What is the Jervis Autonomy Module (JAM)?The Jervis Autonomy Module (JAM) is RSA’s proprietary AI-based navigation system. It enables spacecraft to autonomously navigate and make decisions in GPS-denied or communication-limited environments—ideal for deep space, lunar, and defense missions.
-
What is optical navigation, and why does it matter?Optical navigation is a method of spacecraft guidance that uses visual cues—like stars, moons, and asteroids—instead of relying solely on radio signals or GPS. It’s essential for autonomous space travel, especially beyond Earth orbit. RSA is pioneering autonomous optical navigation systems to support future lunar and interplanetary missions.
-
Does RSA work with artificial intelligence?Yes. RSA integrates AI and machine learning into many of its systems, including spacecraft autonomy, sensor data analysis, object tracking, and decision-making algorithms. AI plays a key role in enhancing speed, accuracy, and resilience in space operations.
