A smaller, lighter and more cost-effective design for every space mission
Northrop Grumman Corporation is introducing the LR-450, a compact, lightweight positioning and navigation system built for a variety of space missions. The LR-450 delivers continuous, precise spacecraft tracking and orientation even when satellite signals are unavailable.
The new system is now available worldwide for purchase and integration across space platforms.
Ryan Arrington, vice president, navigation and cockpit systems, Northrop Grumman: "Northrop Grumman's LR-450 sets a new benchmark for dependable, cost-effective space navigation solutions. By integrating our proven sensor technology with a compact, rugged design featuring the innovative mHRG system, the LR-450 delivers unmatched precision, reliability and zero-maintenance operation. This means operators can confidently tackle a wide range of missions, from low Earth orbit to planetary exploration, all while benefiting from exceptional affordability and outstanding value."
Northrop Grumman leads the industry in positioning, navigation and timing solutions for demanding environments – from underwater to outer space. The LR-450 leverages advanced manufacturing techniques to ensure spacecraft maintain course and orientation without external dependencies.
The core of the LR-450 system is its milli-Hemispherical Resonating Gyroscopes, which are scaled-down versions of the high-performance HRGs used in Northrop Grumman's Spacecraft Stellar Inertial Reference Unit (SSIRU). These sensors provide high reliability and precision, which are critical for spacecraft navigation.
Northrop Grumman's scalable, cost-effective designs allow the LR-450 to support a variety of missions, including deep space probes, planetary landers, and satellites in Earth orbit. With compact size and low power requirements, the LR-450 offers engineering teams greater flexibility to meet specific spacecraft designs and mission objectives.
