7 terms

optical crosslinks technical

"The optical crosslinks allow GPS satellites to be able to directly communicate"

Optical crosslinks are chemical bonds formed between molecules when a material is exposed to light, causing its structure to lock together and become stronger or more stable. For investors, this matters because light-driven bonding can enable faster, cleaner manufacturing and longer-lasting medical or optical products—think of turning a soft gel into a firm, durable film with a flash of light—affecting product performance, production costs, and regulatory approval risks.

Digital Rubidium Atomic Frequency Standard technical

"equipped with a demonstration Digital Rubidium Atomic Frequency Standard clock"

A digital rubidium atomic frequency standard is a compact, highly stable timing device that uses the natural vibration frequency of rubidium atoms to generate an extremely accurate electronic clock signal. Think of it as a precision wristwatch for networks and equipment that keeps different systems in near-perfect sync; for investors, this matters because precise, reliable timing underpins telecommunications, data centers, satellite navigation and high-frequency trading, affecting performance, regulatory compliance and competitive advantage.

augmented reality technical

"The company is integrating emerging technology, including augmented reality and digital twins"

Augmented reality is technology that layers computer-generated images, information or sounds onto your view of the real world through devices like phones, tablets or smart glasses — like seeing navigation arrows or product labels projected onto what you’re looking at. It matters to investors because it creates new ways to sell hardware, software, services and ads, can change customer engagement and recurring revenue models, and carries adoption and privacy risks that affect company value.

digital twins technical

"integrating emerging technology, including augmented reality and digital twins, to accelerate"

Digital twins are virtual replicas of physical objects, systems, or processes that simulate their real-world counterparts in real time. They allow users to monitor, analyze, and predict how the actual entity will behave under different conditions. For investors, digital twins can provide valuable insights into performance and potential risks, helping to make better-informed decisions.

Regional Military Protection technical

"GPS IIIF will feature Regional Military Protection, delivering more than a 60-fold boost"

Regional military protection is the use of armed forces by one or more governments to secure a specific geographic area—such as a group of neighboring countries, trade routes, or critical infrastructure—against threats like armed conflict, piracy, or cross-border attacks. For investors it matters because this security shapes political stability, supply-chain access, insurance costs and the risk of business disruption; think of it as a neighborhood watch that affects whether businesses can operate normally and whether capital flows remain steady.

anti-jamming technical

"more than a 60-fold boost in anti-jamming performance for warfighters"

Techniques and systems designed to prevent or reduce intentional or accidental disruption of radio, satellite, or wireless signals so communications keep working reliably. For investors, anti-jamming matters because it protects the value and usability of products and services that depend on clean signals — like navigation, military systems, or connected devices — and can be a competitive advantage or a regulatory requirement. Think of it like traffic control that keeps cars moving smoothly even when someone tries to block the road.

Global Positioning System technical

"strengthened the Global Positioning System (GPS) constellation to its highest level ever"

A satellite-based system that tells devices their precise location and exact time anywhere on Earth, like a digital compass and clock sent from space. Investors care because GPS underpins navigation, delivery, fleet management, telecommunications timing, and many location-based services; its accuracy and availability affect revenue, costs, reliability and risk for companies that rely on routing, tracking, timing or automated systems.

The final GPS III satellite delivers major upgrades in constellation resilience and accuracy, including a crosslink demonstration payload, as the next-gen GPS IIIF series is in production.

CAPE CANAVERAL, Fla., April 21, 2026 /PRNewswire/ -- Early this morning, Lockheed Martin (NYSE: LMT) and the U.S. Space Force strengthened the Global Positioning System (GPS) constellation to its highest level ever achieved with the launch of GPS III Space Vehicle 10 (SV10), the final satellite in the GPS III series.

SV10 adds essential resiliency and accuracy enhancements to the GPS constellation, including an optical crosslink demonstration payload. With this payload, GPS III SV10 will demonstrate optical communication capabilities that will play a crucial role in the future strength of the constellation. The optical crosslinks allow GPS satellites to be able to directly communicate with each other in space, increasing on-orbit resiliency.

The GPS III SV10 launch marks the fourth consecutive GPS launch on an accelerated schedule, demonstrating Lockheed Martin's rapid delivery of on‑orbit capabilities to warfighters.

GPS III SV10 launched from Cape Canaveral Space Force Station at 2:53 a.m. Eastern time. It secured signal acquisition soon after and is currently managed at Lockheed Martin's Denver Launch & Checkout Operations Center pending formal acceptance into the GPS operational control network.

Why it matters

This spacecraft paves the way for the advanced GPS IIIF generation, which will bring even stronger anti-jamming capabilities for warfighters and improvements for its six billion civilian users. GPS III satellites deliver critical advancements over legacy spacecraft, including three‑times greater accuracy, eight‑times stronger anti‑jamming capability, and secure M‑Code signals for warfighters worldwide.

For military users, these improvements provide dependable positioning, navigation, and timing in contested or hostile environments. For civilian users, GPS III enhances everyday smartphone navigation, speeds up emergency response location, and supplies more precise timing for financial markets and telecommunications networks.

"The final GPS III deployment is an important milestone as we continue strengthening the GPS constellation," said Fang Qian, vice president of GPS at Lockheed Martin. "By launching SV10 into orbit, we're not only adding to the resiliency of today's GPS capabilities – we're opening the door to the next generation of GPS IIIF satellites that will provide greater resiliency and serve as the backbone of the GPS constellation for years to come."

In addition to the crosslink demo, the satellite is also equipped with a demonstration Digital Rubidium Atomic Frequency Standard clock, an advanced atomic clock that will provide reliable and precise time-keeping capabilities.

Preparing for a new era of GPS

With GPS III SV10 in orbit, Lockheed Martin is now focused on production of GPS IIIF satellites. Deploying these next‑generation spacecraft is essential for preserving reliable global coverage, and the IIIF block will add a new suite of capabilities that further harden the constellation's resilience.

Among the upgrades, GPS IIIF will feature Regional Military Protection, delivering more than a 60‑fold boost in anti‑jamming performance for warfighters. This dramatic increase in resistance to hostile interference helps U.S. forces stay ahead of evolving electronic warfare threats.

Lockheed Martin is actively producing GPS IIIF spacecraft at its Denver, Colorado facility. The company is integrating emerging technology, including augmented reality and digital twins, to accelerate GPS satellite production. Lockheed Martin is currently under contract to build 12 GPS IIIF satellites, demonstrating the company's long-term commitment to a resilient and robust navigation infrastructure.

Today, more than 30 GPS satellites operate in orbit, delivering crucial positioning, navigation and timing services to warfighters, civilians and commercial users. Overall, GPS remains the world's most trusted space-based navigation system, serving billions of people.
