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.
