An ECDIS is an electronic system that can display navigational charts and position information to serve as an alternative to paper charts. It integrates data from GPS, radar, and AIS to determine a vessel's position in relation to land, hazards, and navigation aids. The IMO requires all ships to carry electronic charts and ECDIS to meet chart carriage requirements. When planning a passage using ECDIS, the navigator must ensure the vessel has up-to-date chart licenses, enter vessel parameters, set the safety contour and domain, and create a route by placing waypoints while checking for hazards. ECDIS is then used during the voyage to monitor position and trigger alarms if safety parameters are exceeded.

This document provides an overview of differential GPS (DGPS) and its history. It explains that DGPS uses fixed, ground-based reference stations to broadcast corrections to improve GPS accuracy from 15 meters to about 10 cm. Selective availability was introduced by the US military to degrade civilian GPS but was turned off in 2000. DGPS was developed as a solution, broadcasting corrections to offset errors and allow 5 meter accuracy, meeting most civilian needs. It has expanded to cover many waterways through systems like the US Coast Guard's National DGPS.
The document outlines 17 performance standards that GPS receiver equipment installed on ships must meet in order to be compliant. The standards require the equipment to:
1) Be capable of receiving and processing GPS signals to provide position, latitude and longitude, in the WGS-84 coordinate system and UTC time within specified accuracies and update rates.
2) Have static and dynamic position accuracy of 100m or less depending on whether differential GPS corrections are applied.
3) Generate and output position, course, speed, and time data at least once per second and interface with other navigation equipment.
4) Provide warnings if performance standards for position dilution or update rates are not met.
Optimizing precision final approach through gbasIrfan iftekhar
Ground-based augmentation systems (GBAS) provide localized precision GPS corrections to aircraft, enabling precision approaches. GBAS has benefits over instrument landing systems like supporting more runways with one system. GBAS also allows for flexible siting, steadier guidance, and less frequent inspections. While GBAS can increase efficiency and capacity, limitations remain such as the need for aircraft and ground infrastructure to support its full capabilities. Airports are working to certify GBAS for low-visibility operations and eventually replace ILS.

Trajectory estimation studies for long coasting phase of mars missioneSAT Journals
Abstract At Sriharikota range, configuration of down range tracking network, Real-time tracking and trajectory estimation play a critical role during a satellite launch for flight safety as well as mission monitoring. Criticality is more when the mission parameters vary during the launch window to meet the mission requirements. PSLV-C25, the 320 T XL version is intended to inject the 1337.24 Kg MARS Orbiter into 250 Km * 23500 Km * 19.2 deg Sub-GTO orbit. MARS Orbiter Mission [MOM] is the first Indian interplanetary mission to orbit a spacecraft around MARS in an elliptical orbit of 360km * 80000 km. This paper deals with the trajectory estimation and prediction methodologies studied and established at Sriharikota Range for this launch. The major challenge in the Mars orbiter mission is to configure the Down range network of Telemetry stations in view of large variation in the Argument of Perigee (AOP) requirement ranging from 2760 to 2890 during injection over the period of launch window. Requisite AOP facilitates transit of the Spacecraft from Earth to Mars using minimum energy Hohmann transfer. The change in the requirement of AOP each day in turn demanded a new trajectory with its characteristic changes in long coasting duration, fourth stage ignition time and subsequent MARS Orbiter injection time into sub-GTO. It is mandatory to capture the Telemetry data during those critical events to assess the success of the mission. The flight duration was around 3000s and the coasting duration was 1600s before the ignition of the PS4 stage. Study of configuration of mobile Telemetry stations on Ship-borne terminals is carried out to cater to visibility requirements of critical events such as fourth stage ignition time and subsequent MARS Orbiter injection. State vector accuracy studies are carried out for the Ship-borne radar data of the vehicle during long coasting using Linear Kalman filter. Also a trajectory extrapolation algorithm is designed and studied to provide extrapolated trajectory during the long coasting period after 3rd stage burn out which in turn is used to compute and display trajectory parameters to mission executives and provide antenna-pointing information to the ship-borne terminals. This paper presents the trajectory estimation methodology proposed, extrapolation techniques adopted and accuracies achieved for the long coast duration. Keywords: Mars Orbiter Mission (MOM), Flight Safety, Trajectory estimation, Network simulations, Argument of Perigee (AOP).
