/78, A Simpler Process. Another Option Is For A Diplomatic Conference To Adopt A New Convention On Ballast Water Management, Under Which The Terms For Entry Into Force Would Be Determined By The Conference, Instead Of Having To Comply With Existing Entry Into Force Terms Established By Marpol 73/78. The Mepc Agreed To Consider A Legal Framework For The New Regulations At Its Next Session In November.

Marine Environment Protection Committee 40PthP Session 18-25 September 1997
Committee Tackles Ballast Water Problem
The Committee Discussed Measures To Deal With The Problem Of Harmful Aquatic Organisms Transported In Ballast Water And Approved A Draft Assembly Resolution On Guidelines For The Control And Management Of Ship’s Ballast Water To Minimize The Transfer Of Harmful Aquatic Organisms And Pathogens, For Submission To The 20PthP Assembly For Adoption.
There Has Been Increased Awareness In Recent Years Of The Environmental Damage Caused By The Introduction Of Unwanted Aquatic Organisms In Ballast Water, Used To Stabilize Vessels At Sea. Examples Of Introductions Of Non-Indigenous Organisms In New Locations Include The Introduction Of The European Zebra Mussel (TDreissena PolymorphaT) In The North American Great Lakes, Resulting In Expenses Of Billions Of Dollars For Pollution Control And Cleaning Of Fouled Underwater Structures And Waterpipes; And The Introduction Of The American Comb Jelly (TMnemiopsis LeidyiT) To The Black And Azov Seas, Causing The Near Extinction Of The Anchovy And Sprat Fisheries.
Human Health Has Also Been Badly Affected, With The Transportation Of The Bacterium Vibrio Cholerae (Cholera) To Latin American Coastal Water, Probably Through Discharges Of Ballast Water From Asia, And The Introduction Of The South-East Asian Dinoflagellates Of The Genera TGymnodiniumT And TAlexandriumT, Which Cause Paralytic Shellfish Poisoning, To Australian Waters.
The Draft Guidelines, Which Have Been Drawn Up By A Working Group On Ballast Water, Are Aimed At Minimizing The Risks Of Introducing Harmful Aquatic Organisms And Pathogens While Maintaining Ship Safety. Some States Have Already Introduced Mandatory Management Of Ballast Water To Prevent The Introduction Of Exotic Species.
Guidelines For Preventing The Introduction Of Unwanted Organisms And Pathogens From Ships’ Ballast Waters And Sediment Discharges Were Adopted By The Committee In 1991 And Subsequently As An Assembly Resolution A.774(18), But The Revised Version Incorporates Further Recommendations On Tackling The Problem, Including How To Lessen The Chances Of Taking On Board Harmful Organisms Along With Ballast Water.
The Recommendations Include Informing Local Agents And/Or Ships Of Areas And Situations Where Uptake Of Ballast Water Should Be Minimized, Such As Areas With Known Populations Of Harmful Pathogens Or Areas Near To Sewage Outlets. Ships Should Operate Precautionary Practices, Through Avoiding Loading Ballast Water In Very Shallow Water Or In Areas Where Propellers May Stir Up Sediment. Unnecessary Discharge Of Ballast Water Should Also Be Avoided.
Procedures For Dealing With Ballast Water Include Exchange Of Ballast Water At Sea And Discharge To Reception Facilities, While The Guidelines Note That In The Future Treatment Using Heat Or Ultraviolet Light Could Become Acceptable To Port States.
Imo’s Maritime Safety Committee (Msc) And The Committee Have Already Approved Guidance On Safety Aspects Relating To The Exchange Of Ballast Water At Sea, Which Outlines Procedures For Exchanging Ballast Water And Point Out Safety Issues Which Need To Be Considered, Such As Avoidance Of Over And Under Pressurization Of Ballast Tanks And The Need To Be Aware Of Weather Conditions.
The Committee Approved A Programme Of Work For The Ballast Water Working Group, Which Includes Developing Draft Regulations On Ballast Water Management To Be Adopted As An Annex To Marpol At A Conference Of Parties To The International Convention For The Prevention Of Pollution From Ships, 1973, As Modified By The Protocol Of 1978 (Marpol 73/78), The Main International Convention Dealing With The Prevention Of Pollution From Ships. The Conference Is Scheduled To Be Held In The Year 2000.

Bridge Equipment-G.P.S.
Space Segment:
·         Satellites Are To Be Operated In 6 Orbital Planes In Very High Orbits, Approximately 20,200 Kms Above The Earths Surface.
·         Four Satellites Are Located In Each Plane Having One Spare In Every Alternate Orbit. The Configuration Being 21+3 Satellites. The Orbital Planes Are Inclined At 55 Degs To The Equator.
·         The Orbital Period Of These Satellites Is Just Under 718 Minutes Resulting In The Satellites Passing Over The Same Ground Point Each Day, Excepting The Fact That They Are Four Minutes Earlier (Give Or Take 1.7 Secs).
·         The Orbit Design Was Developed To Guarantee That Atleast Four Satelites Are Alkways In View At Every Point On The Earths Surface 24 Hours A Day.
