Orbital buildings provide a constant, reliable service to your empire. Few are affected by specialist assignments or the planet where they are built, so will always work the same no matter what happens on the ground. Orbital buildings are however more vulnerable to attack, and provide easier targets to enemies than ground based buildings.

There few restrictions when building Jump Gates:

- Only one Jump Gate can be built in a system (whoever the owner would be)
- Jump Gate can be built if no other operating Jump Gate exists in 400 LY range.
