These tools are currently available to everyone. In the future, tool users will be asked to register. This will help us to understand who is using the tools and assist in our efforts to improve them. Your feedback on these tools will help too.
Note: The HF and Digital HF Prediction tools are designed for modern browsers. IE 9 and earlier are not supported (nor is IE compatibility mode).
|HF Prediction||HAP, Min-Max HAP, URSL, GRAFEX, Air Route, LAMP and Frequency selection.|
|Digital HF Prediction||Reliability and other features of digital HF radio.|
|VHF/UHF Area Prediction||Calculates and displays RF signal loss for VHF/UHF (30MHz - 3GHz).|
Consult each tool's Help for more detailed information on how to operate the tool. You can request additional HAP charts or website modifications by emailing SWS_Office@bom.gov.au.
For more detailed HF predictions including field strength predictions, you can purchase the SWS Advanced Stand Alone Prediction System (ASAPS). The SWS Ground Wave Prediction System (GWPS), which estimates ground wave range values under specified ground and operating conditions is also available for purchase. For more details on these software packages see:
SWS offers a consultancy service for organisations designing or upgrading an HF communication system. The in-house software tool Network to Area (N2A) has been used for many consultancies. N2A calculates predicted coverage and availability for an HF radio network. We also have advanced consultancy software for the prediction of digital HF and VHF-UHF propagation. Consultancies are undertaken on a cost-recovery basis.
