Lockheed Martin announces its first smart satellites
- March 21, 2019
Lockheed Martin has announced a new generation of space technology launching this year that will allow satellites to change their missions in orbit.
Satellites that launched one, ten or even fifteen years ago largely have the same capability they had when they lifted off. That’s changing with new architecture that will let users add capability and assign new missions with a software push, just like adding an app on a smartphone. This new tech, called SmartSat, is a software-defined satellite architecture that will boost capability for payloads on several pioneering nanosats ready for launch this year.
“Imagine a new type of satellite that acts more like a smartphone. Add a SmartSat app to your satellite in-orbit, and you’ve changed the mission,” said Rick Ambrose, executive vice president of Lockheed Martin Space. “We are the first to deploy this groundbreaking technology on multiple missions. SmartSat will give our customers unparalleled resiliency and flexibility for changing mission needs and technology, and it unlocks even greater processing power in space.”
Cyber security is at the core of this new technology. SmartSat-enabled satellites can reset themselves faster, diagnose issues with greater precision and back each other up when needed, significantly enhancing resiliency. Satellites can also better detect and defend against cyber threats autonomously, and on-board cyber defenses can be updated regularly to address new threats.
SmartSat uses a hypervisor to securely containerize virtual machines. It’s a technology that lets a single computer operate multiple servers virtually to maximize memory, on-board processing and network bandwidth. It takes advantage of multi-core processing, something new to space. That lets satellites process more data in orbit so they can beam down just the most critical and relevant information—saving bandwidth costs and reducing the burden on ground station analysts, and ultimately opening the door for tomorrow’s data centers in space.
SmartSat uses a high-power, radiation-hardened computer developed by the National Science Foundation’s Center for Space, High-performance, and Resilient Computing, or SHREC. Lockheed Martin helps fund SHREC research, and in turn gains access to world-class technologies and student researchers.
