Frontgrade Gaisler and DELTATEC Enable Advanced Space Computing Across Multiple Missions

Göteborg, Sweden / Ans, Belgium — November 19, 2025 — Frontgrade Gaisler and DELTATEC are pleased to celebrate their successful collaboration in delivering high-performance computing solutions for space applications, with the GR712RC dual-core microprocessor at the heart of several flight-proven systems.

‍The GR712RC, developed by Frontgrade Gaisler and based on the fault-tolerant LEON3FT architecture, has been integrated into multiple Data Handling System (DHS) units designed by DELTATEC. These include one Payload Data Handling Unit (PDHU) and two On-Board Computers (OBCs) currently operating aboard ESA’s eSAIL mission, launched into Low Earth Orbit (LEO) in September 2020.

‍Moreover, DELTATEC recently delivered the Flight Model of the Mass Memory Unit for ESA’s Altius mission, demonstrating the versatility of the GR712RC microprocessor in multiple space applications. Other Frontgrade rad-hard components utilized in this platform are the 16Mb MRAM (UT8MR2M8), the 40Mb SRAM (UT8ER1M39M), the 16Mb SRAM (UT8R128K32) and the voltage supervisor (UT01VS50D).

‍“We are especially proud of how cost-efficient and versatile the GR712RC microprocessor is,” said Sandi Habinc, General Manager at Frontgrade Gaisler.

‍“Its flexibility allowed DELTATEC to deploy it across a range of computer systems, from payload data handling to mass memory units. This adaptability not only streamlines development but also supports long-term mission reliability and scalability,” adds Eric Callut, Senior Project Manager at DELTATEC.

‍Frontgrade Gaisler and DELTATEC continue to enable efficient and resilient satellite systems for current and future space missions worldwide, through advanced microprocessor technology and system design.
