South Australia-based Fleet Space Technologies has used communications waveform technology Beagle to demonstrate satellite-enabled push-to-talk (PTT) capabilities to the Australian Defence Force (ADF).

understands Beagle is a design framework developed by Australian company Safety from Space to generate efficient radio frequency (RF) signals that can transmit small and large amounts of data. The radio signals are carried on electromagnetic waves and the data is encoded and mapped using modulation techniques to determine the form. The waveform generated is specified by a complex mathematical representation.

The Beagle waveform was applied on Fleet Space’s Centauri 4 low Earth orbit (LEO) satellite to deliver tactical PTT during the demonstration, which was announced by the company on 12 March. The demonstration was conducted as part of Defence Space Command’s (DSpC’s) ASCEND2LEO programme, which aims to develop a LEO satellite communication (satcom) system leveraging Centauri satellites to deliver tactical voice and data transmission where connectivity is limited.
