The sheets are designed to provide the navigator with a practical and clear work surface when observations from celestial bodies are to be translated into a geographical position on the map. <\/p>\n<p data-start=\"511\" data-end=\"884\">Using a sextant, chronometer and Nautical Almanac, the navigator can calculate position lines based on observations of the sun, moon, planets or navigational stars. These lines are drawn on plotting sheets, and the intersection of several position lines gives an estimated position. Plotting sheets are therefore a key tool in <strong data-start=\"854\" data-end=\"883\">classical celestial navigation<\/strong>.  <\/p>\n<p data-start=\"886\" data-end=\"1250\">Universal Plotting Sheets from <strong data-start=\"916\" data-end=\"935\">Cassens &amp; Plath<\/strong> are designed to be used worldwide, regardless of latitude. They provide a standardized grid that makes it easy to plot position lines accurately and clearly during navigation. This makes them suitable for practical navigation, maritime education and training in traditional navigation techniques.  <\/p>\n<p data-start=\"1252\" data-end=\"1593\">Cassens &amp; Plath is one of the world&#8217;s leading manufacturers of navigational instruments and their products are used by navigators, sailors and maritime educational institutions all over the world. <strong data-start=\"1437\" data-end=\"1466\">Universal Plotting Sheets<\/strong> are a useful supplement to sextants, nautical almanacs and sight reduction tables when working with astronomical observations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Navigation tables and plotting sheets for astronomical navigation and sextant use.<\/p>\n","protected":false},"featured_media":42730,"comment_status":"open","ping_status":"closed","template":"","meta":{"_uag_custom_page_level_css":""},"product_brand":[1379],"product_cat":[1101],"product_tag":[],"class_list":["post-50502","product","type-product","status-publish","has-post-thumbnail","product_brand-cassens-plath","product_cat-accessories-for-sextants","first","instock","taxable","shipping-taxable","purchasable","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 v27.8 (Yoast SEO v27.8) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Cassens &amp; Plath Universal Plotting Sheets - Plotting sheets for astronavigation<\/title>\n<meta name=\"description\" content=\"Cassens &amp; Plath Universal Plotting Sheets are used to plot position lines for astronomical navigation.