Design & application of cdo for ahmedabad airport within ahmedabad tmaARVIND KUMAR SINGH
ICAO has emphasized on aviation safety, air navigation capacity and efficient environmental protection by strategic objective. ICAO also focused on the development and implementation on PBN, CDO and CCO for sustainable growth of aviation. Global Air Navigation Plan (2013-2028) provides methodology for integrated aviation planning and increased importance of collaborations and partnership among stakeholders. GANP outlined the implementation issues involving the PBN all over the world. In line with ICAO objective, this focuses on CDO procedure at Ahmedabad airport.
Trial CDO has been implemented but no formal procedure for airlines operator has yet been promulgated at various Indian airports including Ahmedabad Airport. Area and Approach are physically located at same place and trained controllers provide these services on rotation basis at Ahmedabad airport. Air Traffic Services provided with surveillance tools. STARs and SIDs were introduced in year 2008 at Ahmedabad Airport. Ahmedabad Airport has medium density traffic of aircraft movement, average 150 schedule aircraft movement per day and approx 75 scheduled arrivals per day. Due to non availability of published procedure limited Continuous Descent Operations are being performed by the arrivals, at Ahmedabad Airport.
This emphasises on analysis of traffic pattern on arrival routes for possible implementation of CDO is existing arrival procedures and study of existing CDO procedure, analysis of cost benefit, fuel efficiency and carbon emission for Ahmedabad airport.
Design & Application of Continuous Descent Operation (CDO) procedure in Ahmedabad TMA for Ahmedabad Airport will provide more efficient airspace & arrival routes, reduction in pilot –controller work load, cost saving to airlines operators and environmental benefits through reduced fuel burn.
With good CDO procedure, initially minimum 65% of arrivals are expected to perform CDO at Ahmedabad leading to saving of cost of operations and carbon emission, in addition to brand and image building of AAI as ANSP at Ahmedabad. The experience gained will also help AAI extend such procedure to other medium to light density traffic airports and subsequently all airports in line with ICAO Guidelines and requirement.

A Review on Longitudinal Control Law Design for a Small Fixed-Wing UAVIRJET Journal
This document reviews various techniques for designing longitudinal control laws for small fixed-wing unmanned aerial vehicles (UAVs). It discusses techniques such as integral sliding mode control, linear quadratic regulator (LQR), Apriltags recognition algorithm with PID control, observer Kalman identification with PID control, root locus method, nonlinear model simulation, and multi-model techniques. These techniques have been applied to problems such as longitudinal guidance, stability augmentation, autonomous landing, and modeling fixed-wing UAV dynamics. The document analyzes the effectiveness and robustness of different proposed control schemes through simulations and comparisons of various techniques.
The document discusses ACARS, an aircraft communications system introduced in 1978 that uses VHF and satellite datalinks to transmit messages between aircraft and ground stations. It allows transmission of operational data like flight plans, maintenance issues, and position reports. While ACARS was a major improvement over prior voice-only systems, its 2400 baud rate is now too slow as data needs grow. Congestion is increasing on the VHF frequencies it uses. The solution is a transition over the next 20 years to newer protocols like ATN and the Internet Protocol that can better handle rising traffic demands.
The document discusses preparations for the mandatory carriage of ECDIS on vessels over 3,000 GT. It provides an overview of the implementation schedule, which requires all vessels over 10,000 GT to have ECDIS installed by 2018. Vessels must have one type-approved ECDIS and suitable backup arrangements, such as a second ECDIS or paper charts. The document also reviews the benefits of ECDIS, such as improved voyage planning and safety, easier chart management, and logging of navigation data. It provides information on electronic chart types, system configurations including single or dual ECDIS, and possibilities for integrating ECDIS with other bridge systems.
