One of the mysteries of the English language finally explained.
The process of calculating one's position, especially at sea, by estimating the direction and distance traveled rather than by using landmarks, astronomical observations, or electronic navigation methods.
- ‘Back in 1927, Lindbergh proved that a combination of dead reckoning and pilotage can work well, even over a 3,610-mile, 331 2-hour flight.’
- ‘When human mariners and lunar astronauts navigated by dead reckoning they used charts, tables, various measuring instruments, and a considerable amount of mathematics.’
- ‘Steady course and speed or continuous monitoring of their changes is required for effective dead reckoning.’
- ‘Considering the weather conditions, dead reckoning or entering accurate data on the GPS was not a possibility.’
- ‘They had been in clouds since the beginning, navigating only by dead reckoning.’
- ‘Even if you choose to find your way by dead reckoning, the rear-view mirror has a little LED display to tell you which point of the compass you are heading towards.’
- ‘We fitted the trucks with air wheels - balloon tires, we would say now - and kept going, navigating like mariners, by sextant and compass and dead reckoning.’
- ‘I had been going by dead reckoning, traveling up the incline, letting the slope of the incline guide me.’
- ‘Due to this appalling weather the convoy had to rely on dead reckoning for navigation.’
- ‘There is no corresponding southern pole star, so dead reckoning became the primary navigating process.’
- ‘For centuries, the only way to navigate was to look at the position of the sun and stars and use dead reckoning.’
- ‘After I crossed the first two rivers my dead reckoning told me it was time to take the turn south, but the high mountain checkpoint was not in sight.’
- ‘It was the Greeks who pioneered modern methods of navigating by calculation rather than by dead reckoning.’
- ‘Sometimes he takes one route, and sometimes another, just as his fancy inclines him, he pays no attention to the compass, but sails by dead reckoning of his own devising.’
- ‘Christopher Columbus used dead reckoning for his voyages across the Atlantic Ocean.’
- ‘In dead reckoning you estimate distance traveled along a given heading as a function of velocity and elapsed time.’
- ‘Since medieval times, mariners have employed dead reckoning to navigate their vessels.’
- ‘At first, crews had to rely on dead reckoning - estimating position by speed, flying time and compass.’
- ‘The pure navigational techniques of celestial and dead reckoning should have been superseded at this time by pilotage.’
- ‘I decided to refigure all my dead reckoning and try to at least get some general idea of where I should be.’
