L3Harris Technologies and Comtech Telecommunications have unveiled an innovative embeddable multi-orbit satellite communications (SATCOM) modem tailored for military applications. This advanced 5650C2/MP modem facilitates connectivity across various satellite orbits, including medium Earth orbit, geostationary orbit, and highly elliptical orbit, all within a single, compact system. Such versatility is crucial for maintaining robust communication capabilities in contested environments.
The new modem is built on Comtech’s cutting-edge software-defined architecture, allowing it to support multiple waveforms. Notably, it includes Direct Sequence Spread Spectrum technology, which enables secure and anti-jam transmission, enhancing the reliability of communications in challenging conditions. Additionally, the system is designed to be reconfigurable to meet specific mission requirements, offering further adaptability in the field.
Integration capabilities are a key feature of the modem, as it works seamlessly with L3Harris’ tactical terminals, such as the Panther and Hawkeye man-portable systems. This compatibility allows for rapid deployment with minimal additional hardware, a crucial factor for military operations that demand swift responsiveness.
The modem is currently undergoing certification for the U.S. Space Force’s Wideband Global SATCOM (WGS) constellation. It is also under evaluation for integration with the European Satellite Company’s mPower constellation, highlighting its international relevance and potential.
Chris Aebli, president of Mission Critical Communications at L3Harris, emphasized the significance of this technological collaboration, stating that it enhances operator effectiveness and contributes to overall mission success. He noted that the modem’s unique capabilities make it the only SATCOM solution capable of functioning between both the mGS and WGS constellations.
Daniel Gizinski, President of the Satellite & Space Communications Segment at Comtech, echoed these sentiments, pointing out the growing demand for flexible and resilient communications solutions within contested environments. He stressed that this new modem exemplifies how partnerships in the industry can spur innovation, providing customers with the necessary flexibility and reliability to remain connected and mission-ready.
