The Rubin Observatory is a powerful ground telescope that will view more of the universe than all previous telescopes combined.

L3Harris built upon its world leadership in space-based optics to develop an advanced telescope optic for the observatory. The 3.5-meter secondary mirror and mirror cell assembly will help scientists explore the structure and evolution of the universe and the objects in it through one of this century’s most exciting astronomy projects.

The European Space Agency-led mission will observe the birth of galaxies, supermassive blackholes and the evolution of compact binaries with the world’s first space-based gravitational wave observatory.

Laser Interferometer Space Antenna (LISA)

Scheduled to launch in the 2030’s, LISA is comprised of a constellation of three spacecraft in an equilateral triangular, 2.5 million kilometers apart, in the same orbit as the Earth around the Sun but trailing the Earth by 20 degrees in orbital phase. LISA detects gravitational waves by measuring the displacements between pairs of satellites with laser beams sent through optical telescopes on each satellite. L3Harris will design, fabricate, align, test, verify and deliver one Telescope Structural/Thermal Model and two Engineering Development Unit (EDUT) telescopes for LISA.

JWST is a space-based observatory that will provide unprecedented images of the universe’s first stars and galaxies.

James Webb Space Telescope (JWST)

JWST’s large, infrared-optimized telescope designed to study the formation of the first stars and galaxies, the evolution of galaxies, the production of elements by stars and the process of star and planet formation. L3Harris is playing a critical role in the assembly, integration and testing of the telescope.

The Nancy Grace Roman Space Telescope will provide data that might settle some of the most enduring mysteries of the universe – dark energy, dark matter, exoplanets and undiscovered galaxies.

Nancy grace roman space telescope

L3Harris is responsible for some of the most important tasks to create the telescope, including assembling the primary mirror. L3Harris created hardware to accommodate and interact with the two main scientific instruments on the telescope: the Wide Field Instrument and the Coronagraph.

For 20 years, every United States Martian rover mission and orbiting spacecraft has used L3Harris transceivers.

Mars Rover Perseverance

L3Harris avionics, sensors and transceivers are key components in the Mars Perseverance mission, enabling unprecedented image and data capture as well as transmission to overhead orbiters. They provide the vital communication link between the surface of Mars and all of the science instruments, allowing the science data and images to be sent to the overhead obiters.

The Artemis II mission marks a new era for NASA’s manned spaceflight program with its new Space Launch System (SLS) and Orion spacecraft. It will also carry the first female astronaut to the moon.

Artemis II

L3Harris’ Mission Astronaut Communication System is providing the crucial audio communication system in the Orion spacecraft. It will connect astronauts and NASA during the Artemis II mission, a lunar flyby that will lead to a return to the moon and on to Mars.

Responsive Reconfigurable Payloads

Digital Engineering

Accelerating development cycles is critical to keeping up with rapidly evolving technology and threats. L3Harris leverages end-to-end digital engineering and digital twin technology to develop new capabilities with digital workflows in a virtual environment. By using high fidelity digital 3D CAD models, L3Harris can efficiently coordinate complex, multi-domain analysis for an entire system in real-time.

From complex modeling to comprehensive analysis, our modeling and simulation capabilities deliver new horizons in digital engineering.

Mission Modeling and Simulation

To inform decisions about the structure, context and behavior of a physical asset, L3Harris uses virtual information constructs known as digital twins. The digital half is dynamically updated with data from its physical twin throughout its life cycle to enable missions.

Digital Twins

L3Harris uses live, virtual and constructive models and simulations to depict a multi-domain operational scenario. Each element replicates a wide spectrum of military operations in different functional environments to understand and optimize systems and mission operations.

Simulation and Mission Analysis

To deliver applications and services at high velocity for our customers, L3Harris employs a DevOps approach. Unlike traditional software development infrastructure management processes, DevOps combines cultural philosophies, practices and tools to evolve and improve products at a faster pace.

Devops

To design, build, test and release products faster and more reliably, L3Harris uses a set of practices to combine FPGA development with system and software integration. FPGA DevOps enables certain steps of the FPGA development process to be automated, accelerated and/or standardized, which reduces program costs.

Field Programmable Gate Array (FPGA) DevOps

Model-based definition (MBD)

Unlike other methodologies that have historically required accompanying use of 2D engineering drawings to provide such details, digital engineering shifts the focus to having models as the record of authority, known as MBD, or digital product definition (DPD).

By using models (such as MCAD, ECAD and CAE, 3D product manufacturing information and associated metadata) within CAD software, L3Harris can define individual components and product assemblies. The types of information included are geometric dimensioning and tolerancing (GD&T), component level materials, assembly level bills of materials, engineering configurations, design intent, etc.

L3Harris’ integration services enables the “Digital Thread”- a communication framework that allows a connected data flow and integrated view of the asset’s data throughout its lifecycle across traditionally siloed functional perspectives. The Digital Thread concept raises the bar for delivering the right information to the right place at the right time.

Integration services

To support system requirements, design, analysis, verification and validation activities throughout a product’s lifecycle, L3Harris uses a formalized application of modeling known as MBSE. Beginning in the conceptual design phase and continuing throughout development and later lifecycle phases, MBSE enables early detection of defects, iterative design, reduction of rework and improved producibility leading to reduced cost and time to market.
