Chapter 1: Introduction
1.1 System Description
Intended Use
The NAVIGAT 100 is a digital gyrocompass standalone system for the
maritime navigation of vessels and must be operated only from appro-
priately trained and educated personnel familiar with all mandatory
safety and operating procedures.
The NAVIGAT 100 provides North-speed error corrected true heading
data as well as rate of turn (ROT) data for the navigation of maritime
vessels.
The NAVIGAT 100 is not designed to operate in a dual gyrocompass con-
figuration or as part of the Sperry Marine CompassNet (CN) Heading
Management System (HMS).
Not Intended Use
The NAVIGAT 100 and/or the provided true heading and ROT data of the
NAVIGAT 100 are not allowed to be used for the navigation of inland
water vessels and river boats.
Although the NAVIGAT 100 is a highly accurate system for providing
true heading and ROT data, operators must not rely on it solely as the
only heading source. The plausibility of the NAVIGAT 100 heading and
ROT data and the speed and position input data (as secondary data)
must always be confirmed against all other available aids to navigation.
Since the NAVIGAT 100 system can additionally be used for displaying
secondary navigation data (speed and position input data) generated
from other connected devices, the operator must not take displayed sec-
ondary data for granted and is obliged to confirm the validity of second-
ary data independently.
When navigating in polar waters (according to E190E IMO Guidelines
definition), the heading information of the gyrocompass may become
unstable/unreliable, due to physical principles, resulting in possible
deviation. For safe steering of the vessel in polar waters, the heading
information of the gyrocompass may therefore not be used and heading
information of a GNSS (Global Navigation Satellite System) compass be
preferred instead.
