4 terms

low earth orbit technical

"18 missile warning and tracking satellites that will provide persistent detection"

Low Earth orbit (LEO) is the region of space close to Earth, roughly from about 160 to 2,000 kilometers above the surface, where satellites and spacecraft circle the planet quickly—think of it as a busy highway just overhead. It matters to investors because many communications, imaging and data services rely on satellites in LEO; their shorter lifespans, lower launch costs, crowded lanes and debris risks directly affect the cost, revenue potential and operational risks of companies that build, launch or use these satellites.

infrared sensing payloads technical

"provide infrared sensing payloads, onboard signal-processing capabilities"

Infrared sensing payloads are instruments or sensor packages that detect and measure infrared radiation, typically mounted on satellites, aircraft, drones, or vehicles to create heat-based images and data. They matter to investors because they enable applications like night-time imaging, temperature mapping, surveillance, environmental monitoring, and industrial inspections—similar to a high-tech thermometer or night-vision camera—so their performance, production costs, and demand affect revenue, contracts, and competitive position for companies that build or use them.

onboard digital signal processing technical

"payloads combine infrared sensing with onboard digital signal processing"

Onboard digital signal processing means the device contains built-in hardware and software that analyze, filter, compress or transform sensor, audio, video or telemetry data inside the product itself instead of sending raw data elsewhere. It matters to investors because that on-device processing can change a product’s performance, power needs, manufacturing cost, and competitive edge — like giving a gadget its own mini brain so it can work faster and send less data over a network.

hypersonic technical

"persistent detection and tracking of hypersonic and other advanced missile threats"

Hypersonic describes vehicles or weapons that travel at speeds greater than about five times the speed of sound (roughly over 3,800 mph), moving so fast they behave differently from ordinary aircraft. For investors it matters because development and deployment drive demand for specialized materials, engines, guidance systems and testing services, shaping defence and aerospace spending, supply chains and company valuations; think of it as the difference between a car and a supersonic bullet in terms of technical challenge and cost.

RESTON, Va., Aug. 3, 2026 /PRNewswire/ -- Building on a track record of delivering advanced sensing technologies for the Space Development Agency's (SDA) proliferated low Earth orbit architecture, Leidos (NYSE: LDOS) was selected by Sierra Space to provide infrared sensing payloads, onboard signal-processing capabilities and mission support for the for the Accelerated Missile Defense Tranche 3 (AMDT3) Tracking Layer.

Sierra Space will integrate Leidos' infrared sensing payloads into 18 missile warning and tracking satellites that will provide persistent detection and tracking of hypersonic and other advanced missile threats from low Earth orbit. Together, Sierra Space and Leidos are combining proven satellite integration and flight-tested sensing technologies to field operational capability for one of the nation's highest priorities in missile defense.

"AMDT3 will build upon proven technologies to accelerate global missile defense capability," said Cindy Gruensfelder, president of Leidos Defense. "Leidos has already demonstrated these technologies on orbit, and with Sierra Space, we will rapidly transition that proven capability into an operational missile defense constellation that will help protect the nation against advanced missile threats."

Leidos' payloads combine infrared sensing with onboard digital signal processing that enables mission-relevant tracking data to be generated directly aboard the satellite, reducing latency and allowing actionable tracking information to be delivered faster to the warfighter. The company will also provide ground support equipment, mission expertise, operations support and sustainment throughout the program.

The AMDT3 award extends Leidos' contributions across SDA tranches 0, 1 and 2, reflecting the customer's continued confidence in the company's proven performance and rapid execution. Leidos' four Tranche 0 payloads have successfully operated on orbit since 2023, producing tracks of real-world events. Leidos is also delivering 14 missile warning and tracking sensors for Tranche 1 and 16 for Tranche 2, plus two dedicated missile defense sensors for Tranche 2.

As SDA expands the tracking layer to provide greater global coverage and enhanced missile defense capabilities, Leidos' flight-proven technologies will help deliver the resilient, proliferated sensing architecture needed to support homeland defense, theater operations and the broader objectives of Golden Dome for America.

The AMDT3 award advances Leidos' NorthStar 2030 strategy by expanding the company's position in space sensing, onboard digital processing and integrated national security technologies while continuing its evolution from technology demonstration to operational missile defense capability.
