PERFORMANCE STANDARDS FOR INTEGRATED NAVIGATION SYSTEMS (INS)

 

1. Purpose of integrated navigation systems

 

1.1 The purpose of integrated navigation systems (INS) is to enhance the safety of navigation by providing integrated and augmented functions to avoid geographic, traffic and environmental hazards.

 

1.2 By combining and integrating functions and information the INS provides "added value" for the operator to plan, monitor and/or control safety of navigation and progress of the ship.

 

1.3 Integrity monitoring is an intrinsic function of the INS. The INS supports safety of navigation by evaluating inputs from several sources, combining them to provide information giving timely alerts of dangerous situations and system failures and degradation of integrity of this information.

 

1.4 The INS presents correct, timely, and unambiguous information to the users and provides subsystems and subsequent functions within the INS and other connected equipment with this information.

 

1.5 The INS supports mode and situation awareness.

 

1.6 The INS aims to ensure that, by taking human factors into consideration; the workload is kept within the capacity of the operator in order to enhance safe and expeditious navigation and to complement the mariner's capabilities, while at the same time to compensate for their limitations.

 

1.7 The INS aims to be demonstrably suitable for the user and the given task in a particular context of use.

 

1.8 The purpose of the alert management is specified in module C.

 

2. Scope

 

2.1 Navigational tasks

 

2.1.1 An INS comprises navigational tasks such as "Route planning", "Route monitoring", "Collision avoidance", "Navigation control data", "Navigation status and data display" and "Alert management", including the respective sources, data and displays which are integrated into one navigation system. These tasks are described in paragraph 7.

 

2.1.2 An INS is defined as such if work stations provide multifunctional displays integrating at least the following navigational tasks/functions:

 

- "Route monitoring"

 

- "Collision avoidance"

 

and may provide manual and/or automatic navigation control functions.

 

2.1.3 Other mandatory tasks

 

2.1.3.1 An alert management is a part of the INS. The scope and the requirements of the alert management are specified in module C.

 

2.1.3.2 The presentation of navigation control data for manual control as specified in paragraph 7.5.2 of these performance standards is part of the INS.

 

2.1.4 Other navigational tasks/functions may also be integrated in the INS.

 

2.2 Task stations

 

2.2.1 The tasks are allocated to, and operated by the operator on, a defined set of multi-functional "task stations".

 

2.2.2 The scope of an INS may differ dependent on the number and kind of tasks integrated.

 

2.2.3 Configuration, use, operation and display of the INS is situation-dependent on:

 

- shift underway, at anchor, and moored,

 

- manual and automatic navigation control in different waters,

 

- planned routine navigation and special manoeuvres.

 

3. Application of these performance standards

 

3.1 Purpose of these standards

 

3.1.1 The purpose of these performance standards is to support the proper and safe integration of navigational functions and information.

 

3.1.2 The purpose is in particular:

 

- to allow the installation and use of an INS instead of stand-alone navigational equipment onboard ships; and

 

- to promote safe procedures for the integration process;

 

both for

 

- comprehensive integration; and

 

- partial integration,

 

of navigational functions, data and equipment.

 

3.1.3 These standards supplement for INS functional requirements of the individual Performance Standards adopted by the Organization.

 

3.2 Application to tasks

 

3.2.1 These performance standards are applicable to systems where functions/equipment of at least the navigational tasks mentioned in paragraph 2.1.2 are combined.

 

3.2.2 If further tasks are integrated, the requirements of these standards should apply to all additional functions implemented in the INS.

 

3.3 Modules of these standards

 

3.3.1 These performance standards are based on a modular concept which should provide for individual configurations and for extensions, if required.

 

3.3.2 These standards contain four modules:

 

- Module A for the requirements for the integration of navigational information,

 

- Module B for the operational/functional requirements for INS based on a task-related structure,

 

- Module C for the requirements of the Alert management, and

 

- Module D for the Documentation requirements.

 

3.4 Application of modules These performance standards are applicable to all INS as follows:

 

3.4.1 Modules A, C, D and paragraphs 6, 8 to 13 of module B are applicable for any INS.

 

3.4.2 Additionally, for each task integrated into the INS, the INS should fulfil both:

 

- the requirements of the respective tasks as specified in paragraph 7 of module B and

 

- the relevant modules of performance standards for stand-alone equipment as specified in Table 1.

 

Table 1

 

 

3.5 Acceptance of INS as navigational equipment

 

3.5.1 These standards may allow for accepting INS to substitute for some carriage requirements of navigational equipment as equivalent to other means under SOLAS regulation V/19. In this case, the INS should comply with:

 

- these performance standards; and

 

- for the relevant tasks of these performance standards, with the applicable modules of the equipment performance standards as specified in Table 2.

 

Table 2

 

 

3.6 The application of the alert management is specified in module C.

 

3.7 Other relevant standards

 

3.7.1 The workstation design, layout and arrangement is not addressed in this performance standards, but in MSC/Circ.982.

 

4. Definitions

 

For the purpose of these standards the definitions in Appendix 1 apply.

