Dominate the Space Domain

L3Harris Space Superiority

Space Control

L3Harris plays a key role in ensuring the U.S. and allies have freedom of action in space. The company also provides technology for the other side of that equation – denying that freedom to adversaries when needed. L3Harris provides a wide range of space control capabilities, including live, virtual, constructive environments for training and engineering, cybersecurity and program management. L3Harris is also at the forefront of space electronic warfare (EW), providing the first-ever ground-based satellite denial capability.

L3Harris Capabilities:

• Counter Communications System

• Space Test and Training Range

Space Domain Awareness

The key to dominating the space domain is knowing exactly what is in orbit. L3Harris technology detects, tracks and identifies all artificial objects in Earth orbit. The company provides innovative ground- and space-based sensors and algorithmic capabilities and tools to support rapid data acquisition, extraction and exploitation. L3Harris is also modernizing DoD sensors to bring Cold War-era sensors into today’s fight.

L3Harris Capabilities:

• Mission Planning Tool

• Advanced Radar Solutions for Space Domain Awareness

• Advanced Electro-optical System R&D and Sustainment for Space Domain Awareness

Operational Space Command and Control (C2)

L3Harris joins full SDA and space control resources to provide critical orbital analysis support, training and tools to all space C2. We support all levels of space C2 – tactical, operation and strategic – and continue to develop a training and wargaming environment to guide controllers and decision-makers.
