Written by Ivan Dedeken, the book explains how to determine position using celestial bodies such as the sun, moon, planets and stars. The content is adapted for practical use at sea, with explanations of the sextant, nautical almanacs and calculation methods, presented in an educational and understandable way. The second edition has been further developed with clearer explanations and improved structure, and serves as both a textbook and reference work. Astronavigation is particularly relevant for navigators and long-distance sailors who want solid expertise in traditional navigation, either as the main method or as a safe backup to electronic systems.    <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Norwegian textbook in astronomical navigation &#8211; a practical introduction to navigation with the sun, moon and stars.<\/p>\n","protected":false},"featured_media":39101,"comment_status":"open","ping_status":"closed","template":"","meta":{"_uag_custom_page_level_css":""},"product_brand":[1411],"product_cat":[1082],"product_tag":[],"class_list":{"0":"post-53333","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-nautisk-forlag","7":"product_cat-navigation-and-seamanship","8":"product_shipping_class-boxship","9":"pa_produsent-nautisk-forlag","11":"first","12":"instock","13":"taxable","14":"shipping-taxable","15":"purchasable","16":"product-type-simple"},"composite_virtual":false,"composite_layout":"","composite_add_to_cart_form_location":"","composite_editable_in_cart":false,"composite_sold_individually_context":"","composite_shop_price_calc":"","composite_components":[],"composite_scenarios":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.2 (Yoast SEO v27.2) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Astronavigation - traditional navigation with sextant | Kart.no<\/title>\n<meta name=\"description\" content=\"Norwegian textbook on astronomical navigation.
