In the early years, people relied on paper maps for self-driving trips. However, paper maps cannot be used to check routes while driving, and cannot quickly determine the current location. With the continuous development and progress of technology, navigation devices have quietly entered people's daily lives, bringing great convenience. Next, let's talk about the role of crystal oscillators in navigation devices.
First, the crystal oscillator provides an accurate time reference in the navigation device. By synchronizing with the external GPS satellite, the crystal oscillator can ensure that the time inside the navigation device is consistent with the global standard time. This is essential for the normal operation of the navigation device because it needs to accurately calculate information such as position, speed and direction.
Secondly, the crystal oscillator also provides a stable frequency signal. In radio navigation equipment, the crystal oscillator acts as an oscillator to generate a stable oscillation frequency. These frequency signals are used to modulate and demodulate wireless signals to achieve communication with navigation satellites or ground base stations. The stability and accuracy of the crystal oscillator are essential to ensure reliable communication between navigation equipment and the outside world.
In addition, crystal oscillators also play the role of frequency synthesis in radio navigation equipment. By combining multiple crystal oscillators together, higher frequency band signals can be generated to meet the needs of different navigation systems. This frequency synthesis technology enables radio navigation equipment to operate in a wide frequency range, improving the flexibility and adaptability of the navigation system.
Crystal oscillators play an important role in providing accurate time reference and stable frequency signals in radio navigation equipment. Its stability, accuracy and frequency synthesis capability are essential to ensure the normal operation of navigation equipment and reliable communication with the outside world. Therefore, crystal oscillators play an indispensable role in radio navigation equipment.
