The minimum order quantity (MOQ) is observed to be low, ranging from 1 to 2 units, which suggests that buyers can procure single units for pilot testing or small-scale operations without significant volume commitments. However, bulk orders may offer better pricing tiers, though specific volume discounts are not explicitly detailed in the provided data.

Typical Applications and Operational Efficiency

Agricultural UAVs are designed for a variety of applications, primarily centered around crop spraying, pest control, and fertilizer spreading. The liquid contained in the spray tank typically includes disinfectants, medicines, and liquid fertilizers. The spraying shape is often sector-based, allowing for precise application over specific areas of a field. The operational efficiency of these drones is a major selling point, with observed rates ranging from 7 to 10 hectares per hour. This efficiency is achieved through the combination of wide spray widths, high flight speeds, and automated flight paths.

The positioning system plays a vital role in application accuracy. Models utilizing GPS, Glonass, or RTK (Real-Time Kinematic) systems with dual antennas can achieve spraying accuracy within ±10 cm. This level of precision is essential for minimizing chemical overlap and ensuring uniform coverage. The terrain following capability, supported by radar and ultrasonic sensors, allows the drone to maintain a consistent height above the crop canopy, which is critical for effective droplet deposition and preventing damage to the crops.
