“CNS-2011” Simulator may be used for training cadets of higher and secondary educational institutions studying the “Nautical astronomy” discipline as well as small craft navigators course students.

Normative base

“CNS-2011” Celestial Navigation Simulator is developed in strict compliance with STCW Convention requirements taking into account The Manila amendments (Section B-II/1 "Training in celestial navigation"), coming into effect on January, 1, 2012.

Purpose

Simulator is intended for drilling celestial altitude measurements in real time mode, position-finding and heading indication system adjustment reckoning with the help of celestial instruments and aids.

Configuration

Software of the simulator is intended for operation in local computer network and consists of Instructor WorkPlace (IWP) and Student WorkPlaces (WPS).

Instructor WorkPlace functions

Job stacking, including:

Task assignment;
Area of navigation finding;
Observer’s height of eye;
Date and time of observation;
Sextant and gyro correction for index error;
Limit of time for task execution.
Target vessels position;
Atmospheric conditions;
Instruments’ corrections superset.

Task issuing to Student WorkPlace.

Auto assessment of student’s measurements in accordance with criteria set by instructor.

Simulator training results report generation.

Student WorkPlace functions

Student WorkPlace simulates:

celestial sphere adequate to chosen ship's position, date and time of the day;
sextant;
celestial globe;
chronometer;
radionavigation system;
direction finder;
stop-watch timer.

With the help of Student WorkPlace Software and enclosed manuals, in accordance with the terms of the task assigned by the instructor, student has the possibility:

оdetermine sextant corrections by horizon, star, Sun observation;
determine chronometer correction;
measure celestial altitudes with the use of sextant;
correct celestial altitudes measured by sextant;
пadjust altitudes measured by sextant to one zenith;
figure out celestial bodies for astro-navigational observations with the help of celestial globe;
calculate longitudinal solar altitude time;
determinate latitude by the Polar star height or by longitudinal solar altitude;
determinate sunrise/sunset time;
determinate time of the beginning and ending of observation (nautical twilight );
train for celestial observation with the help of celestial globe;
obtain coordinates fixed by observation by Sumner position lines;
study the starry arch in any hemisphere;
compass correction determination by sunrise azimuth or by celestial body bearing in selectable azimuth.

Besides there is a possibility of investigation which way the following cases disposition are maintained: misalignment of the sextant limb plane pipe visual axis, out-of-squareness of the sextant limb big plane mirror, out-of-squareness of the sextant limb small plane mirror.

Main advantages

Operations visualization of position-finding and adjustment reckoning.
Execution of measurements at any point of the Earth's surface.
Possibility of immediate tasks execution for reckoning and evaluation of results.
Low requirements for computer equipment.
