horizontal (altitude, azimuth) to geocentric (longitude, latitude)
Please provide values below to convert horizontal (altitude, azimuth) to geocentric (longitude, latitude), or change ↔.
horizontal (altitude, azimuth)
Definition: A local coordinate system used in astronomy, with the observer's horizon as the reference plane, and positions defined by altitude (angle above the horizon) and azimuth (angle measured from the North).
Historyandorigin: Used for centuries by navigators and astronomers, the horizontal system is based on the observer's location on Earth.
CurrentUse: Commonly used in telescopes, and for ground-based astronomical observations and navigation.
funfact: The horizontal coordinate system is easy to use for local observations, as it is tied directly to the observer's horizon!
geocentric (longitude, latitude)
Definition: A coordinate system based on the center of the Earth as the reference point, measuring positions of objects relative to the Earth’s surface and equator.
Historyandorigin: Historically used by ancient astronomers, it was the standard model for the universe until the heliocentric model was adopted.
CurrentUse: While largely replaced by other models, it is still used for satellite navigation, GPS, and local astronomical observations.
funfact: The geocentric system is tied to Earth's surface, making it practical for terrestrial measurements and navigation!

How to Convert horizontal (altitude, azimuth) to geocentric (longitude, latitude)
1 horizontal (altitude, azimuth) = 1 geocentric (longitude, latitude)
1 geocentric (longitude, latitude) = 1 horizontal (altitude, azimuth)
we use cross multiplication method
horizontal (altitude, azimuth) → geocentric (longitude, latitude)
1 → 1
1.5 → ?( suppose x)
=>1.5*1=1*x
by simplifying
x=1.5
