FrontGrade CTO on Satellite Edge Processing
FrontGrade CTO Lorne Graves says satellites need more onboard processing to handle threats and data from megaconstellations.
FrontGrade Technologies Chief Technology Officer Lorne Graves discussed the evolving need for onboard satellite processing in a recent SpaceNews podcast. The conversation centered on adapting to megaconstellations and electronic warfare threats.
Graves explained that the rise of large satellite constellations is fundamentally changing requirements. These networks generate vast amounts of data. Transmitting all this raw information to the ground for processing is often impractical. The solution is moving more computational capability onto the satellites themselves. This is known as processing at the edge.
Benefits of Onboard Processing
Shifting analysis to the spacecraft offers clear advantages. It dramatically reduces the volume of data that needs to be downlinked. This saves precious bandwidth. More importantly, it enables faster decision-making. A satellite can identify a critical event and respond almost immediately. There is no long delay waiting for commands from Earth.
This capability is crucial for national security. Graves highlighted lessons from electronic warfare. Adversaries can jam communications or spoof signals. A satellite with robust onboard processing can autonomously navigate these threats. It can maintain its mission even when the link to ground control is compromised. FrontGrade's history is relevant here. The company's technology has supported every U.S. crewed space mission since Apollo 11.
The Threat Environment
The space domain is becoming more contested. Graves described a landscape where satellites must be more resilient. They cannot be entirely dependent on vulnerable ground stations. Processing power allows for smarter, more autonomous spacecraft. These satellites can interpret sensor data in real time. They can distinguish between normal operations and potential attacks.
This shift requires new hardware. Processors must be both powerful and radiation-hardened to survive in space. They also need to be modular and scalable. System architects can find relevant stats on radiation tolerance and processing benchmarks. This lets customers build systems that can be upgraded or reconfigured for different missions.
Learning from Other Domains
Graves emphasized that the space industry should not work in isolation. The challenges of secure, distributed processing are not unique. The podcast explored parallels with electronic warfare and other defense sectors. Techniques for secure data handling and autonomous operation are being developed across the Department of Defense. The space community can adapt these approaches.
The goal is to move critical capabilities to the mission faster. FrontGrade's current work spans RF systems, mission processing, microelectronics, and motion control. The focus is on creating modular architectures. This allows for the rapid integration of new processing technologies as they become available. For teams building these systems, tracking component fixtures and integration schedules is vital.
The interview was part of the 'Space Minds' podcast. This weekly series from SpaceNews features interviews with scientists, founders, and other space experts. New episodes are released every Thursday.
