No. It's strictly a system for locating and describing points on the surface of the Earth.
Nothing about the latitude/longitude system is defined in terms of anything in the sky.
All that's needed in order to lay out the whole system is the Earth's poles and the Royal
Observatory at Greenwich.
Earth's reference system is based on latitude and longitude, with the equator serving as the reference for latitude and the Prime Meridian as the reference for longitude. This system allows for precise location determination on Earth's surface using coordinates.
Latitude and longitude are written in degrees to measure angles. The Earth is divided into 360 degrees of longitude and 180 degrees of latitude, with 0 degrees at the equator and the Prime Meridian, respectively. This system allows for precise and universal location coordinates across the globe.
Meridians of constant longitude cross parallels of constant latitude. Parallels of constant latitude cross meridians of constant longitude. At each intersection of a meridian and a parallel, the lines are perpendicular (form 90° angles).
GPS receivers do not 'use' elevation for anything. They use the signals from several satellites simultaneously to calculate the latitude, longitude, and elevation of the receiver's location. It takes a minimum of three satellites to calculate the latitude and longitude, a minimum of four satellites to calculate the latitude, longitude, and elevation, if more satellites can be found the latitude, longitude, and elevation calculations can be refined more accurately.
Earth's coordinate system of latitude and longitude is determined primarily by the Earth's shape and rotation. Latitude lines run parallel to the equator, measuring the distance north or south, while longitude lines converge at the poles, measuring the distance east or west from the Prime Meridian. The Earth's spherical shape influences how these lines are spaced and defined, while its rotation affects the time zones associated with longitude. Together, these factors create a grid system that allows for precise location identification on the planet's surface.

No. Latitude and longitude are angles, and angles have no physical units. So the numbers are the same regardless of what system of units you like.

Longitude and Latitude
Earth's reference system is based on latitude and longitude, with the equator serving as the reference for latitude and the Prime Meridian as the reference for longitude. This system allows for precise location determination on Earth's surface using coordinates.
On a graph, 'x' and 'y' are marked and measured in length or distance units. Latitude and longitude are marked and measured in angles.
Latitude and longitude are written in degrees to measure angles. The Earth is divided into 360 degrees of longitude and 180 degrees of latitude, with 0 degrees at the equator and the Prime Meridian, respectively. This system allows for precise and universal location coordinates across the globe.
Global Positioning System
The imaginary lines that form the earths grid system are called latitude and longitude lines. Latitude lines go horizontally from east to west, where longitude lines go vertical from north to south.
Latitude and longitude
Meridians of constant longitude cross parallels of constant latitude. Parallels of constant latitude cross meridians of constant longitude. At each intersection of a meridian and a parallel, the lines are perpendicular (form 90° angles).
