Space-Based Infrared System (SBIRS)
Northrop Grumman Corporation has delivered the first SBIRS geosynchronous orbit (GEO) payload to prime contractor Lockheed Martin for integration into the spacecraft and final system-level testing. 
The GEO-1 payload consists of both a scanning sensor and a staring sensor, and other key spacecraft subsystems and electronics including a pointing and control assembly (PCA). The scanning sensor is designed for continuous observation and surveillance of traditional intercontinental ballistic missile threats. The staring sensor is designed to detect very low signature, short-burn-duration theater missiles. Together, the sensors contain nearly one million detector elements in their two focal planes.
SBIRS High
Northrop Grumman Electronics Systems sector provides the infrared payload, electronics and ground processing for the mission data processor to the Lockheed Martin-led Space-Based Infrared System (SBIRS) High team. SBIRS High is a series of high Earth orbiting satellites whose sensitive infrared sensors can detect the launch of strategic and theater ballistic missiles from space and pass the time and location of launch to battlefield commanders.
Space Tracking and Surveillance System
SBIRS High works in conjunction with the Space Tracking and Surveillance System (STSS), a constellation of missile tracking satellites capable of performing missile defense, missile tracking, technical intelligence and battlespace characterization.The company's Space Technology sector is leading the STSS industry team. Electronic Systems will contribute to the systems engineering, ground segment and algorithms. In addition, the sector will be one of two competitors for the sensor payload and ground station data processing program. 
The sector also provides space-borne sensing for early warning systems, weather and ground systems that process C4ISR data from space-based platforms for high-priority U.S. government national security programs.
For more than 30 years, Electronic Systems has supplied the sensors for scores of space-based missions, including the Gemini rendezvous radar, the cloud imager for the Defense Meteorological Satellite Program, the infrared sensor for the Defense Support Program and the multispectral/hyperspectral cameras for the Orb View-3 and Orb View-4 commercial remote sensing program.
