L3Harris has performed critical upgrades, such as improving radar resolution and enhancing sensor capabilities to detect and track smaller objects. These advancements are pivotal as new threats and challenges emerge in space.

Commercial Technology Integration

One of CODA’s standout features is its integration of commercial technologies. By partnering with tech companies, L3Harris has developed systems that process data more efficiently than ever before. For instance, CODA can work with commercial satellites and even academic research data, creating a holistic view of the space domain.

The result? Space operators are now equipped with a comprehensive understanding of the space environment, enabling faster and more accurate decision-making. As new data streams become available, L3Harris is prepared to adapt CODA, ensuring it remains a vital asset in space defense.

Preparing for Future Challenges

As space technology advances, so do the threats and challenges. L3Harris is committed to futureproofing SDA architecture. The company is developing new tools and capabilities to anticipate and mitigate risks proactively.

L3Harris is also exploring artificial intelligence (AI) and machine learning (ML) applications in SDA. These technologies can analyze patterns and predict potential issues before they arise, offering another layer of security for space assets.

Space Domain Awareness is crucial in today’s congested orbital environment. L3Harris, with its innovative technologies like CODA, is transforming space operations, making them more efficient and secure. The future of SDA lies in proactive threat anticipation, continuous innovation, and strategic partnerships. L3Harris’ dedication ensures that the U.S. maintains its edge in space operations, safeguarding critical assets and promoting space security.
