The Nautical Yearbook is the official manual for astronomical navigation in German ocean shipping .
Content and frequency of publication
The yearbook contains the ephemeris of the sun, moon, the four navigation planets (Venus, Mars, Jupiter and Saturn), the vernal equinox and the fixed coordinates of the navigation stars for each day of the year at one-hour intervals for Universal Time No.1 (UT1) and one Resolution of 0.1 ′ ( minutes of arc ). Using a sextant and an accurate clock, the astronomical location can be determined from this data.
The first edition appeared in 1850 for the observation year 1852 and was published by Carl Bremiker “at the instigation of the Royal Prussian Ministry of Trade, Industry and Public Works” . There have been slight title changes over the course of publication, and editors and publishers have fluctuated. The last editions are titled Nautical Yearbook. Ephemeris and tables for determining the time, longitude and latitude at sea based on astronomical observations and are published by the Federal Maritime and Hydrographic Agency (BSH); they appear in the previous year.
GDR
The Sea Hydrographic Service of the GDR published a comparable yearbook for the years 1951 to 1990 .
Aeronautical yearbook
From 1934 to 1941, the Deutsche Seewarte in Hamburg, the predecessor of the BSH, had an aeronautical yearbook on behalf of the Reich Aviation Ministry for the special purposes of navigation in aviation . Astronomical Ephemeris Issued; some parts are at the same time as the Manual of Air Navigation, Part E . In 1942 the Technical Office of the Reich Aviation Ministry published an aeronautical yearbook ... for hours , which was edited by the Rechlin Air Force Testing Center. For 1943 to 1945 the Technical Office of the Reich Aviation Ministry published an Aeronautical Yearbook 1 and ... 2 .
In 1929, the Lunar ephemeris for aviators was the first yearbook with information on the Greenwich hour angle. Shortly afterwards, a work in the form of a tear-off calendar came out in Japan - also for aviation - which combined the solar ephemeris on one sheet for a few days. Both ideas were taken up by the Deutsche Seewarte in 1933 in order to provide Lufthansa with easily manageable ephemeris for transocean approaches: one and two-hour hourly angle values for several stars per day were summarized on one sheet each. But only the second edition of the Aeronautical Yearbooks - published in 1935 for 1936 - was designed in this modern form. With these yearbooks, the Seewarte was the first to regularly publish ephemeris for aviation - they found many imitators.
