Pre-atomic Timekeeping,ring, and the power of gravity. Clocks became essential for the synchronization of society, and for navigation at sea. Inexpensive yet precise quartz crystals found their way into wristwatches and many other objects in common use. Today even the most sophisticated atomic clocks require high-quality quartz crystals to serve as precise flywheels.

Global Navigation Satellite Systems (GNSS),in the term GNSS. Some of them were conceived in a competitive sense, however it was quickly realized that everyone would benefit if signals from all GNSS were used together. This chapter is a review of these rapidly evolving systems.