Ground Segment:
·         The Ground Or Control Segment Refers To The Ground Based Element Of A Gps System Which Manages The Performance Of The Satellites
·         This Is Through Orbital Tracking, Clock Monitoring And Therefore Fundamentally Is Responsible For The Daily Control Of The System.
·         The Control Segment Of The Navstar System Consists Of Three Main Types Of Operational Facilities.
·         The Master Control Station Situated At Colorado Springs Is Responsible For Overall Satellite Control, Navigation Performance Estimation And Ephemeris Production.
·         Four Further Sites At Hawaii, Ascension Islands, Diego Garcia And Kwajalein Alongside The Master Are Operated As Monitor Stations For Tracking The Satellites And Collecting Range Data To Produce Information For Ephemeris (Orbit) Modelling.
·         Uplink Antennas To Transmit Navigation Data And Commands To The Satellites Have Also Be Hoisted From Such Stations.
·         The Uplink Frequency Is Centered On 1783.74 Mhz, With Downlink Frequency Of 2227.5 Mhz.
User Segment:
·         The User Segment Mainly Consists Of The Gps Antenna And Receiver, Additional Features However Would Include A Differential Gps Antenna And Various Interfaces Into Systems.
·         From Noise To Signal: The First Task For The Gps Receiver Is To Get Enough Signals From The Satellite Transmissions Into The Receiver Itself.
·         It Is Usually Achieved With A Pre-Amplifier/Head Amplifier In The Antenna Unit To Boost The Signal Before Sending It Down The Cable.
·         Antennas Are Designad To Receive All Signals Within The Relevant Band.The Gps Signals Are Very Weak And Indistinguishable From The Background Noise At First And Second Glance.
·         These Signals Are Also Spread Over A 20 Mhz Band-Width Centered Around The L1 Frequency Of 1575.42 Mhz. This Has The Same Effect As Transmitting A Much More Powerful Signal And Also Allows Much More Information To Be Incorporated Into The Transmissions.
·         From Signal To Numbers: Most Signal Processing Tasks Are Now Undertaken In Micro-Processors, But To Allow This The Signal Must Be Converted From Analogue To Digital Form.
·         From Numbers To Code: The Gps Receiver Will Now Have At This Point The Ability To Sample The Substantially Altered Frequency Of The Satellites. The Primary Task Of The Receivers Is To Measure Ranges To The Satellites.This Is Achieved By Attempting To Identify The Code Transmissions Superimposed On To The Signals.
·         Each Satellite Transmits A Unique Code, Or Technique Known As Code Division Multiple Access. To Identify The Code The Receiver Has To Produce An Exact Replica Of The Satellite Code Sequence And To Mach The Two Together.
·         From Numbers To Phase: To Make Use Of This Code Information To Produce Ranges And Thus Position The Receiver, Also Needs Another Set Of Information, The Satellite Ephemeris.
·         The Ephemeris Being Modulated Over The Carrier Frequency And Needs Also To Be Extracted.
·         From Measurement To Position: Once The Receiver Has Produced The Necessary Information In Terms Of Measured Pseudo Range And Navigation Data, This Is Then Poassed To A Dedicated Microprocessor Dealing With The Position Computation And, Usually, The User Interface As Well.
The Pseudo- Range:
The Pseudo- Range Is A Measure Of Distance From The Receiver To The Satellite, Usually Expressed In Mts.
The Term Pseudo Is Used Because The Range Is Contaminated. For Time To Be Accurately Measured Between The Two Sites The Clocks Must Be Accurately Synchronised. The Clocks Between The Satellites Are Synchronised, So The Ranges Measured Between Them Would Actuallyu Be True Ranges. But The Receiver Clock Is Not Synchronised To The Satellites Which Gives An Error Which Can Be Resolved Mathematically, Hence The Term Pseudo-Range.
The Pseudo-Range Cannot Be Converted To A True Range Without Other Sets Of Information, Namely Ranges To Three Other Satellites And Accurate Knowledge Of All The Satellites Positions In Space ( And Time )
Computation Of Position:
The Ability To Measure Pseudo Range And Knowledge Of The Satellites Position At All Times, The Gps Receiver Now Has Enough Information To Calculate A Position.
For Every Computation Of Position There Are, Then Four Unknowns Called X,Y,Z And T (For Time). But By This Point The Receiver Has Also Managed To Acquire A Whole Series Of Knowns Namely, Pseudo Ranges To The Satellites And The Position Of Those Satellites. As Long As The Receiver Can Measure As Many Ranges To The Satellites As There Are Unknowns Then Position Can Be Calculated Quite Simply Through A Series Of Four Simultaneous Equations.
This Is A Mathematical Technique That Uses A Combination Of Known Quantities To Calculate A Combination Of Unknown Quantities, But It Does Require Symmetry In Its Equation Forms- Basically The Same Number Or More Knowns To Unknowns.
The Dilution Of Precision:
This Is One Of The Primary Quality Control Indicators Available To The User Of The Gps Receiver. It Indicates The Geometrical Relationship Of The Satellites.
