In addition to hundreds of OCTs, these facilities can concurrently accommodate large-quantity fabrication of constellation-ready satellites ranging from cubesats to ESPA-Grande class satellites.
“GA-EMS is fully committed to the deployment of optical communication as the backbone of future national security space architectures,” stated Scott Forney, president of GA-EMS. “Leveraging 20 years of experience developing multi-domain optical technologies, GA- EMS’ low SWaP-C OCT is technologically advanced and designed such that it allows for greater production efficiencies to support large scale satellite constellation programs. The combination of a mission focused, manufacturable OCT design and large-capacity development infrastructure, means that we can meet requirements and deliver hundreds of units every year on budget and on time.”
“The GA-EMS OCT is easily integrated onto a variety of satellites providing customers with tremendous flexibility in platform configurations to drive costs down and meet mission objectives,” added Nick Bucci, vice president of Missile Defense and Space Systems.
Mission Microwave High Power BUCs to Replace TWT Amplifiers
Mission Microwave Technologies, LLC, a manufacturer of SSPAs and BUCs, has received follow-on orders from a government contractor to provide Ku and Ka-band BUCs as components of complex SATCOM transportable terminals in support of the US Army.
This third order for the ongoing program is valued at $6 million. At the completion of this third tranche of BUCs, the program will be roughly one- third complete.
Mission’s signature Stinger, Javelin, Titan, and MOAB products have been designed into families of terminals across X-, Ku- and Ka-band frequencies and are the high power product of choice for tactical end-users.
The common form factor and interfaces of these products allows SATCOM terminal designers to create flexible platforms, eliminating the need to re-engineer the implementation when missions change.
“Mission Microwave worked closely with one of the industry’s leading system integrators of these large transportable terminals to complete the certification cycle; allowing the replacement of Ku-band and Ka- band TWT BUCs with Mission’s MOAB Ku-band 400 watt BUC and Titan 200 watt Ka-band Solid State BUCs. Now that the authorization has been completed by the government program office, the value proposition of smaller, lighter and highly efficient high power Solid State amplifiers are available to the critical elements of the Army’s SATCOM terminal network. We look forward to continuing this progress with higher power capabilities on our customers’ new transportable terminals in the near future,” said Francis Auricchio, President and CEO of Mission Microwave.

Lockheed Martin is leveraging commercial best practices, strong partnerships, a broad supply chain and leadership expertise, to bring 5G connectivity and capabilities to the defense community, rapidly and affordably.
The team rapidly prototyped, tested and validated this system in a matter of months compared to what previously took years.
WAEFR also features:
• High performance gain of a dish with the beam agility of an ESA
• Low Size Weight and Power (SWAP) common product solution to accommodate any orbital altitude or ground terminal application
• Advances in 3D-printing technology and accelerated parts production This type of antenna will also benefit the broader communications and ISR communities by providing a more reliable scanning solution compared to gimbaled designs.
“We adopted a commercial mindset to quickly mature this technology and discovered there were multiple use cases and applications that could benefit from this new hybrid antenna,” said Chris Herring, vice president of advanced program development at Lockheed Martin Space.
“5G.MIL technologies like this will bring greater connectivity, faster and more reliable networks, and new data capabilities to support our customers as they navigate the complexity of 21st century battlefields.”
“The primary benefit of the WAEFR approach is accomplishing more mission with fewer resources,” said Thomas Hand, Ph.D., associate technical fellow at Lockheed Martin Space. “While state of the art ESA solutions can address more demanding link performance, capacity, and solutions can address more demanding link performance, capacity, and data rates using multiple agile analog beams, they do so at a premium.”

TTTech’s Radiation-Hardened Network Controllers For Space
In Series Production Electronic components used in a spacecraft need to fulfill very high quality and production standards and work reliably in extremely harsh environments. TTTech Aerospace and the firm’s semiconductor partner, STMicroelectronics, have completed the development, industrialization and qualification of highly integrated, radiation- hardened TTEthernet® Systems on Chip (SoCs) network controllers.
They are used in deterministic, fault-tolerant, Ethernet-based networks for space applications. The successfully qualified TTESwitch Controller HiRel and TTEEnd System Controller HiRel are already being used in the avionics systems of two major launcher programs and on one robotic program. With the qualification successfully completed, TTESwitch Controller HiRel and TTEEnd System Controller HiRel are now available as series products, ready for use in a broad variety of space flight applications, such as launch vehicles, satellites or robotic applications.
TTTech Aerospace’s TTEthernet® network controllers (TTEEnd System Controller HiRel and TTESwitch Controller HiRel) uniquely act as Systems on Chip (SoCs). They support three traffic classes: standard Ethernet (IEEE802.3), rate constrained and time-triggered traffic (SAE AS6802) for a wide variety of networking applications. Thanks to their high Gigabit/second bandwidths, the network controllers are ideal for real-time transfer of high data payloads (e.g. high-resolution images and videos) and hard real-time transmission of safety-critical control data with short latency over one single network. A wide range of interfaces allows for high flexibility in connecting to electronics hardware for easy integration.
The TTEEnd System Controller HiRel and TTESwitch Controller HiRel are equipped with an integrated LEON2 CPU for system management and diagnostics that ensures automatic time synchronization of the application to the network. The chip is based on a radiation-hardened design process and packaged in a cost-efficient plastic package. This ensures reliability in harsh environments requiring high radiation tolerance for applications like launch vehicles and low earth orbit (LEO) satellites.
“Our TTEthernet® SoCs network controllers are the first of their kind worldwide to enter series production. They act as a ‘central nervous system’ connecting all systems in the spacecraft. Their modular and deterministic nature supports design optimization and a significant reduction in software complexity and equipment size,” said Christian Fidi, Senior Vice President Business Unit Aerospace, TTTe.