This document proposes using existing vessel data and minimal additional investments to generate accurate mathematical models (MM) and computerized fluid dynamics (CFD) simulations to optimize fuel efficiency for ocean-going vessels. It involves collecting data on vessel characteristics and weather conditions to model friction and resistance. The models would calculate the most fuel-efficient routes, speeds, and draft/trim combinations. They could help masters address unusual phenomena and reduce challenges like operating at non-optimal drafts/trims. There is potential for commercial applications to various vessel types and alternative fuels.

Aviation - True North - Time to Change
1. NAV CANADA
MAGNETIC VS
TRUE NORTH
Vision to 2030
Captain Anthony MacKay
Director Flight Operations
26/09/2017
2. NAV CANADA
› All of the aircraft, air traffic and IFR
procedure design systems are built to
function in TRUE
› Tables are then devised to translate that
data to magnetic for the user
• Not all tables function exactly the same
• Older tables in systems may not be updated
• Translations may not be matched
› Much effort has been expended to manage
MAG VAR
› The questions should be:
• Why do we still navigate by reference to
Magnetic North? Why do we not switch to
TRUE?
THE ISSUE
Which way is North?
3. NAV CANADA
› Canada has always operated with airspace
referenced to True and Magnetic
• Northern Domestic Airspace = True
• Southern Domestic Airspace = Magnetic
› In NDA all ILS, VOR and NDBs at set to
TRUE with 0 degrees declination
› All airways are reference to True
› All terminal procedures are referenced to
True
• ILS, LOC, NDB, TACAN
• RNAV – LNAV, LNAV/VNAV, RNP AR, LPV
BACKGROUND
Canada’s Experience
4. NAV CANADA
› 21 Aerodromes with IAPs in the Area of Compass Unreliability
› 18 Aerodromes with IAPs outside the Area of Compass Unreliability in NDA still referenced to True
BACKGROUND
What is in NDA?
21 A/Ds in the
Area of Compass
Unreliability
5. NAV CANADA
› In SDA all procedures are referenced to
Magnetic. Mag Var is maintained:
• ILS, VOR & NDB maintained within ±2°
› CAT II/III ILS maintained within ±1°
• Airways/routes maintained within ±2°
• IAPs maintained within ±2°
• Surveillance RADAR, ADSB, MLAT
maintained IAW Mag Var tables reference
date and time.
› Hence we have the same issues in SDA as
other ANSPs
BACKGROUND
Canada’s Experience
6. NAV CANADA
› In the analogue world it was not as important. In the digital world it is.
• Magnetic variation/station declination doesn’t have to be right but it must match across databases
› Anchorage ILS CAT II/III issue - aircraft unstable in heading during approach
› Vancouver and St. John’s CAT II/III issue same as Anchorage
› Autoland aircraft moving off the centreline when the aircraft enters the flare
• Leg disconnects on non TF/RF legs
• SVS and EVS images superposed on the real world?
› Runways not aligned
› Sources of mag var on a modern aircraft and its use (at times they don’t perfectly match)
• IRUs – internal mag var tables
• Flight Management systems
› Base mag/var tables; VHF NAV aid reference mag var; Airport reference mag var; Procedure design mag var
• SVS systems, displays and charted mag var (static)
BACKGROUND
The Issue with Magnetic Variation
7. NAV CANADA
› CYEV VOR DME RWY 24.
• YEV dec = 23°E
• CYEV var = 25°E
• FMS Epoch = 26°E
• Design mag var = 24.92°E
› Difference in values cause
leg disconnects on the
approach and track change
251° to 248° at TURKIS. A
second track change
occurs in the GA for the
hold
BACKGROUND
The Issue with Magnetic Variation – An example
› This happens to a greater or lesser
degree on all approaches and at all
airports where mag var is in play.