The Dilution Of Precision Was The Mechanism Userd By The Gps System Planners To Identify The Best Orbit Geometry Of The Satellites To Provide The Best User Geometries.
On Its Own The Dop Figure Is Only A Qualitative Figure With The Prescribed Numbers Not Being Of Any Specific Units. The Most Complete Dop Is The Geometric Dilution Of Precision (Gdop). This Is The Factor Used To Design The Orbital Arrangement Of The Satellites. Gdop Brings Together The Four Unknowns Of The System.
The Most Frequently Used Dop’s Are Pdop ( Position Dilution Of Precision) And Hdop ( Horizontal Dilution Of Precision). Pdop Is Used By Those Interested In Three Dimentional Positioning (Lat/Long/Ht). Hdop Is For Two- Dimensional Positioning. For Most Purposes Hdop Is Used By The Marine Community.
Dop Figures Are Actually Used By A Navigator In The Following Way. If A Composite Pseudo-Range Measurement Error Of 10 Mts. (95% Probability) Is Assumed For The System, Then By Multiplying This Figure By The Relevent Dop Value, Eg. 3.0, Gives An Overall Position Accuracy Of 30 Mts. Dop Figures Are Therefore Only Relative Numbers, With Smaller Dop’s Giving Better Accuracies.
The Final Constellation Is Designed To Guarantee Pdop Figures Of Better Than 12.0 All Over The Earth’s Surface, Though Figures Of Better Than 7.0 Are To Be Generally Expected. For Marine Applications Hdop Figures Are More Useful & The Design Figure Of 3.0 Is To Be Expected For The Majority Of Coverage.
Errors Of The System.
1.    Gdop - If The Configuration Of The Available Satellites Is Not Suitable, Accuracy Of The Fix Is Affected.
2.    Ionospheric & Tropospheric Delays Of Signals - While Ultra High Frequencies Are Used For Transmission, Yet The Ionosphere & Troposphere Refract The Signals Causing Delays Which Lead To Inaccuracy Of Positions. These Errors Can Be Reasonably Predicted & Are Fed Into A Mathematical Model Built Into The Software Of The Receiver.
3.    Satellite Clock Error - Any Errors In The Clocks On Board The Satellites Will Lead To Errors In Time Measurement.
4.    User Clock Error - Same As Above. This Is Eliminated By Using An Extra Satellite Equation
5.    Deviation Of Satellites From Their Predicted Orbits - Since The Position Of The Satellites Needs To Be Known Very Accurately, It Is Obvious That If The Satellite Deviates From Its Orbit, For Any Reason, Then Inaccuracy In Fixes Will Result.
6.    Receiver Errors - These Are Small & Are Caused Due To Internal Noise, Computational Errors, Etc.

Users.
The Satellite Geometry Is Presented To The User By A Factor Known As The Dilution Of Precision. These Figures Are Used To Assess The Potential Positioning Quality Of A Certain Satellite Constellation And To Help Provide Realistic Quality Control Information. The Procedure Used To Define These Values Is Quite Complicated, But It Relates The Difference In Three Dimentions Of The User To All The Concidered Satellites In A Geometrical Sense.
The Resultant Dop Figure Then Suggests The Amplification Of Pseudo-Range Measurement Error Into User Positioning Error. Differen Dop’s Are Used Depending On The Type Of Position Calculated. Hdop For A Two Dimentional Fix And Pdop For A Three Dimentional Fix.
The Dop Figures Are Used By The Navigator In The Following Way. If A Composite Pseudo-Range Measurement Error Of 10 Metres (95% Probablity) Is Assumed For The System, Then Multiplying This Figure By The Relevant Dop Value, Eg. 3.0, Gives An Overall Positioning Accuracy Of Thirty Metres. Dop Figures Are Therefore Only Relative Numbers, With Smaller Dop’s Giving Better Accuracy. The Probablity Figures Detailed In The Circular Brackets Are Indications Of The Confidence In The Position Accuracy.

Bridge Equipment - Logs
Electromagnetic Log:
In A Magnetic Field Created By A Solenoid, The Magnetic Flux Lines Extend Out In The Water. Salt Water Being A Conductor Flowing Past The Solenoid Creates An Emf. This Is Picked Up By A Sensor & A Pre-Calibrated Voltmetre.
The Voltage Induced Is Proportional To The Speed Of The Water.
Doppler Effect:
The Doppler Frequency Shift Is The Difference Between The Received Frequency Which Can Be Measured & The Transmitted Frequency Which Is Known.
·         There Are 2 Types Of Logs;
1.    Continuous Wave (Cw) &
2.    Pulse Type.
The Pulse Type Is Better Than The Cw. Type Because There Is A Signal Leakage From The Transmitter To The Reeciver Which Interferes With The Received Signal (Feedback).
·         It Uses A Higher Frequency Than The Echo Sounder As The Smaller Wavelength Makes A Concentrated Beam Possible Hence, Less Loss Of Energy To Water, Stronger Echoes & Smaller Area Of Transducer Required. Also Diffused Reflection Is Acquired By The High Frequency Which Is Neccesary Because Of Oblique Incidence Of The Transmitted Pulse.
