Functions & Mission Capabilities

• Autonomous Flight & Route Planning

  • Multi-waypoint mission setup (Route 8 main channel), AB and AB-T continuous tasks, one-click takeoff, landing, return-to-home.

  • Electronic fence: define safe boundaries; auto-return or hover on breach.

  • Low-voltage protection: automatic landing or return when battery falls below threshold.

  • Breakpoint resume: in case of interruption (e.g., signal loss, low voltage), intelligent resume from last waypoint.

  • Dynamic balance detection & management for payload-mounted systems (e.g., multi-pump sprayers).

  • Fruit-tree mode: specialized flight pattern for orchard spraying with optimized altitude hold and lateral turn adjustments.

• Manual Flight & Safety Protections

  • Manual control with integrated remote telemetry. Out-of-control protection triggers hover/return when lost signal.

  • Intelligent fault recovery: auto-detect and correct minor deviations, rollback on critical errors.

  • Electronic fence, no-fly zone compliance, obstacle avoidance integration (radar sensors).

• Payload Control

  • Dual water-pump control: support two pumps with independent on/off and flow regulation via CAN or PWM.

  • Intelligent reverse and throttling for pumps and spreaders.

  • Engine CAN equipment control: monitor engine status, adjust RPM, handle alarms.

• Sensor & Data Management

  • Integrates flow meters, weighing systems, level gauges for precise chemical application.

  • Real-time telemetry via 4G link or ground station: live status, GPS/RTK data, battery, pump flow, obstacle alerts.
