IOCAP

The Smart Way to Create HF Frequency Predictions

Ionospheric Characterisation Analysis and Prediction tool (IOCAP)

Imagine relying on a “wall of numbers” to find the best rush-hour route from your home to work, instead of using a navigation app which uses live traffic reports to calculate the fastest route as you drive. What navigation apps have done for modern commuting amid constantly changing traffic, SANSA engineers have done for a type of communication technology that relies on signals that travel via the ionosphere and are sensitive to constantly changing space weather.

This type of communication, called high-frequency (HF) radio, was common before satellite radio communication became the norm, particularly for long-distance communication. HF radio is of upmost importance in military and disaster relief communications, as shown recently during the Mozambique hurricane disaster, when cell phone communication systems became overloaded and satellite phones did not operate due to the heavy cloud cover.

In civil aviation many long-distance carriers keep contact with their base using HF radio. IOCAP can be used to calculate which frequency at any given point during the flight will provide the best communications. However, HF signal propagation (how these radio waves travel) is sensitive to changes in the ionosphere due to space weather. HF users require accurate forecasts of the conditions in the ionosphere that might affect the usable frequencies for their HF communications.

IOCAP is a modern, user-friendly HF frequency prediction application produced by SANSA as a proudly South African product.

IOCAP features a robust, proven prediction engine that provides dependable frequency predictions in the 3-30 MHz frequency band. Its primary aim is to make HF frequency predictions and their analyses accessible to HF operators of all experience levels.

It is simple to use and contains innovative features not found in any other HF prediction software.
