VK VRT24-S1 — 24 GHz Terrain Following Radar

The VK VRT24-S1 is a professional FMCW radar altimeter designed for agricultural drones, industrial UAVs, and autonomous aerial platforms requiring accurate ground-distance measurements.

Operating at a center frequency of 24.125 GHz, the VRT24-S1 provides real-time altitude information for terrain-following operations, altitude stabilization, and precision landing applications.

With a measurement range of up to 100 meters, 50 Hz data updates, and a compact IP67-rated enclosure, the VRT24-S1 offers a reliable sensing solution for professional UAV integration.

Precision Terrain Following

The VRT24-S1 measures the distance between the aircraft and the ground, providing essential information for terrain-following flight operations.

When integrated with a compatible flight controller, the radar supports automatic altitude adjustments according to changes in ground elevation.

This capability is particularly useful for agricultural UAVs operating over uneven terrain, slopes, and fields with varying elevations.

24 GHz FMCW Radar Technology

The VRT24-S1 uses Frequency Modulated Continuous Wave (FMCW) radar technology to measure distance.

Unlike optical sensors, radar measurement does not depend on visible light, allowing the module to operate during nighttime missions and in challenging lighting conditions.

Operating Frequency: 24.125 GHz

FMCW technology provides continuous distance measurements for compatible flight-control applications.

Up to 100 m Measurement Range

The radar provides ground-distance measurements across a wide operating range.

Measurement Range: 0.6–100 m

Altitude Measurement Accuracy: ±0.1 m

This allows compatible UAV systems to monitor the distance between the aircraft and the terrain during different flight phases.

Actual measurement performance depends on surface characteristics, installation orientation, and environmental conditions.

50 Hz Real-Time Updates

The VRT24-S1 features a high-frequency data output designed for responsive altitude monitoring.

Output Frequency: 50 Hz

Data Latency: 100 ms

Frequent distance updates provide compatible flight controllers with the information needed for altitude regulation and terrain-following functions.

Precision Landing Support

The VRT24-S1 can provide ground-distance information during takeoff and landing operations.

When integrated with a compatible autopilot, the radar supports altitude monitoring during the final stages of descent.

This is particularly useful for industrial UAVs and autonomous aircraft requiring accurate low-altitude measurements.

The radar provides distance information; automatic landing functionality depends on the connected flight controller.

Reliable Outdoor Performance

Radar sensing provides advantages in environments where optical distance sensors may be affected by lighting conditions.

The VRT24-S1 is suitable for applications involving:

Nighttime Operations

Strong Sunlight

Dusty Environments

Variable Terrain Conditions

Agricultural Field Operations

Industrial UAV Missions

Actual sensing performance can still be affected by environmental conditions and the characteristics of the measured surface.

CAN Bus Communication

The VRT24-S1 features a CAN communication interface for integration with compatible UAV flight control systems.

CAN communication provides a digital connection suitable for professional aircraft equipped with multiple electronic components.

Communication Interface: CAN Bus

Compatibility with the selected flight controller and firmware must be verified before installation.

Wide Operating Voltage

The module supports a wide input voltage range, simplifying integration into different aircraft power architectures.

Operating Voltage: 5–28 V

Power Consumption: 1.5 W at 25°C

This low-power design makes the radar suitable for professional UAV applications where electrical efficiency is important.

IP67 Protection

The VRT24-S1 features an IP67-rated enclosure designed for demanding outdoor environments.

The enclosure provides protection against dust ingress and temporary water immersion under the conditions specified by the IP67 standard.

This makes the radar suitable for agricultural and industrial UAV applications exposed to dust and moisture.

Compact & Lightweight Design

The VRT24-S1 features a compact construction designed for integration into professional UAV platforms.

Dimensions: 82.4 × 74.2 × 20 mm

Weight: 50 g

Its lightweight design minimizes additional payload requirements while providing accurate ground-distance measurements.

Agricultural UAV Applications

The VRT24-S1 is particularly suitable for agricultural drones requiring consistent flight height above the ground.

Typical applications include:

Agricultural Spraying

Fertilizer Distribution

Seed Spreading

Orchard Operations

Automated Field Coverage

Terrain-Following Missions

By providing ground-distance information, the radar supports compatible systems in maintaining the desired operating height over changing terrain.

Industrial UAV Applications

The VRT24-S1 can also be integrated into industrial UAVs requiring accurate altitude measurements.

Applications include:

Industrial Inspection

Autonomous Landing

Infrastructure Monitoring

Altitude Stabilization

UAV Logistics

Autonomous Flight Development
