High Earth orbit

[1] In this article, the non-standard abbreviation of HEO is used for high Earth orbit.

The ability to place satellites in HEO has allowed scientists to make groundbreaking discoveries in astronomy and Earth science, while also enabling global communication and navigation systems.

[3] Satellites in High Earth orbits are primarily used for communication, navigation, scientific research, and military applications.

[4] One of the main benefits of HEO is that it provides a nearly unobstructed view of the Earth and deep space.

In addition, satellites in HEO can provide a continuous coverage of the Earth's surface, making it very useful for communication and navigation purposes.

As a result, spacecraft in HEO require specialized equipment and shielding to protect them from radiation.