8. NAV CANADA
› Modern aircraft, surveillance systems, IAPs are all designed to function in true
• Everything under the hood in a modern aircraft does the ‘math’ in True and then converts the information
to magnetic for the pilot
• All of Canada’s surveillance systems operate in True and then add in magnetic variation to display to the
controller
• All IAPs in Canada are designed in True and then have magnetic variation/declination added to the design
file for charting and nav databases
› This introduces cost and potential error into the system
› Updating aircraft FMS and IRU mag var tables every five years
• One carrier reported (2016) a cost of $21m for 200 aircraft; another reported $1.2m for one fleet type of 32
aircraft. Costs are aircraft age dependent (field loadable or repair facility). Our DH8-100 was $500k.
› Updating IAPs, Enroute Charts (VFR & IFR) and rotating VORs
• For Canada ~$800k per year
› Updating Airport data, runway numbering, signage
• Est. $10,000 per hold line (Paint, Signs, Data) (L) CYYZ ~ $1.1m, (M)CYHZ ~ $150k, (S)CYDF ~ $40k
CHANGING TO TRUE
The case for change
9. NAV CANADA
› Pick a date way out in the future (2030 – 2035)
• IRU equipped aircraft could go to True with MAG/TRUE switch
• New AHRUs (Fibre Optic Gyro (FOG), Micro Electromechanical Systems (MEMS) technologies do not
need flux valves for magnetic sense)
› Honeywell Super AH-2100; Northrop Grumman LCR-100, 110, 200, 300; Collins AHS-4000
› Light aircraft GNSS equipped (GNSS functions in True)
• VFR aircraft can still use a magnetic compass and convert to True
› Set runway heading prior to take-off
› Circular slide rule with E&W variation
› GPS/NDB Method
• Direct to a NDB, note bearing, rotate heading for ‘bearing to’ on ADF needle
CHANGING TO TRUE
When and how?
10. NAV CANADA
CHANGING TO TRUE
States (ANSPs) Affected
› Yellow = ±4° variation
› Magenta = ±10° variation
› Reducing impact of the
change
• Procedures within ±4°
variation could be left as is
until the next review date
• Airports within the ±10°
could update numbering,
signage and data at their
convenience.
11. NAV CANADA
› Beginning with the users – Can IATA and its carriers validate the costs for Epoch updates and
support the change with representation to the ICAO FLTOPSP
› ICAO – at the 12th Air Navigation Conference, Canada presented WP/147 of which the following
was included in final report – Section 6.4.25 which states:
• “The meeting was informed that currently a significant effort is expended to update aeronautical information with changing magnetic variation
(MAGVAR). Modern avionics carry out navigation calculations with reference to true north, and then convert the information for pilot displays
to Magnetic (by applying a magnetic variation based on a magnetic model), or True heading or true Track, depending on aircraft capability. It
was suggested that having all operations referenced to true north would enhance the overall safety floor and save considerable effort in
maintaining MAGVAR tables. The meeting noted the information and concluded that any States interested in the matter could conduct further
studies of the technical and operational impact of the proposal, and of the expected costs and benefits to all aviation stakeholders. Magnetic
variation has always posed a problem for the design and operation of instrument procedures from the enroute through to terminal and
approach phases of flight. While Heading Reference System use flux valves and a magnetic sense for directional guidance, Inertial
Reference Units operate in TRUE and use a magnetic variation table to look up local values and then present magnetic data to the aircraft
and pilot.”
Reference: AN-Conf/12-WP/162
CHANGING TO TRUE
Building support
12. NAV CANADA
› Working with the International Association Of Institutes Of Navigation (IAIN) to gain
worldwide exposure
• An IAIN member is briefing the International Symposium on Precision Approach and Performance Based
Navigation in Munich November 2017
› We will consult with other ANSPs through CANSO based on support from the operator
community.
› Regional and light aircraft associations
• Assist them in seeing the benefits of changing to AHRS units that do not rely on flux valves and magnetic
alignment
› Educate industry groups; IATA members, ICAO, CANSO
› How do we raise this topic with the FAA?
