Astronomical navigation : François Meyrier
Even if today's electronic devices are very reliable, it is still essential (and sometimes compulsory) to know the techniques of positioning with the help of a sextant, a watch, a calculator and the ephemeris. In this manual you will find the basic principles of navigation based on the observation of the Sun, planets and stars.

<h2>GPS is a great navigation aid. However, it is important to know how to use it and to identify the risks in order to better prevent them.</h2>
<p>Learn how to use all the GPS functions, and at a glance on your screen you will see where you are and where you are going, how long it will take you to get there and what time you will be in port. As your boat progresses, the various displays, figures and graphs show the constantly changing data, which is both fascinating and reassuring.</p>
<p>As an everyday tool, GPS has become commonplace for road traffic or nature walks. Its nautical use, however, remains the most sophisticated of all, along with air navigation. At sea, a lack of settings, a handling error or a wrong reading can result in a shipwreck, with much more serious consequences than getting lost in the open country. Marine sense - a mixture of thoughtful analysis of all the information on board, observation of the maritime environment and constant sensory monitoring - consists first and foremost in never relying on a single instrument, even if it is as precise and magical as the GPS. When the reefs appear in front of the bow, it is too late to wonder if the position displayed on the screen is really accurate...</p>
<p>This special edition is aimed at beginners as well as those who already use a GPS on a regular basis but who do not check its correct operation, rarely pay attention to its settings and hardly use its advanced functions...</p>
