SATELLITE COMPASS

Here is a compact and concise practical guide developed for those who need some introductory information about the GNSS transmitting devices commonly used onboard contemporary ships for the purpose of marine navigation. They say that the real revolution in the field of marine navigation actually took place with the invention of the marine compass some thousand years back, no one knows for sure when exactly.

Having the marine compass and the speed log, the seafarers got the opportunity to conduct much safer voyages. Another revolution occurred in the beginning of the last century when the hyberbolic radionavigation means, and then satellite navigation systems were presented, which eventually allowed to go without the historically traditional practice of dead reckoning.

In this guide the authors are trying to provide some short yet understandable explanations of the working principles of the modern satellite-based technologies and how they manage to comply with the heading data requirements.
