When considering that a full calendar year has 8,760 hours and a commercial airliner can be in service for about 30 years (or around 165,000 flying hours), then achieving a continuous performance milestone of 65 million hours is truly out of this world - exactly where Northrop Grumman navigation technology has been operating for decades. In 2022, Northrop Grumman's hemispherical resonator gyros (HRGs), sensors known for their unmatched reliability on commercial, government and civil space missions, successfully performed for more than 65 million hours in space without a single mission failure. More than 200 Northrop Grumman HRG navigation units are operating in spacecraft orbiting the Earth and exploring the outer reaches of the solar system. The company's HRG technology has contributed to the success of spacecraft and satellites for nearly 30 years. One reason for the HRG's success is that it's inherently radiation hardened - meaning its electronic components are shielded against radiation exposure, extreme temperatures and aging effects.
The SSIRU and Seeing Into Deep Space "We have an exceptional proven record of navigational performance for strategic and innovative deep space applications," said Ryan Arrington, director of space and strategic programs, navigation, targeting and survivability, Northrop Grumman. "Our development teams' decades of successful HRG and SSIRU operational achievements are advancing future navigation capabilities by building next-generation gyroscopes, accelerometers and systems."
Visiting a Planet? Pack a SSIRU NASA's Cassini mission to Saturn, launched back in 1997, also relied on SSIRU navigation to explore the ringed planet and several of its moons, including flybys of Titan and Enceladus. After traveling for six years and about 2.2 billion miles through the solar system, Cassini finally arrived in the Saturn system in June 2004.
Future SSIRU Space Missions The company's SSIRU will also be carried aboard NASA's Nancy Grace Roman Space Telescope, which will observe explosions caused by the collisions of dense, massive stars. The telescope is set to launch in May 2027.
New HRG, SSIRU Navigation Technology "As industry leaders in HRG and SSIRU technology, we are well-positioned to meet the current and future space navigation needs of satellite and spacecraft customers," said Larry Hershman, program manager, navigation, targeting and survivability, Northrop Grumman. "By focusing on high accuracy, precision and durability combined with size, weight and power specifications, Northrop Grumman navigation devices have enabled journeys covering billions of miles throughout the solar system and beyond." Whether they are guiding spacecraft across the vast extensions of the galaxy or stabilizing on-board cameras to capture jaw-dropping images of stars, planets and worlds that are light years from Earth, Northrop Grumman's HRG and SSIRU space navigation technology keeps setting new performance standards on a continuing mission to define possible.
AFRL awards contract for pioneering spacecraft in region of Moon Kirtland AFB NM (SPX) Nov 15, 2022 The Air Force Research Laboratory has awarded a $72 million contract to Advanced Space LLC to demonstrate space situational awareness, object detection and tracking in the region of the Moon, supporting a resurgence of interest in lunar exploration and development across civil, commercial and international space agencies. AFRL's Space Vehicles Directorate awarded the contract to support the lab's Oracle spacecraft program, previously called the Cislunar Highway Patrol System, or CHPS. The project ... read more
