The reverse is also true, whilst rowing across the Atlantic, the very top of a mountain range 400m high could be seen on your horizon at a distance of 71.4 km assuming the air was clear enough. Find out what your monthly payment will be for your loan or line of credit. Sitting in a hotel room 10m above sea level a boat on the horizon will be 11.3km away. The horizontal coordinate system, also known as the Alt/Az system, is a method for describing the exact position of objects in the sky, such as planets, the Sun, or the Moon.
HORIZON LINE CALCULATOR PLUS
Using Pythagoras's theorem we can calculate the distance from the observer to the horizon (OH) knowing CH is the earth's radius (r) and CO is the earth's radius (r) plus observer's height (v) above sea level. However, you can rapidly calculate the curvature of the Earth by using this helpful Curvature of Earth Calculator. The calculators also calculates the radio. Earth Curvature Calculator: Calculating your distance to the horizon, as well as the height of the target buried behind the horizon of an Earth curvature, is a difficult task.
A triangle is formed with the centre of the earth (C) as one point, the horizon point (H) is a right angle and the observer (O) the third corner. This line of sight calculator calculates how far the horizon is from an antenna placed at a particular height.
It also assumes the horizon you are looking at is at sea level. The distance to that horizon depends only on the height of the observer. This calculation should be taken as a guide only as it assumes the earth is a perfect ball 6378137 metres radius. spherical world can only see a limited distance - to a line we call the horizon. Some theory is placed below the calculator. Thats 500,000 meters, or the second-to-last line of the table.
Distance to the Horizon Calculator Observation Height in Metres in FeetĮnter the Height, set for Metres / Feet then click the Calculate button. The calculator below computes the prospect distance from height at observer and line of sight distance between two observers. If you want to know the distance to the horizon, first calculate your height of eye. The altitude is how many degrees above (if positive) or below (if negative) the horizon Point B is when seen from Point A.
