Parsons Corporation Achieves Milestone with SPARTAN Antenna Deployment

On March 18, 2026, Parsons Corporation (NYSE: PSN) announced a major advancement in satellite command and control technology with the successful integration and operational acceptance of the Raven Defense S-Band Phased Array Receive and Transmit Antenna Node, known as SPARTAN. This state-of-the-art antenna has been incorporated into Parsons' OrbitXchange™ global antenna network, marking a significant leap forward in the company's space engineering solutions.

The SPARTAN system represents the first operational deployment of a phased-array-fed parabolic antenna designed to support satellite commanding, telemetry, and mission data collection. This innovative technology features a 6-meter full-motion parabolic dish equipped with a phased-array feed, enabling it to generate eight electronically steerable downlink beams alongside a dedicated uplink beam. This capability allows for the simultaneous support of multiple spacecraft, setting a new standard in satellite communications.

Ed Baron, Senior Vice President of Parsons’ Space Engineering Solutions, highlighted the strategic advantages of the SPARTAN system. "This is a significant capability jump for OrbitXchange and for our customers," he remarked. The SPARTAN antenna not only offers the performance of traditional parabolic antennas at a competitive price point but also introduces the ability to command and control multiple satellites concurrently—a feature absent in conventional ground antennas.

Baron further explained the flexible design of the SPARTAN system, which allows for retrofitting legacy antennas, scaling to larger apertures for missions extending into cislunar space, or chaining multiple units together to ensure continuous coverage across the geosynchronous belt.

Designed specifically to meet the rigorous requirements of national security space missions, the initial SPARTAN installation significantly enhances Parsons' OrbitXchange capabilities, providing the largest Unified S-Band and Space Ground Link System (SGLS) commercial capability available for U.S. government customers. The system's design is adaptable to additional frequency bands, ensuring it meets emerging mission needs effectively.

Equipped with the Parsons Mission Link Modem (MLM)—a software-defined radio—the SPARTAN system offers flexible signal processing capabilities and supports a diverse range of mission sets, waveforms, and data rates. This adaptability is crucial as government and commercial customers increasingly require versatile communication solutions.

Baron expressed enthusiasm for the partnership with Raven Defense, noting that the antenna was customized for satellite commanding and telemetry operations directly from the production line. "We look forward to expanding our partnership with Raven Defense and deploying additional SPARTAN systems to meet the accelerating needs of our government and commercial customers," he stated.

Parsons Corporation's deployment of the SPARTAN antenna system marks a pivotal moment in the evolution of satellite command and control technologies. By leveraging decades of expertise in national security and space engineering, Parsons continues to deliver innovative solutions that enhance satellite operations and support the evolving requirements of government and commercial missions. As the demand for advanced space capabilities grows, Parsons is poised to remain at the forefront of this critical industry.