CHANGING TO TRUE
Overcoming years of magnetic pull…
13. NAV CANADA
› VFR users technically still use track/drift lines on VNCs although most use some form of GPS
and electronic moving map
› IFR GA aircraft would need to have a procedure to deal with East/West variation between the
heading observation from the wet compass to setting the HSI
• Most procedures are now track based with the exception of vectors, NDB IAPs and heading based legs in
vector SIDs and downwind legs on STARs

14. NAV CANADA
› The challenge is most current aircraft use a magnetic sense to feed the AHRU
• One regional airline in Canada has been searching for options to do this based on AHRS obsolescence
(AH-600) and repair costs.
• Low wing aircraft (CRJs) have had issues with flux valves and interference from rebar in runways (KORD)
where they have to depart in free gyro mode.
› The addition of an IRUs to replace current AHRUs would also be the foundation for RNP
operations
• Assist them in seeing the benefits of changing to AHRUs that do not rely on flux valves and magnetic
alignment, lower life cycle costs, additional operational capability
› With an implementation date out to 2030-2035 the regional carriers should be able to adapt
• Lobby manufacturers to switch to non-magnetic AHRUs in new aircraft or new certifications
THREE USER SEGMENTS
Regional Aircraft
15. NAV CANADA
› Large aircraft generally have Inertial Reference Units on board today
› Just need the ability to switch from MAG to TRUE to bypass the mag var values
› Some operators indicate they operate in Oceanic Airspace in True
› Operators on Polar Routes operate in the Keyhole in True but not necessarily in Canadian NDA
in True
› Savings to be had for IATA carriers with the elimination of 5 years Epoch updates

› Safety Impact - Positive.
• The charts will match the FMS database, procedure design file, ATS systems. Everyone will have the
same data instead of dealing with differences as described in this FAA INFO LETTER 12009 (06/26/12)
excerpt
› It is important to understand, however, that RNAV systems, (with the exception of VOR/DME RNAV
equipment) navigate by reference to true north and display magnetic course only for pilot reference. As such,
a properly functioning RNAV system, containing a current and accurate navigational database, should
still fly the correct ground track for any loaded instrument procedure, despite any differences in magnetic
course that may be attributed to magnetic variation application.

True North Mode
Worldwide ±1°
17. NAV CANADA
› Financial Impact – Positive for aircraft, airports and ANSPs in the long term.
• Airports and ANSPs will have a ONE TIME charge to make the change to True that can be managed.
Data and signage will not need to change for mag var again.
• Aircraft operators with IRUs would need to enable the MAG/TRUE functions if not currently active. Aircraft
operators that need a slaved AHRS would have a one time charge. Light aircraft without a slaved system
would use a cost neutral procedural method.
• No more working groups to look at Magnetic Variation issues – PARC, RTCA
• Simplification of avionics design in the long term
ICAO INTERESTS
Considerations
18. NAV CANADA
› Security Impact - Neutral
› Environmental Impact – Positive
• Less energy of all types expended for mag var updates
• GHG reduced to 0 for VOR Rotations and airway flight checks after mag var changes
› Efficiency Impact – Positive
• No loss of services due to procedures notam’d out of service for mag var issues
• No loss of CAT II/III services due to mar var differences
• ANSPs can focus on new procedure development instead of running the tread mill of corrections for mag
var on current procedures (reduced procedure maintenance)
› Expected Implementation Time – Positive
• 2030 to 2035 to allow ANSPs to enact a plan and for aircraft operators with slaved gyro’s to replace
obsolete units with non-magnetic north seeking units.
ICAO INTERESTS
Considerations
19. NAV CANADA
› Flight Test ‘True’ database
• Jeppesen took all the data (flight test database) for airports, airways, IAPs and changed all the magnetic
variation to ’00’ for a flight test area in eastern Canada
• NAV CANADA flight test aircraft will fly a mixed flight plan of V/J airways, T/Q routes, NDB, VOR and
RNAV procedures in True Mode to see if switching the database would be that easy.
• Reasoning – KRFD has a magnetic variation value of 0 (= True). All of KFRDs associated procedures
work within a MAG system.
