Special Topics - GPS (65 of 100) What is Reference Ellipsoid

[@Nerd3927]

This is the GRS80 reference ellipsoid. Many local datums use an older one, like the Bessel 1841 for the Dutch RijksDriehoekstelsel.

[@MichelvanBiezen]

Yes indeed. Thank you for this very interesting comment. 🙂

nice lectures professor

[@MichelvanBiezen]

Thank you. Glad you enjoyed it. 🙂

Where this (2a+b)/3 came from? I never saw it before... I thought that average was (a+b)/2 Why it can't find this representative R equaling the volume of a sphere and an ellipsoid? (We do that in irregular particles, like in bulk catalyst description) 4πabc/3 = 4πr³/3

[@MichelvanBiezen]

With an ellipse, the slope changes and the change of the slope is not a constant. To have a better approximation of the average orbital radius when the shape is an ellipse, it is better to use (2a+b)/3 (We are not trying to find the average value of 2 numbers a and b)

Thanks professor

[@MichelvanBiezen]

You are welcome 🙂

how can I find the rest of this lecture

[@MichelvanBiezen]

We are still working on them. We publish one new video on GPS every Thursday.

ellipsoid makes me think of a mexican food product that can be rebranded to get cohesion in west coast. like pinata. theyre called huaraches and it is a dense corn paste that provides calcium sodium and carbs.

[@MichelvanBiezen]

Never saw that connection !
