AeroShield™RF Drone Detection/Tracking Solution
Available for C-UAS System Integrators

AeroShield combines both hardware and software to provide a comprehensive solution for passive RF detection and tracking of drone activity. Offered as a flexible API and demonstration program, AeroShield fills a critical need for system integrators (C-UAS) to provide a comprehensive solution for drone mitigation. Anritsu supplies indoor and outdoor remote spectrum monitor hardware (RSMs) along with AeroShield software to provide drone detection and tracking capabilities for system integrators. Unlike many RF drone solutions currently on the market, AeroShield is the culmination of over 20 years of test and measurement receiver design and software development. Each RSM is rigorously tested over temperature extremes, EMI immunity and emissions with specs designed to detect and track drones in a variety of RF environments.

Time Difference of Arrival (TDOA) is used to constantly geo-locate drone positions using its video signal.

All elements needed by the system integrator to incorporate both receivers and software are available in an Application Programming Interface (API). Example source code, training materials, simulators and a demonstration package are provided to allow seamless integration into the integrator’s system level software.

AeroShield Advantage

TDOA Geolocation

Time Difference of Arrival algorithm is used for drone tracking. Rather than providing only bearing information, as used with Angle of Arrival (AOA), TDOA provides a fixed geo-location position. For tracking purposes, TDOA measurements are continuously updated to provide the path flown while in the area under drone protection. To perform TDOA measurements, three or more RSM units are needed.

Drone reports can be saved as kml, htm, or csv files.

Application Programming Interface (API)

The API provides the programmer with a library of building blocks to develop all needed functions for RF detection and tracking of drones. These building blocks are used to create the programs for detecting/geo-locating RF video signals transmitted by the drone. The API functions include all software applications for generating drone positions as well as full control over all relevant hardware settings. AeroShield is designed as a .NET DLL that can be linked and included in end-user system integrator applications. Anritsu ships a demo application that illustrates how various functions operate.

Additionally an AeroShield TCP/IP API interface is provided which allows external programs running on difference PC (but on the same network) to access and control AeroShield applications. The TCP/IP interface is built on a raw Ethernet socket. Various widely used command and control function are provided. These include functions for setting frequency masks (used in drone detection), reading drone GPS positions, turning RSM on/off, etc. A sample demo program is shown here. This client can be used for demonstrating AeroShield to end customers. All commands used in the demo functionality as available for incorporating into the system integrator’s software.

Remote Spectrum Monitors

Anritsu offers four models of spectrum monitoring receiver hardware. These include the following devices:
  • MS27100A - Anritsu’s MS27100A is a remote spectrum monitor designed for OEM applications. The solution can be integrated and branded into a user’s own enclosure or used as a stand-alone monitor is areas where space is at a premium.
  • MS27101A - The Anritsu Remote Specrtum Monitor MS27101A is a small form-factor spectrum monitor designed for remote applications. This monitor is used for indoor applications and comes with an optionally available bracket kit for rackmounting.
  • MS27102A - The Anritsu MS27102A is a remote spectrum monitor designed for remote outdoor applications. This monitor is rated to the IP67 standard, being dust tight (no ingress of dust) and water resistant. Each port on the unit is ruggedized and weatherized. Ports include power, RF Input(s), Gbit Ethernet, and GPS antenna. The MS27102A works in the most extreme weather conditions with guaranteed performance anywhere and anytime.
  • MS27103A - The Anritsu MS27103A is a multiple RF input spectrum monitor ideal for measuring signals from multiple antennas. The solution provides 12 RF input ports as a standard configuration and is typically used with a three-sector BTS cellular architecture with multiple carriers per sector. A high-speed switch is placed in the monitor to provide measurement capability for each RF input. This electronic switch can move from port to port in approximately 300 nS. A greater than 30 dB isolation is provided between each RF input port to assure the integrity of the measurement. Option 424 allows the MS27103A to be upgraded to 24 RF input ports.


A fully functional simulator is provided with AeroShield. This allows the user to develop customized scenarios for RSM deployment for sites considered to be sensitive to drone incursions. An example of a simulator display is shown in the picture here. The flight path of the drone path can be configured along with the positioning of the remote spectrum monitor hardware.
