Since the concept of 'low-altitude economy' was introduced in the 2010 'Research on China's General Aviation Development,' it has undergone 14 years of development. By 2024, the 'low-altitude economy' was officially listed as a new growth engine in the Chinese government work report, marking its emergence as a global focus. This trend presents significant opportunities and challenges for the crystal oscillator industry. The low-altitude economy refers to a comprehensive economic ecosystem driven by various manned and unmanned aerial vehicles operating at low altitudes, integrating sectors such as agriculture, inspection, firefighting, logistics, aviation, tourism, and emergency response. Crystal oscillators, with their high-precision time and frequency control capabilities, have become indispensable core components in this field.

1. Applications of Crystal Oscillators in the Low-Altitude Economy

Key products in the low-altitude economy include drones (consumer-grade, industrial-grade), helicopters, traditional fixed-wing aircraft, and eVTOLs (electric vertical take-off and landing vehicles). The diverse application scenarios encompass:

1. Logistics Delivery: The application of drones in logistics distribution fields such as express delivery and food delivery is becoming increasingly widespread.
   
   
2. Cultural and Tourism Consumption: Scenarios like aerial tours, parachuting, and flight services in cultural and tourism consumption.
   
   
3. Public Management: Drones are increasingly mature in applications such as environmental monitoring, urban planning, and traffic management.
   
   
4. Urban Air Mobility (UAM): Providing convenient urban transportation solutions through electric vertical take-off and landing aircraft (eVTOL) and drones.
   
   
5. Agricultural Plant Protection: Drones improve agricultural efficiency and precision through targeted pesticide application and extensive coverage, reducing chemical usage and environmental pollution.
   
   
6. Emergency Communication: Rapid deployment and response capabilities of drone communication systems accelerate rescue operations and enhance emergency response efficiency and reliability.
   
   
7. Public Services: Applications in aerial emergency rescue, medical assistance, police security, and government-related flights.
   
   

In these varied scenarios, flight devices rely on crystal oscillators to deliver stable and reliable clock signals, ensuring the smooth execution of critical tasks such as flight control, navigation, and data transmission. High precision, stability, reliability, and low power consumption are fundamental requirements for crystal oscillators in low-altitude devices. Specific scenarios impose stricter demands. For example, logistics drones operating in extreme weather conditions often use temperature-compensated crystal oscillators (TCXOs) to maintain stable and precise clock signals despite significant temperature fluctuations. In emergency communication or rescue operations, devices must withstand harsh environments such as high/low temperatures and electromagnetic interference, necessitating enhanced oscillator reliability and anti-interference capabilities.

As a core component, crystal oscillators not only provide stable clock signals for central processors but are also widely used in functional modules, including:

The low-altitude economy offers vast growth potential, and crystal oscillators will continue to serve as a critical technology, underpinning its development with precision and reliability.
