Temperature-compensated crystal oscillators (TCXOs) play an important role in Global Navigation Satellite Systems (GNSS). These systems provide global positioning, navigation, and time synchronization services to all operational satellite navigation systems, including multiple constellations of satellites orbiting the Earth.
The core principle of a GNSS is based on measuring distances between satellites and receivers. Each satellite sends its position and time signals to a receiver. By obtaining signals from multiple satellites, the receiver calculates the time difference and use triangulation to determine the exact position (longitude, latitude, and altitude).
These satellites deliver precise time and location data, enabling ground-based equipment, like smartphones, car navigation systems and GPS devices, to calculate their current position.
TCXOs are necessary for effective GNSS performance, contributing to accurate positioning and navigation. TCXOs are critical in helping to provide:
GNSS technology is found in a broad and essential range of applications, including:
Here are some examples of systems around the world that are based on a GNSS:
