Advancing America’s Space Defense: L3Harris Completes Critical Milestone on Way to Delivering GBOSS Capability to the Warfighter
The U.S. Space Force has officially declared operational acceptance of a significant upgrade to L3Harris’ Ground-based Electro-Optical Deep Space Surveillance (GEODSS) system located at the Maui Space Surveillance Complex. This milestone represents a critical advancement in the nation’s defense capabilities concerning vital space assets amidst an increasingly contested space environment.
This upgrade confirms that the Ground-Based Optical Sensor Sensor (GBOSS) is now equipped to deliver timely and accurate space intelligence directly to Space Force operators. This enhancement facilitates expedited decision-making, elevates threat detection capabilities, and bolsters the protection of satellites that are integral to military operations and everyday life.
As adversaries augment their counter-space capabilities and orbital congestion intensifies, GBOSS provides warfighters with the precise tracking and characterization necessary to maintain space superiority. The system excels in detecting, identifying, and monitoring objects in deep space with unprecedented accuracy.
“GBOSS delivers exactly what today’s warfighters need: faster, more precise awareness in a domain where seconds matter,” stated Jeff Hanke, President of Space Systems at L3Harris. “This capability strengthens America’s ability to deter threats, protect vital space infrastructure, and ensure mission continuity for forces and citizens who rely on space every day.”
Enhancing America’s Space Vision
GBOSS enhances legacy GEODSS sensors with advanced optical technology, resulting in substantial improvements in sensitivity, responsiveness, and tracking accuracy. This upgrade is especially critical as space transitions from a previously permissive environment to an active warfighting domain.
From missile warning and intelligence gathering to secure communications, navigation, and weather monitoring, space systems are fundamental to joint force operations. GBOSS ensures these systems remain resilient, protected, and operational, even amidst evolving threats.
Global Surveillance and Strategic Advantage
Following the operational acceptance at White Sands Missile Range and the successful contractor verification testing at Maui, L3Harris demonstrates consistent execution across the global GEODSS network.
Collectively, these locations provide persistent and worldwide deep-space surveillance, enabling operators to swiftly identify anomalies, evade collisions, and respond to emerging threats, thereby protecting billions of dollars in space infrastructure and safeguarding critical missions.
With the introduction of GBOSS, L3Harris is delivering much more than just a sensor upgrade; it is providing a crucial operational advantage for America’s space defenders.
