Sensors

[lnielsen]

You need to have sensors in each system you are concerned with. One of the best ways to do this is to deploy a single "sensor bouy" in each system. You might want to have a combination of sensors (gravity, optic, ...) to cover a wider range but use only the highest level of each. The emeny ship might have good gravity cloaking but poor optical any you will still see him.
One sensor bouy in the system will let all your forces see him.
