ECDIS is one of the most complex and sophisticated navigational tools on board a ship today. All SOLAS-ships will be fitted with this equipment over the next few years. High quality training and instructions are therefore essential requirements and this is where this book can play an important role. The objective of the book is to impart practical hands-on knowledge about ECDIS. For less experienced users, the book will help to gain a profound overview of the principles of ECDIS navigation and the related challenges. However, it is likely that advanced ECDIS operators will also be able to find new answers and helpful suggestions for ECDIS navigation in this book. Based upon the principles of the IMO Model Course 1.27, the book is suitable for all kinds of ECDIS courses in different settings.

Even so, thorough knowledge of satellite navigation seems to be private to specialists like geodesists and manufacturers. The group of daily users of GPS systems and data however is becoming larger by the day.
