Expand "geocentric" to
/the center of the Earth; geocentric/
(LA, for example, defines 地心 as 地球的中心點, which is a *point*, unlike Earth's core)

地心坐标系 geocentric coordinate system.
地心轨道 geocentric orbit.

("geocentric" on its own is ambiguous - it can mean "having or relating to the earth as center", contrasted with "heliocentric")

* * *

"earth's core" is 地核, and my sense is that 地心 is a looser, less technical term.
Wikipedia redirects 地心 to 地核, but that does not necessarily mean the two are synonymous.

Examples for "Earth's interior":

沧海桑田,六百万年前菲律宾海板块首先撞出东北部花莲、宜兰,随着菲律宾板块往地心俯冲,挤压力量逐渐南移。

地心是热的,不断变动,

毛河光利用钻石做「高压砧」,以等同于地心的超高压力(360万大气压)加诸其上,藉此来观察高压世界里的各种物质变化。

杜思妥也夫斯基特有的一种幽暗气息,简直像是地心透出微光一样。
Diff:
- 地心 地心 [di4 xin1] /the earth's core/geocentric/
+ 地心 地心 [[di4xin1]] /the center of the Earth; (attributive) geocentric/the Earth's interior/
