Product Description

Product Description

1. Overview

This product is a brand-new generation of handheld unmanned aerial vehicle (UAV) detection and positioning device. Through low-frequency detection technology, it enhances the FPV UAV detection capability, effectively detecting various types of low-frequency racing UAVs and decoding their first-person flight perspective images. This device integrates regulatory functions such as unmanned aerial vehicle (UAV) spectrum detection, protocol parsing, and RID identification. It can achieve real-time detection and early warning of over 900 types of UAVs, and accurately locate and track the trajectories of common UAVs and pilots (remote controls).
The entire device is only the size of a smart phone, weighing approximately 650 grams. It is equipped with a common frequency band detection antenna, making it easy to carry and long-lasting in battery life. It can be applied to low-altitude security operations in various scenarios.

3 FPV detection: capable of detecting and identifying homemade racing drones, real-time analysis of their first-person flight footage.
4 Pilot navigation^[4]: This product plans the route for tracking drone controllers with easy operation.
5 RID detection^[5]:This product is able to identify DJI drones (with OcuSync protocol), drones with RID, and the unique serial number (SN) of WIFI drones.
6 Comprehensive information[6]:Realtime display of the drone model, coordinates, velocity, altitude, pilot coordinates and so on.
7 Black and white list^[7]:Once a white list is set, the alarm of product will not be set off if the drone in white list is detected.
8 Early warning:The device will alarm by beeping or vibrating when detects the drone. 
9 Trajectory playback: Assists security personnel to analyze historical drone flight data.
10 History records:The detection results will be saved for review, including SN, model, frequency band, etc. 
11 Multiple languages:Supports English, Chinese, Russian, and Portuguese.
_{Notes
[1]-[7]: Only applies to DJI series with OcuSync protocols.
[5]: GB 42590-2023, ASTM F3411 Remote ID, ASD-STAN prEN 4709-002.}

4. Features

1 Racing drone detection: Newly upgraded low-frequency FPV detection capability, which can cover the frequency bands of most homemade racing drones. 

2 Image demodulation: Real-time parsing of the first-person view (FPV) flight footage of FPV drones, with clearer image demodulation. 

3 Portable and easy to use: When detecting and positioning common drones such as DJI and Autel, this device can operate normally without an external antenna, making it more portable and user-friendly. 

4 Comprehensive regulatory coverage: Capable of detecting over 900 types of drones, including DJI (including O4), Autel, Feimi, etc. 

5 Networking and interconnection: Can be connected to the low-altitude management platform to realize multi-device linkage and intelligent unified dispatching management of security zones. 

6 Mobile and portable: The device weighs only ~658g, is portable for individual soldiers, and can be used immediately after being turned on.
