HELPING AIRPORTS OPERATE SAFELY

We have planned and modelled potential problems from wind farms for a number of developers and has provided advice on mitigation techniques.

Windfarms can be added to an HTZ communications project in a similar manner to radio stations, and the effect of the wind turbine on radar performance can be predicted using the “wind turbine radar constraints function”.

A point to point analysis can be performed for each receiver present on the map reporting the power of reflected signal level received from each wind turbine and emitted by each active transmitter using the “wind turbine interference” function.

NETWORK PLANNING MADE EASY

• HTZ communications supports every technology operating within the radio spectrum. This effectively means that analogue and digital
• technologies can be simulated using one software tool. The aeronautical propagation model in HTZ communications, is an add-on model to ATDI planning tools for use in the planning and coordination of aeronautical mobile systems. The model is compliant with ITU standards, and includes an optional model to account for terrain obstructions which could lead to excess losses in smooth Earth conditions.
• HTZ communications is able to simulate a significant number of ground to air services and provides peace of mind that critical systems can be deployed effectively.
• HTZ communications supports the following systems: VOR coverage – VHF Omni-directional range, ILS coverage – the Localizer array can be modelled as one single antenna if the equivalent pattern is known or as an array of antennas.
• HTZ communications is able to simulate different aspects of a radar network: radar coverage, radar interference on civilian networks, radar detection capacity. HTZ communications can automatically perform detection coverages at different heights in order to assess the performances of a radar system.

ACCURATELY IMPROVING MLAT PERFORMANCE

HTZ communications can assess the performance of every location by checking the profile of every pixel back to each sensor. An easy way to evaluate the requirement is to predict a coverage overlap. The locations with more than three overlaps are termed as good locations. Connection functions help the user manually inspect an aircraft location and display visually the sensors that can receive the signal.
