Before GPS, how did aircraft navigate? One important technique was celestial navigation: navigating from the positions of the stars, planets, or the sun. While celestial navigation is accurate, cannot be jammed, and doesn’t require any broadcast infrastructure, it is a difficult and time-consuming process to perform manually.
