Time and Navigation - Apollo Sextant and Scanning Telescope

Navigating in space: to determine position in space, an Apollo astronaut located a specific star using a single-power, wide-field telescope and then took a fix using a sextant. While this instrument does not look like a traditional sextant, the basic procedure is descended from centuries-old methods used by navigators at sea and in the air.

Time and Navigation - Bond Chronometer

This timekeeper was the first American-made marine timekeeper taken to sea. William Cranch Bond, a 23-year-old Boston clockmaker, crafted it during the War of 1812.

This artifact is in the National Museum of American History's collection. It will go on display in the Time and Navigation exhibition, scheduled to open at the National Air and Space Museum in 2013.

Time and Navigation - Bygrave Position-Line Slide Rule

Celestial navigation requires complicated computations. Performing these calculations in cramped open cockpits with low temperatures and wind speeds of over 160 kilometers (100 miles) per hour was part of what made navigation difficult in the early years of aviation. Thankfully, Capt. L. C. Bygrave developed this handy slide rule shortly after World War I.

Wiley Post’s Winnie Mae circled the globe two times, shattering previous records. The first time was in 1931 with Weems associate Harold Gatty as lead navigator. The second was a solo flight in 1933 assisted by “Mechanical Mike,” one of the world’s first practical autopilots.

Time and Navigation - Longines Sidereal Second-Setting watch

Before 1927, watches used with sextants for celestial sightings could only be set to the minute. A watch error of 30 seconds caused a navigational error of up to 12 kilometers (7 miles). In 1927, P. V. H. Weems devised a watch with an adjustable second hand that could be set using radio time signals. This was one of his personal navigation watches.

Time and Navigation - Ramsden Sextant

Navigating at sea: this sextant was one of the navigation tools invented in the 18th century by British mathematical instrument makers that permitted mariners to find their position much better than ever before. The sextant became the most essential instrument for celestial navigation, used to find the angle of a celestial body above the horizon.

This autonomous vehicle, named Stanley, was developed by the Stanford Racing Team. Stanley is a 2005 Volkswagen Touareg modified to navigate without remote control and without a human driver in the seat.
