Passive RF Drone Detection in Saudi Arabia

Secure your site with passive RF drone detection in Saudi Arabia. Our Terra Drone sensors identify threats 24/7 without jamming or signal interference.

BENEFITS

Gain Airspace Awareness Without Emissions Through Passive RF Detection

We use GACA-certified, listen-only Terra Drone sensors for safe drone detection. It is ideal for sites where active radar may disrupt aviation signals.

Listen Only, Zero Emissions

Our passive RF systems quietly monitor drone commands and video links without transmitting anything. This keeps you completely invisible to intruders while preventing interference with airport ILS, Wi-Fi, or CST-regulated spectrums.

100 MHz to 6 GHz Coverage

A single Terra Drone sensor scans the complete RF spectrum (100 MHz to 6 GHz). Whether it's a standard DJI model, a custom FPV, or a DIY build, our system detects it across all commercial and amateur bands.

2 to 6 km Detection Radius Per Sensor

Depending on the drone model and environment, each FTD1 node can detect threats up to 6 km away. You can easily scale this from a single facility to a full city-wide network.

Under 1 Second Refresh Rate

With a refresh rate of under one second, your security team always sees a real-time, moving map. Instant alerts notify your SOC console the moment a drone is detected.

Low False Alarm Rate

Say goodbye to constant false alarms. Our system averages just one false alert per day per node, using a smart signature library and whitelist rules to filter out your authorized drones and background noise.

Swarm Tracking for 10+ Drones

Facing a coordinated drone swarm? Our system easily tracks 10 or more drones simultaneously. Each drone appears on your live map, allowing your team to prioritize and respond effectively.

CHALLENGES

Why Traditional Airspace Security Falls Short

Cameras can’t look up, and active radar alerts intruders or disrupts flights. With passive RF, we ensure drones never reach your facility unseen.

Invisible Low-Altitude Intrusions

Modern commercial and DIY drones easily fly under traditional radar and slip past ground patrols. They often reach critical assets like flare stacks or VIP zones long before security sees them.

Active Radar Alerts the Intruder

Hostile operators can detect the signals emitted by active radar, allowing them to hide or change their approach. Our passive RF method keeps your entire detection layer completely covert.

ILS and Aviation Interference Risk

Any system that emits signals near an airport risks interfering with critical ILS and aviation links. Listen-only passive RF detection completely avoids this danger by transmitting absolutely nothing.

Non-DJI, FPV, and DIY Drones

Custom FPVs and DIY drones often lack Remote IDs, making them invisible to standard systems. We use an evolving signature library across a wide spectrum to catch these unseen threats.

Hobbyist vs Hostile Look the Same

A simple blip on a screen can't tell you if a drone is a harmless hobbyist, an authorized contractor, or a real threat. Without identification, your team can't coordinate the right response.

Swarms Overwhelm Single Sensors

Standard detectors get easily overwhelmed when an organized swarm of 10 or more drones approaches. You need our networked, TDOA-ready meshes to maintain full control and situational awareness.

TECHNIQUES & METHODS

Seamless Passive RF Detection Capabilities

Sensing, identification, and tracking via networked Terra Drone hardware. See TDOA pilot localization and RF mitigation for the full chain.

Listen Only RF Perimeter Monitoring

Terra Drone sensors cover all essential frequencies while operating entirely in listen-only mode. This keeps your security covert and prevents any disruption to site Wi-Fi, cellular networks, or critical airport signals.

Signature-Library Identification

We instantly match detections against a live, ever-updating signature library of DJI models, custom FPVs, and DIY builds. You see the drone's identity, model, and frequency band on your console almost immediately.

Remote ID Decoding and Whitelist Policy

Remote ID broadcasts from cooperative drones (commercial fleets, authorized inspection vendors) are decoded and matched against the site whitelist. Authorized flights surface on the map as green; unknown drones trigger the alert escalation path.

Networked Mesh and TDOA-Ready Geometry

A standard mesh of four or more FTD1 nodes provides overlapping, TDOA-ready coverage across your facility. This flexible network can scale smoothly from a single building to a massive city-wide deployment.

