A person trained in astronavigation who determines spacecraft or vehicle position and direction using celestial observations and calculations.
From 'astronavigation' plus '-or' to denote the person performing the task. The term became formalized with aviation and astronautics in the 20th century.
Astronavigators were essential crew members on early space missions, but GPS and computer systems have made the role nearly obsolete—yet spacecraft heading to Mars still rely on these principles!
The term historically referred to male pilots and navigators; female astronauts and navigation specialists were systematically excluded from space programs until the 1960s-80s.
Use 'astronavigation specialist' or 'space navigator' to encompass all genders, or specify role without gendered agent noun.