 

Module A – Integration of Information

 

5. Requirements for integration of navigational information

 

5.1 Interfacing and data exchange

 

5.1.1 An INS should combine, process and evaluate data from connected sensors and sources.

 

5.1.2 The availability, validity and integrity of data exchange within the INS and from connected sensors and sources should be monitored.

 

5.1.3 A failure of data exchange should not affect any independent functionality.

 

5.1.4 Interfacing to, from, and within the INS should comply with international standards for data exchange and interfacing as appropriate.

 

5.1.5 The interface(s) should comply with the interface requirements of the alert management as described in Module C of these performance standards.

 

5.2 Accuracy

 

5.2.1 INS data should comply with the accuracy and resolution required by applicable performance standards of the Organization.

 

5.3 Validity, plausibility, latency

 

5.3.1 Validity

 

5.3.1.1 Data failing validity checks should not be used by the INS for functions dependent on these data, unless for cases where the relevant performance standards specifically allow use of invalid data. There should be no side effects for functions not depending on this data.

 

5.3.1.2 When data used by the INS for a function becomes invalid, or unavailable, a warning should be given. When data not actually in use by the INS becomes invalid, or unavailable, a this should be indicated at least as a caution.

 

5.3.2 Plausibility

 

5.3.2.1 Received or derived data that is used or distributed by the INS should be checked for plausible magnitudes of values.

 

5.3.2.2 Data which has failed the plausibility checks should not be used by the INS and should not affect functions not dependent on these data.

 

5.3.3 Latency

 

5.3.3.1 Data latency (timeliness and repetition rate of data) within the INS should not degrade the functionality specified in the relevant performance standards.

 

5.4 Consistent common reference system (CCRS)

 

5.4.1 Consistency of data

 

5.4.1.1 The INS should ensure that the different types of information are distributed to the relevant parts of the system, applying a "consistent common reference system" for all types of information.

 

5.4.1.2 Details of the source and the method of processing of such data should be provided for further use within INS.

 

5.4.1.3 The CCRS should ensure that all parts of the INS are provided with the same type of data from the same source.

 

5.4.2 Consistent common reference point

 

5.4.2.1 The INS should use a single consistent common reference point for all spatially related information. For consistency of measured ranges and bearings, the recommended reference location should be the conning position. Alternative reference locations may be used where clearly indicated or distinctively obvious. The selection of an alternative reference point should not affect the integrity monitoring process.

 

5.4.3 Consistency of thresholds

 

5.4.3.1 The INS should support the consistency of thresholds for monitoring and alert functions.

 

5.4.3.2 The INS should ensure by automatic means that consistent thresholds are used by different parts of an INS, where practicable.

 

5.4.3.3 A caution may be given when thresholds entered by the bridge team differ from thresholds set in other parts of the INS.

 

5.5 Integrity monitoring

 

5.5.1 The integrity of data should be monitored and verified automatically before being used, or displayed.

 

5.5.2 The integrity of information should be verified by comparison of the data derived independently from at least two sensors and/or sources, if available.

 

5.5.3 The INS should provide manual or automatic means to select the most accurate method of integrity monitoring from the available sensors and/or sources.

 

5.5.4 A clear indication of the sensors and sources of data selected for integrity monitoring should be provided.

 

5.5.5 The INS should provide a warning, if integrity verification is not possible or failed.

 

5.5.6 Data which fails the integrity monitoring function or data where integrity monitoring is not possible should not be used for automatic control systems/functions.

 

5.6 Marking of data

 

5.6.1 The data should be marked with the source and the results of validity, plausibility checks and integrity monitoring to enable subsequent functions to decide whether their input data complies with their requirements or not.

 

5.7 Selection of sensors and sources

 

5.7.1 INS should provide two user selectable sensor/source selection modes when multiple sensors/sources are available; manual sensor/source selection mode and automatic sensor/source selection mode.

 

5.7.2 In manual sensor/source selection mode it should be possible to select individual sensors/ sources for use in the INS. In case a more suitable sensor/source is available this should be indicated.

 

5.7.3 In automatic sensor/source selection mode, the most suitable sensors/sources available should be automatically selected for use in the INS. It should further be possible to manually exclude individual sensors/sources from being automatically selected.

 

Module B – Task related requirements for Integrated Navigation Systems

 

6. Operational requirements

 

6.1 The design of the INS should ease the workload of the bridge team and pilot in safely and effectively carrying out the navigation functions incorporated therein.

 

6.2 The integration should provide all functions, depending of the task for which the INS is used and configured, to facilitate the tasks to be performed by the bridge team and pilot in safely navigating the ship.

 

6.3 Each part of the INS should comply with all applicable requirements adopted by the Organization, including the requirements of these performance standards.

 

6.4 When functions of equipment connected to the INS provide facilities in addition to these performance standards, the operation and, as far as is reasonably practicable, the malfunction of such additional facilities should not degrade the performance of the INS below the requirements of these standards.

 

6.5 The integration of functions of individual equipment into the INS should not degrade the performance below the requirements specified for the individual equipment by the Organization.

 

6.6 Alerts should be generated and presented according to Module C.
