🔧 Component Overview
The DJI Agras Downward Radar Module is a core flight-safety component responsible for real-time ground sensing, altitude stabilization, and terrain following during spraying and spreading operations.
This module continuously scans the ground surface beneath the aircraft to:
- Maintain consistent spray height
- Adjust flight behavior over uneven terrain
- Support low-altitude precision under variable crop density
This is not an optional sensor on commercial aircraft — it is foundational to stable, compliant operation.
⚙️ Functional Purpose
Modern agricultural drones do not fly "by eye." They fly by sensor truth. The downward radar is the sensor that keeps the aircraft at the correct working height over terraces, slopes, and variable canopy — the foundation of consistent application rate and safe low-altitude flight.
⚠️ Common Replacement Indicators
When downward radar performance degrades, operators typically experience:
- Inconsistent spray height
- Terrain following errors
- Over- or under-application of chemicals
- Increased pilot workload and mission risk
📐 Specifications
- Component Type: Downward radar sensing module
- Function: Ground detection, altitude hold, terrain adaptation
- Compatibility: DJI Agras T100 / T70P
- Installation Location: Underside sensor array (airframe belly)
- Technology: Radar-based ground sensing optimized for agricultural environments
- Integration: Interfaces directly with flight controller and obstacle avoidance systems
Inspect before installation:
- Confirm the module and radome surface are free of cracks or shipping damage
- Clean the belly mounting area — chemical residue degrades sensing
- Review the orientation reference before seating the module
After installation:
- Power up and confirm the downward radar reports online with no errors
- Verify altitude hold and terrain-follow behavior in a controlled hover over known ground
- Fly a short variable-terrain test route before production spraying
🚜 Necessary For
This component is necessary inventory for:
- Commercial spray operators flying terrain-variable fields
- Contractors operating under FAA Part 137
- Fleet operators managing uptime across multiple aircraft
- Repair centers servicing impact, moisture, or sensor-error aircraft
Any operator flying without a verified, functioning downward radar module is accepting avoidable risk to both equipment and crop outcomes.
💡 Why This Part Matters
A compromised downward radar module leads to:
- Uneven chemical distribution
- Regulatory exposure due to inconsistent application height
- Increased stress on propulsion and spray systems
- Higher probability of mission aborts mid-route
Replacing the module restores predictable altitude control, protects expensive payload components, and preserves spray accuracy across long operations. This is one of those parts professionals keep on hand, not order after failure.
Read the ground. Hold the height. Follow the terrain. Apply every acre at spec.
