Satellites will be able to alter their mission on orbit with new Lockheed Martin technology
Lockheed Martin (NYSE: LMT) has announced a new generation of space technology that will launch this year that will allow satellites to change their missions in orbit.
Satellites that launched one, ten or even 15 years ago largely have the same capability they had when they lifted off. That’s changing with new architecture that will allow users to 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.
This year, Lockheed Martin is integrating SmartSat technology on ten programs and counting, including the Linus and Pony Express smallsats, which will be the first to launch. These are rapid-prototype, testbed satellites using internal research and development funding, ready for 2019 launches on the first LM 50 smallsat buses:
• The Linus project delivers two 12U cubesats performing a technology demonstration mission, validating SmartSat capabilities as well as 3D-printed spacecraft components.
• Pony Express builds multiple 6U satellites destined for a low Earth orbit and will space qualify state-of-the-art networking technologies. Pony Express 1 is a pathfinder for a software-defined payload that will test cloud computing infrastructure and was developed in nine months. Follow-on Pony Express missions will prove out RF-enabled swarming formations and space-to-space networking.
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. This is a technology that enables a single computer to virtually operate multiple servers 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.
Rick Ambrose,EVP of Lockheed Martin Space, said this new type of satellite acts more like a smartphone. Add a SmartSat app to a satellite on-orbit and the mission is changed. The company is the first to deploy this groundbreaking technology on multiple missions. SmartSat will give customers unparalleled resiliency and flexibility for changing mission needs and technology and unlocks even greater processing power in space. SmartSat is a major step forward in our journey to completely transform the way we design, build and deliver satellites.
Ambrose added that the LM 50 bus is the perfect platform for testing this new, groundbreaking technology. Lockheed Martin is self-funding these missions to demonstrate a number of new capabilities that can plug into any satellite in the firm’s fleet, from the LM 50 smallsat to the flagship LM 2100. The same technology plugs into ground stations, improving space-ground integration, as well as one day be able to connect directly with planes, ships and ground vehicles, connecting front-line users to the power of space like never before.
Taking 3D Printing into Series Production is Thales Alenia Space
Thales Alenia Space first used additive manufacturing a few years ago with the 3D-printed aluminum antenna brackets for the TurkmenAlem/MonacoSAT satellite, launched in 2015, and the polymer tube supports for the Iridium® NEXT constellation.
The Koreasat 5A and 7 telecommunication satellites, orbited in 2017, featured the largest 3D-printed spacecraft parts ever manufactured in Europe at the time.
Today, Thales Alenia Space is taking 3D printing into series production to make components for telecom satellites built on the company’s new all-electric Spacebus Neo platform.
Spacebus Neo will feature four reaction wheel brackets made of aluminum and 16 antenna deployment and pointing mechanism (ADPM) brackets: four in aluminum and 12 in titanium.
The innovative 3D-printed reaction wheel bracket is designed to meet market demand for lower costs, now reduced by about 10 percent, and shorter lead times, with production schedules cut by one to two months. The new part is also 30 percent lighter and offers improved performance.
The metal powder-bed fusion technique used for these parts allows series production with a high degree of customization, making it possible to tailor designs to the exact requirements of each new mission.
The four reaction wheel brackets for each satellite, for example, are 3D printed as two sets of symmetrical parts, while the orientation angles and interfaces of the ADPM brackets can be adjusted to their specific function and position on each satellite.
Thales Alenia Space has also incorporated connector and cable fittings directly into the overall design, which is printed as a single-piece part,
thereby avoiding additional assembly requirements.
To produce these large (466 x 367 x 403 mm) reaction wheel brackets, the biggest powder-bed 3D printer in Europe has been installed and signed off — an Xline 2000R metal 3D printer from Concept Laser, which has a build chamber of 800 x 400 x 500 mm.
The first four parts have already been integrated on Eutelsat’s Konnect satellite, which was successfully mated earlier this month. Other Spacebus Neo platforms will also feature organically designed 3D-printed parts in the near future.
Philippe Sicard, engineer at Eutelsat, said the company is now fully involved in the development and use of 3D-printed satellite parts at all stages of the process, from design to final delivery. These parts are recognizable by their highly specific design. To ensure the most stringent quality standards, the overall process and individual components are robustly traceable and Eutelsat has established a comprehensive testing and inspection process.
