|All ships are equipped with basic sensors to allow detection of planets, space debris, allies, and of course enemy ships. The scanner device may be equipped on ships to increase the detection range for planetary structure, combat wreckage, mines, bombs, and other such objects.
This game bases detection ranges on a ships's signature. Larger ships use more power, and generate a larger signature. A ship with a large signature can be detected at a longer range than a ship with a low signature. A signature of zero or below cannot be detected with sensors, though it may still be visible to the naked eye.
ECM devices and anti-sensor bases reduce the signature of all ships in a radius around the device. Nebulae have the same type of effect, reducing the signature of everything inside them. ECCM devices and sensor bases raise the signature of nearby ships.
In addition to increasing the object detection range, scanners also increase the signature of the ship which is using it. Beacons can be placed on ships to boost their signature. Each beacon lasts for a limited time, and adds 20 to the target's signature while active.
