Antaris

LANSDALE, PA — Antaris™ has unveiled comprehensive software support for the OpenLST software-defined radio, a pivotal tool introduced by Planet Labs in 2018. This release includes client libraries and drivers, designed to simplify the adoption of this open-source hardware for complex space missions. For Antaris customers, the transceiver is operational straight from the Antaris Cloud Platform.

Chris Rodriguez, president of The Space Crowd board, praised the initiative, stating, “OpenLST is a space-qualified, field-proven system in high demand by satellite operators around the world. By supporting this important technology through open-source software, Antaris is demonstrating its commitment to advancing open platform technologies that benefit everyone in the satellite industry.”

The software’s capabilities have been rigorously tested through Antaris TrueTwin™, a next-generation digital twinning environment that facilitates Full Mission Virtualization™. Antaris conducted high-fidelity simulations to validate the OpenLST software and hardware using both software-in-the-loop (SITL) and hardware-in-the-loop (HITL) tests. Furthermore, Antaris plans to deploy the OpenLST transceiver on its upcoming JANUS-2 mission, elevating the hardware to Technology Readiness Level (TRL) 9.

Tom Barton, CEO and Co-Founder of Antaris, highlighted the significance of these advancements, saying, “Thanks to Antaris TrueTwin™, the upgraded OpenLST radio has successfully undergone comprehensive system-level testing. Its integration on JANUS-2 highlights the precision and reliability of our high-fidelity simulations, and we’re excited to see it take flight soon.”

Brian Waldon, SVP of Engineering at Antaris, noted the broader impact of this release, stating, “This release unlocks new capabilities for all satellite operators. With flight-ready software, the Python libraries, Golang libraries, and the GNU Radio modules, we enable seamless ground system integration and empower engineers to operate reliably in space.”
