Interstellar Navigation

Interstellar navigation involves precisely determining a spacecraft’s position and course as it travels between stars. It relies on techniques like stellar navigation—using telescopes to identify and track distant stars—and radio signals from Earth for timing and course adjustments. Advanced methods may include measuring shifts in star positions caused by motion (parallax) or analyzing the spacecraft’s velocity through Doppler shifts. These techniques ensure accurate course plotting over vast distances, enabling spacecraft to reach their destinations efficiently despite the immense scale and the challenges posed by deep space.
