Solution Introduction

This solution proposes an intelligent UAV (drone) operation system based on the integration of Ultra-Wideband (UWB) positioning technology. It enables the device to operate flexibly and accurately both indoors and outdoors, significantly increasing the feasibility of drone-based cargo transportation projects. The solution completely overcomes the limitations of traditional satellite positioning methods (such as GPS), including signal loss and large errors in environments with many obstacles, while enhancing automation and operational efficiency. This is an important step forward in expanding UAV applications, ensuring security and occupational safety in modern industrial environments.

Nowadays, unmanned aerial vehicles (UAVs) are being extensively researched, developed, and applied in various fields such as monitoring, cargo transportation, infrastructure inspection, and security. Among these, positioning technology plays a critical role in determining the controllability, accuracy, and safety level of UAV operations.

Main System Components

Communication System

Consists of fixed Anchor devices installed at the site, using UWB technology to transmit and receive signals from mobile devices. This system serves as the foundation for positioning and data transmission. See details about the wireless communication solution here.

Drone Navigation Device

  • Continuously communicates with the communication system to update location.
  • Compact design, long battery life, and easy to integrate with various drone models.
  • High durability, waterproof, and shock-resistant — suitable for harsh industrial environments.

UWB Technology

Each unmanned aerial vehicle (UAV) is equipped with a UWB transceiver module and various functional sensors. During operation, the UAV measures the distance between itself and fixed Anchor stations along the flight path to calculate its precise position based on the reference system of these Anchors. The calculated position data, along with data from the UAV’s onboard sensors, is transmitted to the nearest Anchor stations and then forwarded to the data center via 4G/5G mobile networks.

The transceiver stations (ANCHOR) measure the distance to the DRONE using UWB technology and transmit the data to the SERVER via 4G/5G mobile networks or wired Ethernet. According to the system design, Anchors are strategically placed along the UAV’s flight corridor.

The data center (SERVER) communicates with both DRONES and ANCHORS, calculates drone positions, processes data, and supports user interaction applications.

The user interaction program (for managers, operators, contractors, etc.) available on the web platform or mobile app includes features such as control, management, monitoring, alerting, statistics, and flight history playback.

Operating Process

Data Collection

The navigation module communicates with the Anchor network and environmental sensors to collect location and obstacle data.

Precise Positioning

Anchors measure distances using UWB and send data to the server to calculate the drone’s coordinates in real time.

Analysis & Processing

The server aggregates and analyzes real-time location data, builds spatial maps, and calculates the optimal flight path for the drone.

Drone Navigation

The module receives data from the server to guide the drone accurately, avoid obstacles, and ensure safe operation inside the factory.
