This course is one of the subjects of the Ocean-going Sailing (Grote Zeilvaart) program. There is an opportunity for interested parties to follow these lessons, either live or online.  <\/p>\n<p style=\"font-weight: 400;\">The module consists of 55 hours, spread over the months of October to March on Saturdays.<br \/>\nThe module is taught in <strong>English<\/strong> by Eef Willems.<\/p>\n<p><strong>Why Celestial Navigation?<\/strong><\/p>\n<p>Besides the fact that &#8216;traditional&#8217; navigation by the stars, sun, and moon is incredibly fun to do, we can conclude that it is actually a necessary skill in a changing world:<\/p>\n<p><em>&#8220;GPS spoofing is the intentional broadcasting of falsified GNSS (Global Navigation Satellite System) signals to make a receiver display an incorrect location or time. Unlike GPS jamming \u2013 where signals are blocked and the problem is immediately noticeable \u2013 GPS spoofing can lead a vehicle astray unnoticed.&#8221;  <\/em><\/p>\n<p><em>In a spoofing attack, an attacker broadcasts counterfeit GPS signals that are stronger than the original satellite signals. The navigation system then &#8216;jumps&#8217; to these false signals and displays manipulated location data.&#8221;  <\/em><\/p>\n<\/div><\/section><\/p><\/div><div  class='flex_column
