HawkEye 360 has announced the planned decommissioning of the firm’s pioneering Cluster 1 Pathfinder satellites by the end of 2024 — this decommissioning marks the conclusion of the first-generation satellite cluster that transformed the commercial RF industry and laid the foundation for the company’s growth and innovation.
In recognition of the significant achievements made during its service, HawkEye 360 will celebrate the satellites retirement this December, honoring the enduring legacy of the Pathfinder trio.
Launched in December of 2018, the Pathfinder satellites were HawkEye 360’s proof-of-concept mission. Pathfinder demonstrated that a commercial company could reliably provide RF data, a capability previously dominated by the government and classified sectors. Initially designed for a two-year mission, these resilient satellites far exceeded their life expectancy, thanks to the high-quality bus provided by Space Flight Laboratory (SFL). This novel design allowed Pathfinder to continue supporting research and became fully operational, successfully serving critical customer needs and supporting key missions worldwide.
Pathfinder’s success laid a strong foundation for HawkEye 360’s subsequent growth. The innovative approach to hardware development—enhancing antennas, filters, and frequency coverage — allowed the company to advance its capabilities continually. During Pathfinder’s six-year mission, HawkEye 360 validated the commercial viability of RF data collection. It helped expand the HawkEye 360 constellation to 31 satellites, setting new standards for reliability and performance in the industry.
As Pathfinder retires, Cluster 11 will take its place, significantly enhancing the constellation’s capabilities. Scheduled to launch by the end of 2024, Cluster 11 incorporates the latest technology and will operate in a mid-inclination orbit, complementing Clusters 6, 8, and 9 to expand coverage in the high-demand equatorial region.
Featuring a new antenna, the company is actively experimenting with global lower-frequency collection, enhancing the ability to detect and analyze a broader range of RF signals. Notably, this transition will not affect our customers, as our new clusters offer increased capacity to fulfill the mission previously handled by Cluster 1. Cluster 11, the first cluster vibe-tested at HawkEye 360’s Herndon facility, will usher in the company’s new era of advanced technology.
