The 62 pages that link to Dead reckoning, each with the reason it gives.

• Joshua SlocumRelated: Before reliable satellite navigation, this method helped Slocum estimate Spray’s position at sea.

• MazeRelated: Remembering turns and distances can help preserve orientation inside a maze.

• Sven HedinRelated: In poorly mapped deserts, Hedin's parties often had to estimate their position between observations.

• Valery ChkalovRelated: Over remote northern terrain, crews relied on estimated position when landmarks and radio aids were scarce.

• Charles Kingsford SmithRelated: Crews used it when ocean crossings put landmarks and reliable fixes out of reach.

• East (direction)Related: An eastward course is one input for estimating a vessel’s or vehicle’s position.

• Jerrie MockRelated: Over remote stretches, Mock had to navigate without continuous ground-based guidance.

• Luís Vaz de TorresRelated: Before reliable longitude, estimates like these helped navigators track progress across open water.

• Phantom islandRelated: Small errors in estimated position could make an island appear where none existed.

• Satellite navigation deviceRelated: Some devices use it to continue estimating location between satellite fixes.

• Surveyor's wheelRelated: Wheel readings can estimate distance along a route, though they do not establish position by themselves.

• Voyages of Christopher ColumbusRelated: Columbus's crews relied on this method to estimate their position during ocean crossings.
