This edition highlights ATDI's latest developments in spectrum engineering, software innovation and industry engagement.
Discover the newest enhancements in HTZ, including advanced radar interference analysis for wind farms, updated propagation models, improved reporting and workflow efficiencies, and support for the latest ETSI standards to deliver more accurate network planning.
We also showcase ATDI's continued contribution to the ITU-R, where our technical expertise helps shape international Fixed Service standards and supports the future of wireless communications.
Read about our participation at Eurosatory through GICAT, where discussions with defence leaders highlighted the growing importance of spectrum management and electromagnetic operations, and look ahead to EW Live 2026, where we'll be demonstrating our latest spectrum engineering capabilities.
Finally, explore the latest additions to ATDI's global map data library, featuring new high-resolution datasets that support accurate modelling, interference analysis, and reliable network design.
HTZ v.2606.6 and Above – Feature Enhancements Now AvailableHTZ continues to evolve with new features and enhancements designed to improve the user experience, strengthen RF analysis capabilities, and support critical spectrum management activities.
Calculations - TOOLS > Propagation Model - Updated the ITU SSN values used by the ITU-R P.1147 propagation model, ensuring calculations reflect the latest recommended parameters.
Spectrum Management - Wind Farm Interference Analysis for Radar Systems
STATION POPUP MENU > COVERAGE > Windfarm C/N+I or I/N Map (Bi-static)
The existing C/I Map option has been replaced by a new C/N+I Map, providing a more realistic assessment of radar performance in the presence of wind turbines.
New radar-specific capabilities include:
For radar stations:
Target RCS and height are automatically derived from the radar parameters and associated coverage settings.
The Uplink Coverage option has also been extended to radar objects when operating in C/N+I mode. In this scenario:
As with downlink analysis, beamforming mode automatically orients the antenna towards the selected map point.
Interface - ETSI TS/RIF Masks - Reduced the number of TS/RIF files required for NFD calculations using ETSI masks, aligning processing with the latest ETSI EN 302 217-2 V3.4.1 (July 2025) standard.
Bulk Station Updates - OBJECT > Change from TXT File
Extended the import functionality to allow modification of both station azimuth and tilt using the following format:
Callsign<SEP>Tilt (°)<SEP>Azimuth (°)<CR>
Layer Data Extraction - REPORT > Extract Layers from X,Y File
Added the ability to export the following information for each point contained within a CSV file: Altitude (m)/Clutter code/Clutter height (m)/Building height (m)/Result value.
Input format: X<SEP>Y<SEP>Name<CR>
Station List View - Coverage thresholds can now be displayed in either dBµV/m or dBm, depending on the selected application settings.
RF Calculators - TOOLS > RF Calculators > Power Converter - Added a new conversion utility for converting dBµV/m to dBW/m²/Hz.
TS/RIF Convolution Matrix - Optimised the convolution matrix generation process by dynamically adjusting the calculation step size according to the smaller of the wanted and unwanted bandwidths, improving efficiency and accuracy.
Fixed - ETSI TS/RIF Files - Added support for the latest 2025 ETSI mask releases (TS and RIF files).
MICROWAVE > Interference MWL - Added support for the co-channel required protection ratio within the TD calculation method and associated reports.
Setting the value to -100 automatically retrieves the protection ratio from each microwave link's parameters using the C/I Req N=0 setting.
Mobile - PATH > Flight Track - When using Rx Mode (Mobile), reports now provide:
This improves visibility of individual interference contributors while retaining the overall interference assessment.
Tactical - OTM > Flight Track - When using Rx Mode (Mobile), reports now provide:
This enhancement mirrors the functionality available within the Mobile module, providing a clearer breakdown of interference sources.
As part of your maintenance contract, you have exclusive access to ATDI’s continually updated map data library, an essential resource for accurate and efficient network planning.

As a member of GICAT, the French land and air-land defence and security industry association, ATDI was pleased to participate in several high-level meetings at Eurosatory 2026. These engagements provided valuable opportunities to discuss the growing importance of spectrum management, electromagnetic operations, and mission-critical communications with senior French defence and government officials, as well as international delegations.
The discussions included representatives from COMCYBER, the French Army and the French Special Forces, all operating in an environment where control of the electromagnetic spectrum is critical to mission success.
ATDI's capabilities were recently demonstrated during Exercise ORION 2026, where its software supported the planning and analysis of communications and electromagnetic operations in high-intensity conflict scenarios. The exercise validated the ability to model contested electromagnetic environments, assess the impact of electronic warfare, and support mission planning before forces are deployed.
ATDI remains actively engaged in the work of ITU-R Study Group 5, contributing to the ongoing development of international recommendations and reports for the Fixed Service. During the latest 18-29 May period meetings, our expert Dr Mazar, serving as vice chair of Working Party 5C and chair of Working Group 5C-3, provided key technical contributions, including revisions:
These activities demonstrate ATDI's continued commitment to advancing spectrum engineering, supporting emerging technologies, and helping shape the future of international radiocommunication deliverables.
Next Stop: EW Live 2026 - 15–17 September, Tartu, EstoniaEW Live is one of Europe's premier electronic warfare events, bringing together military operators, defence organisations and technology providers for live demonstrations and hands-on evaluation of EW, SIGINT, COMINT, ELINT and spectrum operations capabilities.
Over the coming weeks, we'll be sharing more details about our participation, including the ATDI team attending, demonstrations planned for the event, and the technologies we'll be showcasing.
If you're planning to attend EW Live 2026, we'd be delighted to meet with you and discuss how ATDI can help support your spectrum management and electromagnetic operations requirements.
