Geopotential altitude Solution

Follow our step by step solution on how to calculate Geopotential altitude?

FIRST Step Consider the formula

h = [Earth-R] \cdot \frac{h G}{[Earth-R] + h G}

Next Step Substitute values of Variables

∴

h = [Earth-R] \cdot \frac{28991m}{[Earth-R] + 28991m}

Next Step Substitute values of Constants

∴

h = 6371.0088km \cdot \frac{28991m}{6371.0088km + 28991m}

Next Step Prepare to Evaluate

∴

h = 6371.0088 \cdot \frac{28991}{6371.0088 + 28991}

Next Step Evaluate

∴

h = 28859.6752957399m

LAST Step Rounding Answer

∴

h = 28859.6753m

How to Evaluate Geopotential altitude?

Geopotential altitude evaluator uses Geopotential altitude = [Earth-R]*Geometric Altitude/([Earth-R]+Geometric Altitude) to evaluate the Geopotential altitude, Geopotential Altitude is a measure of the altitude of an object or point on the Earth's surface, adjusted for the Earth's slightly ellipsoidal shape, providing a more accurate representation of the altitude above the Earth's geoid, which is the hypothetical surface that coincides with the Earth's mean sea level. Geopotential altitude is denoted by h symbol.

FAQs on Geopotential altitude

What is the formula to find Geopotential altitude?

The formula of Geopotential altitude is expressed as Geopotential altitude = [Earth-R]*Geometric Altitude/([Earth-R]+Geometric Altitude). Here is an example- 28859.68 = [Earth-R]*28991/([Earth-R]+28991).

How to calculate Geopotential altitude?

With Geometric Altitude (h_G) we can find Geopotential altitude using the formula - Geopotential altitude = [Earth-R]*Geometric Altitude/([Earth-R]+Geometric Altitude). This formula also uses Earth mean radius, Earth mean radius constant(s).

Can the Geopotential altitude be negative?

No, the Geopotential altitude, measured in Length cannot be negative.

Which unit is used to measure Geopotential altitude?

Geopotential altitude is usually measured using the Meter[m] for Length. Millimeter[m], Kilometer[m], Decimeter[m] are the few other units in which Geopotential altitude can be measured.
