Autonomous navigation

Definition

Autonomous navigation refers to the ability of spacecraft or rovers to navigate and make decisions independently without direct human intervention. This technology is essential for planetary exploration, enabling missions to operate efficiently in remote environments where real-time communication with Earth is limited or delayed. It allows vehicles to analyze their surroundings, plan routes, and adapt to unexpected challenges, ultimately enhancing the success and safety of current and future missions.
