Northrop Grumman has unveiled the new compact LR-450 navigation and positioning system designed for spacecraft. This device is developed for use in various missions, ranging from Earth-orbiting satellites to interplanetary stations and landing modules. This is reported by Ixbt.com reports .
The main advantage of the LR-450 system is its ability to continuously determine the position and orientation of a spacecraft even in the absence of external satellite signals. The system uses inertial navigation based on miniature gyroscopes called mHRG (milli-Hemispherical Resonating Gyroscopes). This technology allows for precise measurement of movement and rotation without the need for external communication.
The new model is based on Northrop Grumman's long-standing HRG gyroscope technology. Systems of this type have accumulated over 70 million hours of operation in space and were used, in particular, on the James Webb Space Telescope. The LR-450 is a more compact version of the sensors used in previous SSIRU systems.
The small size and light weight of the system make it easy to integrate into various spacecraft, allowing for more space and weight savings for the payload. Additionally, the device consumes low power and is designed to operate continuously for millions of hours without maintenance.
Ryan Arrington, a representative of Northrop Grumman, noted that the LR-450 combines high precision, reliability, and affordability. Currently, the system is open for orders for installation on commercial and scientific space platforms worldwide.
