NASA's Vision For Space Navigation: GPS for the Moon and Beyond

NASA is developing advanced space navigation systems for lunar and Martian missions, aiming to replicate GPS functionality where it doesn't exist. The primary goal is a lunar GPS system with satellites orbiting the Moon, providing positioning data for spacecraft, rovers, and bases. This system will rely on highly accurate atomic clocks for precise timing. NASA is also exploring radiometric tracking and using existing GPS signals. These advancements are crucial for autonomous navigation and long-term human presence in space, supporting sustainable space exploration throughout the solar system.
