Lockheed Martin Integrates GPS and Quantum Navigation

Lockheed Martin is advancing resilient Position, Navigation and Timing (PNT) capabilities by integrating its modernized GPS satellite technology with next-generation quantum navigation sensors. The defense contractor detailed the strategic integration in a feature published on June 24, 2026, highlighting a system designed to ensure unbroken positioning for military operators in contested or GPS-denied environments.

Traditional GPS signals can be disrupted by physical structures, severe space weather, or adversarial jamming. To counter these vulnerabilities, Lockheed Martin is pairing satellite data with quantum sensors that operate independently of external signals by relying entirely on internal measurements. This combination allows the GPS network to establish a reliable baseline while quantum technology continuously refines the positioning data.

Modernizing the GPS constellation

The foundation of this hybrid navigation approach relies on the ongoing modernization of the United States military satellite network. Lockheed Martin produces the GPS III and upcoming GPS IIIF satellites, which introduce significant upgrades over legacy spacecraft to maintain signal integrity in hostile electronic environments.

According to the company, GPS III satellites deliver up to eight times the anti-jamming power of previous generations. The subsequent GPS IIIF satellites will increase this anti-jamming capability up to 63 times through Regional Military Protection (RMP) beam-focusing techniques. Beyond military applications, these modernized satellites incorporate specialized emergency signal processing for Civilian Search & Rescue operations and a Nuclear Detection System to monitor global treaty compliance.

Transitioning quantum technology to the field

To complement the satellite network, Lockheed Martin is accelerating the deployment of quantum technology from laboratory environments to operational hardware. This effort is supported by multiple United States Department of Defense (DoD) initiatives aimed at fielding functional prototypes.

On March 12, 2025, the Defense Innovation Unit (DIU) awarded a contract to Lockheed Martin, alongside quantum technology companies Q-CTRL and AOSense, to prototype a Quantum-enabled Inertial Navigation System (QuINS). The QuINS platform utilizes matter-wave interferometry to calculate a vehicle’s position, speed, and orientation based entirely on internal measurements, rendering it immune to external signal jamming.

Development continued when Q-CTRL announced its selection for the Defense Advanced Research Projects Agency (DARPA) Robust Quantum Sensors (RoQS) program on August 27, 2025, with Lockheed Martin serving as a subcontractor. At the 2026 Joint Navigation Conference, the partner companies presented technical progress on Phase 1 of the QuINS program, which involves testing a purpose-built sensor equipped with a laser and electronics package optimized for dynamic environments.

Lockheed Martin emphasized the necessity of this dual approach in its June 24 publication.

“GPS determines the initial ‘big picture’ position, providing the range of known locations with civilian global Earth coverage. Quantum sensing refines that picture, delivering pinpoint accuracy in conjunction with GPS signals, even in contested environments.”

AirPro News analysis

The integration of quantum inertial navigation with modernized GPS represents a critical shift in aerospace engineering, particularly for military aviation and unmanned aerial systems operating in contested airspace. As electronic warfare and GPS spoofing become standard adversarial tactics, reliance on external radio frequency signals is a known vulnerability. By moving quantum sensors out of the laboratory and into dynamic flight environments, we are observing the foundational steps toward fully autonomous, unjammable navigation systems. While the current focus remains on defense applications, the successful miniaturization and ruggedization of matter-wave interferometry packages will likely influence future commercial aviation navigation standards.
