MYQ-02A High Precision Atmospheric Processor

The air data processor is designed to detect the total static pressure or distributed pressure of the airflow approaching an aircraft, thereby enabling the measurement of key flight parameters including Mach number, barometric altitude, vertical velocity, and indicated airspeed. The barometric pressure signals, which are collected from outside the aircraft and serve as the input for the air data processor, undergo processing via a solving circuit. Based on specific algorithms—tailored to factors such as the number of pressure channels, the carrier’s shape, and the distribution of pressure-measuring points—the processor outputs atmospheric parameters (e.g., static pressure, total pressure, barometric altitude, indicated airspeed, and flight Mach number) and transmits these parameters to the flight control unit in digital form.
The MYQ-02A High-Precision Air Data Processor, developed by Hangtai Technology, utilizes a high-precision vibrating cylinder pressure sensor and is specifically engineered for large unmanned aerial vehicles (UAVs). Compliant with aerospace standards, this product can withstand harsh operating environments and is widely applicable for atmospheric parameter measurement in aerospace scenarios, such as high-altitude high-speed UAVs and near-space ultra-long endurance UAVs. Key characteristics of the MYQ-02A include its compact size, lightweight design, high measurement accuracy, wide operational range, and excellent stability.
