Push-to-Talk technology successfully demonstrated on Fleet Space’s Centauri-4 satellite
Fleet Space and SmartSat collaboration leads to breakthrough in tactical communication capabilities. SmartSat Cooperative Research Centre (SmartSat) has commended Fleet Space Technologies’ successful demonstration of satellite-enabled Push-to-Talk (PTT) capabilities as part of the Defence Space Command-funded ASCEND2LEO project. SmartSat and Safety from Space supported Fleet Space by adapting a variant of the ‘Beagle’ communications waveform, developed under previously SmartSat-funded projects, which Fleet Space implemented on the Centauri-4 satellite for this demonstration. This milestone in PTT capabilities opens a path to more secure, reliable, instantaneous communications across vast distances using highly advanced microsatellite architectures. ASCEND2LEO’s successful demonstration for the Australian Defence Force Joint Capabilities Group showed that Fleet Space’s Centauri satellites can be re-programmed to deliver high-quality, fit-for-purpose voice capabilities while in orbit. Voice capabilities for Fleet Space’s Centauri satellite were enabled via a software update, establishing a proof of concept for the Regenerative Voice System architecture underlying the ASCEND2LEO program. As a result, this demonstration validated the ability of highly adaptable microsatellite constellations to rapidly deliver purpose-built, high-quality SATCOM capabilities at scale to meet complex needs in diverse scenarios. ASCEND2LEO’s achievement was commended by Peter Kerr, SmartSat’s Defence & National Security Coordinator, who drove the concept for SmartSat’s involvement in the project by adapting and delivering the Beagle waveform. “Enabling an entirely new voice capability for a satellite that is already in orbit is a tremendous technical accomplishment. With this proof of concept, SmartSat is playing a critical role in helping the Australian industry develop SATCOM resiliency for Australian Defence and validate the Regenerative Voice System architecture, a powerful and ambitious approach undertaken by the ASCEND2LEO program.” During the live demonstration, hosted by the Defence Science & Technology Group (DSTG), Fleet Space’s PTT capabilities have met strict performance criteria for one-way voice transmission including voice quality, reliability, and link persistence across […]
