Application of Temperature-compensated Crystal Oscillator TCXO in Navigation/Positioning
2024-12-06

Temperature-compensated crystal oscillators (TCXO) are crucial in navigation and positioning devices. Their applications mainly include the following aspects:
1. High-precision signal generation: In GPS, Beidou and other navigation systems, TCXO provides the receiver with accurate reference frequencies to ensure the accuracy of signal processing.
2. Anti-temperature drift: TCXO maintains frequency stability through temperature compensation technology and adapts to the performance requirements of navigation devices in changeable environments.
3. Low power consumption design: In portable navigation devices (such as in-vehicle GPS and smart wear), TCXO's low power consumption characteristics extend battery life.
4. Diverse application scenarios: Widely used in positioning systems such as smartphones, drones and vehicles to everything, improving navigation performance and user experience. TCXO has become one of the core components of navigation and positioning equipment with its high stability, reliability and miniaturized design.

The crystal oscillator frequencies commonly used in navigation devices mainly include:
26 MHz: Widely used in GPS receivers to provide a stable reference frequency for RF circuits.
16.368 MHz and 19.2 MHz: Commonly found in GNSS modules to support multi-mode navigation systems (e.g. GPS, Beidou, GLONASS).
32.768 kHz: As a real-time clock (RTC) frequency source for low-power systems. These frequencies are widely used in vehicle navigation, smartphones, handheld positioning devices, and other fields due to their high stability and compatibility.
Hangjing can provide a variety of packages TCXO, stability ± 0.5ppm @-40 + 85C.
