Is the sun's path through the sky predictable?
Entirely predictable. It's so predictable that we can measure the position of the Sun in the sky to determine our position, a method we call "celestial navigation".
What gives Hubble its excellent clarity its size or its position in space?
Above all the position in space, with the absence of a disturbing atmosphere, is the prime factor of the excellent pictures. This is also the reason why it was built at all. Of course, the larger the instrument the better for observations.
What is the function of the navigation satillite?
Satellite Navigation The U.S. govt launched satellites that triangulate any spot on the globe and give your location if you have the device that receives their signal. For further clarification, GPS receiver units time a signal sent from a satellite and through the use of extremely accurate clocks, calculate the time it took for the signal to reach the receiver from the satellite. Knowing the speed that these signals travel allows the receiver to calculate a distance from the satellite which results in a line of position (LOP). Obtaining a minimum of three of these LOPs allows the receiver to accurately determine the receiver's position on the face of the earth. Having a fourth LOP will also allow the determination of the elevation, or height, of the receiver.
What is a star diagram in celestial navigation?
a star diagram is a circle on which we plot the location of stars the circle represents the sky above and it is divided into 4 quadrants while knowing the northerly direction we plot the stars with respect to its location from true north and we tabulate its declination in a separate column since location of stars for a particular time from a particular geographical position is predictable so we match it and obtain own position in terms of latitude and longitude
What tool or instrument would be useful if you orienteering?
An hand compass, or an analogue wrist watch. If you know how to read an analogue wrist watch m you can find the South Direction, by using the fingersw against the Sun's position. NB THis is Boy Scout stuff!!!!!
What navigation instrument is used to determine a ship's position at sea?
Astrolabe.
What are magnetic compasses?
It is the oldest instrument for navigation and has been a vital tool for navigators at sea for centuries. The compass allows ships to steer a selected course. By taking bearings of visible objects with a compass, the navigator is also able to fix a ship's position on a chart.
What explorers used a compass?
Compasses have been used for a long time, mainly by seafarers & explorers. It is the oldest navigation instrument, and it has been a very important tool for navigation at sea for centuries. It has been used since the middle ages, allowing ships to sail the chosen course. Also, by taking bearings with a compass, people could find their position on a chart.
What scientific discoveries improved navigation and overseas exploration?
An astrolobe which is an instrument that measured the position of the stars , and the magnetic compass helped determine the ships approximate location.
What is sailing by the stars?
Astral navigation. By using a sextant (instrument used to measure the altitude of a celestial object) a clock and logarithms you can work out your position on the earth's surface hence 'sailing by the stars'
What is a system of navigation in which a navigator finds position?
Triangulation.
How do you use sextant in a sentence?
A sextant is a navigational instrument that sights upon the stars to determine a ship's position. This instrument was crucial to naval navigation until global positioning became a reality in the late 20th century. "Henry the Navigator prized his sextant while on his journeys to the New World." "The ship's position is determined by the use of the ship's navigator using a sextant."
What is the science of art of determining the position of a ship or plane?
Navigation
What is the science of getting ships from place place including the determining of position course and distance traveled?
Marine navigation.
What is the meaning of coastal navigation?
Coastal navigation is transport by sea or inland waterways. The coast is rarely out of sight and so position can be confirmed by land features and navigation marks, such as light houses and buoyage.
What is definition of a navigation?
A method of determining ones position by geometry and astronomy
What is the science or art of determining the position of a ship or plane and guiding it to its destination?
Navigation
