Abstract

The paper presents the "Navigator" software system developed at the IAA RAS. The Navigator system allows you to solve 12 typical tasks of naval astronavigation related to determining the ship location and compass correction. The list of tasks also includes differential methods for processing observations. The tasks are solved on the basis of observations of the altitudes and azimuths of the Sun, Moon, five planets and navigation stars. For the task chosen, an optimal selection of luminaries is proposed by default for observations that give the highest result. Calculations are carried out on the domestic fundamental ephemeris of the Sun, Moon and EPM2021 planets. Ephemeris calculations are based on the recommendations of the XXIII and XXIV General Assemblies of the International Astronomical Union. The star catalog is composed of the stars from the list of the “Astronomical Yearbook” and some additional stars up to 6m from the list of the “Astronomical Yearbook”, as well as the stars from the Yale catalog and the Hipparcos catalog. The Navigator system can also be used to assess the astronautical situation using the Planetarium window with the image of the visible planisphere, as well as to calculate the lighting conditions and ephemeris data of the stars at a given place for a given moment in time. In addition to special windows, brief information about the luminary can be obtained directly in the Planetarium window. The presence of a reference window in the form of an interactive explanation for the “Naval Astronomical Yearbook”, which allows you to calculate ephemeris from examples, makes the system, in fact, an electronic version of the “Naval Astronomical Yearbook”. Interaction with the operator is provided through an interactive graphical interface. Input data can not only be entered from the window, but also from a file. The results of the solution are displayed on the screen, and are also presented in graphical (for individual tasks) and text form, in the form of a protocol and an archive of astrodefinitions, which can be opened for viewing on the Window Manager tab. You can select the time scale and geographic coordinate system convenient for the user in the Settings window. In the same window, corrections to universal time are entered.

AB  - The paper presents the "Navigator" software system developed at the
IAA RAS. The Navigator system allows you to solve 12 typical tasks of
naval astronavigation related to determining the ship location and
compass correction. The list of tasks also includes differential
methods for processing observations. The tasks are solved on the
basis of observations of the altitudes and azimuths of the Sun, Moon,
five planets and navigation stars. For the task chosen, an optimal
selection of luminaries is proposed by default for observations that
give the highest result.  Calculations are carried out on the
domestic fundamental ephemeris of the Sun, Moon and EPM2021 planets.
Ephemeris calculations are based on the recommendations of the XXIII
and XXIV General Assemblies of the International Astronomical Union.
The star catalog is composed of the stars from the list of the
“Astronomical Yearbook” and some additional stars up to 6m from the
list of the “Astronomical Yearbook”, as well as the stars from the
Yale catalog and the Hipparcos catalog.  The Navigator system can
also be used to assess the astronautical situation using the
Planetarium window with the image of the visible planisphere, as well
as to calculate the lighting conditions and ephemeris data of the
stars at a given place for a given moment in time. In addition to
special windows, brief information about the luminary can be obtained
directly in the Planetarium window. The presence of a reference
window in the form of an interactive explanation for the “Naval
Astronomical Yearbook”, which allows you to calculate ephemeris from
examples, makes the system, in fact, an electronic version of the
“Naval Astronomical Yearbook”.  Interaction with the operator is
provided through an interactive graphical interface. Input data can
not only be entered from the window, but also from a file. The
results of the solution are displayed on the screen, and are also
presented in graphical (for individual tasks) and text form, in the
form of a protocol and an archive of astrodefinitions, which can be
opened for viewing on the Window Manager tab. You can select the time
scale and geographic coordinate system convenient for the user in the
Settings window. In the same window, corrections to universal time
are entered.
