Prediction Tools

IPS provides the following online prediction services:

HF Systems Tool	Description
Hourly Area Prediction	Hourly Area Prediction (HAP). A base to area HF prediction of the optimum working frequency, for each UT hour.
Min-Max (Area of Coverage) HAP	Minimum to maximum area of coverage prediction for each frequency in the set, for a given UT hour.
URSL	point to point HF prediction, listing the Upper, Recommended, Secondary and Lower (URSL) HF frequencies.
GRAFEX Prediction	detailed HF point to point prediction, including the ALF, OWF for each hour, and take-off angles.
Air Route Chart	HF prediction for communication between a base and an aircraft.
RAAF Air Route Chart	HF prediction for communication between a base and a transport aircraft from a list of routes.
Local Area Mobile Prediction	Local Area Mobile Prediction (LAMP) is for HF communication within 1000km of a selected location
HF Network Frequency Selection	Given a set of HF network circuits, selects recommended frequencies for long term HF operation.

Click on the tools "Help" button for more detailed information on how to operate the tool. You can request additional HAP charts or website modifications by emailing office@ips.gov.au.

For more detailed HF predictions including field strength predictions, you can purchase the IPS Advanced Stand Alone Prediction System for AUD375. The IPS Ground Wave prediction System (GWPS), which estimates ground wave range values under specified ground and operating conditions is also available for purchase for AUD54. For more details on these software packages see:

If there is a grey area where the prediction tool would normally be then download and install the latest Java Runtime Environment (JRE) from http://www.java.com

You can also check your Java Virtual Machine at:

http://www.java.com/en/download/help/testvm.jsp

        1. If you see an animated dancing "Duke" in motion under
        the heading "Test your JVM" then the IPS applet should work.

        2. If no animation is visible then follow the "download and install
        instructions". On the next page click on "Download instructions"
        then select the JRE for your operating system most commonly,
        "Windows automatic download and Installation Instructions for the
        Java 2 Runtime Enviroment, standard edition (JRE)".
        Follow the instructions from here on.
