Celestial Navigation is the art and science of finding your way by the sun‚ moon‚ stars‚ and planets‚ and‚ in one form or another‚ is one of the oldest practices in human history. Celestial navigation‚ also known as astronavigation‚ is a position fixing technique that has evolved over several thousand years to help sailors cross oceans without having to rely on estimated calculations‚ or dead reckoning‚ to know their position. Celestial navigation uses "sights‚" or angular measurements taken between

them from getting lost. This was done by both land dwellers and early seafarers that would follow the coastline to reach their destination. If a boat ever lost sight of land‚ all would not be lost because the sailors could rely on watching the flight of the birds and the motion of the waves. The stars in the sky gave paths that could be followed by experienced navigators. The experienced navigators of many different cultures proved that celestial navigation was possible without the need for instrumentation

Personal navigation devices have become so popular because some people get tired of getting lost while driving‚ are not proficient at reading road maps‚ don’t always have a navigating passenger in their car that can tell them when they have to turn‚ and don’t have access to a plethora of needed maps in their car. Personal navigation devices are an answer to these problems. What technologies are required to facilitate the success of PNDs

Hyperbolic navigation Hyperbolic navigation refers to a class of radio navigation systems based on the difference in timing between the reception of two signals‚ without reference to a common clock. This timing reveals the difference in distance from the receiver to the two stations. Plotting all of the potential locations of the receiver for the measured delay produces a series of hyperbolic lines on a chart. Taking two such measurements and looking for the intersections of the hyperbolic lines

Speaker’s notes Contours on the map are the brown lines drawn on a map connecting points of equal height above sea level. They are labelled with the height and with the topes of the figures uphill. A contour labelled 500 is 500m above sea level‚ and every place on that contour is precisely 500m above sea level. On a 1: 25‚ 000 map‚ they are usually 10m apart. If contours are very close together that means the hill is steep. However‚ is they are wide apart‚ it has a gentle gradient. When