Swarm Tracking and Live Counter-UAS Map

Our system smoothly tracks swarms of 10 or more drones simultaneously. Your live map clearly plots friendly drones in green and unknown intruders in red, helping your team focus on the real threats first.

Central Console and Alert Escalation

Everything feeds into one intuitive SOC console complete with audit logs and whitelist updates. Your team can seamlessly escalate threats from basic alerts to location tracking and regulated mitigation, all within one platform.

Finding the Right Terra Drone Sensors for Your Site

We tailor Terra Drone sensor networks to your site’s unique RF environment and threat profile, scaling easily from 4-node setups to city-wide meshes.

Oil & Gas Facilities

We secure refineries and tank farms using FTD1 meshes that detect threats silently. Our systems never interfere with your critical process radios or alert hostile operators.

Airports and Aviation

We provide completely listen-only coverage around terminals and approach paths. This ensures robust security without any risk of ILS or VHF interference.

Critical Infrastructure and Government

We protect power plants and government campuses with networked detection. Built-in whitelists easily manage your maintenance drones while audit logs ensure you remain fully compliant.

VIP, Events, and Border Zones

Need rapid, portable security? Our briefcase-sized passive RF systems perfectly complement fixed meshes for VIP motorcades, large events, and remote borders without requiring heavy civil works.

HOW IT DEPLOYS

How Passive RF Drone Detection Deploys at a Saudi Airport

Here is an illustrative example of how Terra Drone passive RF sensors can protect Saudi airports without ILS interference. Sizing requires an NDA.

The Goal

We continuously monitor your approach paths and terminal airspace using a silent, listen-only sensor layer. It is the only safe detection approach that completely avoids interfering with critical ILS and aviation links.

Sensor Node: Zero Emission

We deploy Terra Drone FTD1 and FD1 sensors across your perimeter and gate zones. Because they operate in a strict listen-only mode with zero emissions, they are perfectly safe to use next to sensitive ILS and VHF links.

Detect-Only Default Near ILS

Our passive RF system runs in detect-only mode by default, ensuring absolute safety near approach paths. Any active mitigation is carefully coordinated with your airport security teams and GACA regulations.

Identification Layer

We identify standard and custom drones by cross-referencing signals with an extensive signature library. Authorized inspection drones show up green, while any unknown, unidentified drone instantly triggers an alert.

ATC and Security Integration

All live data, tracks, and alerts feed directly into your airport's SOC and ATC interfaces. We follow a clear, regulated escalation path: detect, locate, notify ATC, and coordinate with authorities when necessary.

AIRSPACE DETECTION ANSWERS

Frequently Asked Questions

Terra Drone sensors cover 100 MHz to 6 GHz in a single integrated unit, scanning drone command, telemetry, and video links. Detections are matched against a signature library covering DJI commercial models, custom FPV racing builds, and DIY drones, with updates pushed as new firmware and models appear.
Each Terra Drone FTD1 node covers a 2 to 6 km detection radius depending on drone model and urban clutter. A typical mesh uses 4 or more FTD1 nodes for overlapping coverage and TDOA-ready geometry. Networked meshes scale to multi-cell citywide deployments. Final sizing is set per site after an RF survey.
No. Passive RF detection is listen only and transmits nothing. The system monitors signals drones emit without affecting site Wi-Fi, cellular networks, or aviation systems such as ILS and VHF, and it stays invisible to the intruder. This is why passive RF is the default detection layer for airports and ILS-sensitive sites in Saudi Arabia.
Yes. Wideband passive RF across 100 MHz to 6 GHz captures custom FPV and DIY drone signals that do not broadcast Remote ID. The signature library is updated continuously as new models appear. For drones that emit very little RF, coverage is extended through complementary methods scoped during the site survey.
Terra Drone sensors maintain an average false-alarm rate of around one event per day per node, with a continuously updated signature library and whitelist rules suppressing noise from authorized fleets and known interference sources. Coordinated swarms of 10 or more drones are tracked simultaneously per platform cell, with each track plotted on a live counter-UAS map for operator prioritization.
