This edition brings some exciting news for our users. Over the summer, we released a significant update to our map data library, delivering richer, high-resolution datasets that significantly improve the accuracy and reliability of your planning projects. This update is a core value of the Maintenance Contract, ensuring you always have access to the very latest geospatial resources.
Alongside this, we’ve released new HTZ functions, including enhanced propagation modelling and updated MIMO array rejection calculations, delivering greater precision and efficiency in your workflows.
We’re also pleased to share three new electronic warfare video demonstrations: drone-mounted direction-finding using TDOA and AOA techniques, on-the-move jamming simulations, and MANET communications planning with automated optimisation.
Finally, ATDI will be exhibiting at several key events before the end of the year, including the UIC FRMCS Global Conference (Rail), MWC Las Vegas (Mobile), Comms Connect Melbourne (Mission Critical), and Saudi Rail 2025. We look forward to engaging with industry professionals across these diverse sectors.
From the ATDI team.
HTZ continues to evolve, with new features and modifications designed to enhance the user experience, improve RF analysis capabilities, and support critical spectrum management tasks.
Feature Enhancements Overview
Modify Clutter with SHP Points
Now adds only vegetation clutter codes based on point height (PointZ or DBF attribute). Codes created are 14, 8, and 5, depending on vegetation height.
Map Layer (F4) Update
The “OSM transport” server has been replaced by OSM Cycl, now including contour lines for enhanced map detail and usability.
Path Object – Variable Elevation
New option: Variable elevation (oblique flight) interpolates mobile height between waypoints. The previous option is now labelled “Variable elevation (horizontal flight).”
5G Station Parameters – gNB Tab
Overhead (%SS/PBCH) and xPDSCH values are now calculated automatically based on the frequency in use (FR1/FR2), as specified in 3GPP.
Export PNG Tiles with AI Mask Prediction
Now checks for existing clutter codes before downloading tiles, reducing redundant processing and improving performance in “whole project” mode.
MIMO Array Rejection (Modified Calculation)
Interference rejection is now calculated differently depending on antenna type and MIMO scheme, ensuring more accurate modelling of real-world scenarios
Command Line Interface
A new action code generates availability maps, providing detailed ASCII outputs on available and contiguous channels for faster spectrum analysis.
Propagation Model Update (ITU-R P.368-9)
Improvements to the GRWAVE model eliminates discontinuities when transitioning between different conductivity areas, resulting in smoother and more accurate propagation results.
Adaptive MIMO Switching
The Adaptive MIMO Switching (AAS) mode has been removed from SNIR and throughput calculations. Results now rely on station-defined parameters for arrays, layers, and MU.
Vector Layer Selection
Users can now filter vectors by string fields in “exact” or “contain” modes, improving map/vector data handling flexibility.
Subscriber Parameters Update
A new “Layers” parameter has been introduced for subscribers, enhancing accuracy in MIMO rejection and throughput calculations.
MIMO Array Rejection Calculations
Rejection is now consistently computed as Tx + Rx rejection, reflecting transmitter/receiver setup more precisely across stations, subscribers, and map points.
