When a [[Warp_Drive|warp drive]] is engaged in a [[Solar_System|solar system]], the system will gain a warp signature that can be detected by [[cities]] and [[spacecraft]] with the correct equipment and technology.
[[Solar_System|Solar system]]s with high [[electricity]] consumption will send out emissions that can be detected by [[cities]] in other solar systems. The strength of the emissions is affected by the total amount of electricity used by all cities and [[spacecraft]] in the solar system.
A city's chance of detecting emissions from other solar systems depends on the city's deep space sensor range defined by the [[radar]] and the strength of the emissions.
==Warp Signature Strength==
The warp signature is a measure of the accumulated [[Warp_Drive|warp drive]] engaged in the [[Solar_System|Solar system]]. The strength of the signature depends on the warp factor that was engaged.
==Emissions Output==
[[Airport_Terminal|Airport terminal]]s and [[Military_Airport_Terminal|military airport terminal]]s account for one warp drive engage per hour, at the maximum warp factor available to the empire. Warp technology of an empire is based on the highest [[patent]] they know for making a [[Warp_FTL_Drive_Module|warp FTL drive module]].
[[Solar_System|Solar system]]s produce emissions when [[cities]] and [[spacecraft]] consume [[electricity]]. The higher the solar system's total power consumption is, the higher the emission strength and thus the further away the solar system can be detected from.
[[Harsh_Environment_City|Underwater cities]] emit 1/10th the city's normal emission output thanks to the insulation caused by the water.
For example, if a ship engages warp at factor 4 and another ship engages warp at factor 2, and the system contains two cities with airports owned by empires with warp 2 technology, the solar system will emit an accumulated warp signature of 10.
==Emissions Detection Range==
Warp signatures reach about one [[sector]] in radius per accumulated warp factor. The example signal would reach about 10 sectors. Beyond that it is too weak to be detectable.
The maximum range of emission detection depends on the furthest deep space sensor range of any [[Airport_Radar|airport radar]] or [[Military_Radar|military radar]].
Any [[Solar_System|solar system]] outside this range cannot be detected, no matter how high the emission output of the solar system is.
==Warp Signature Detection==
Warp signatures can be detected by [[cities]] with a [[radar]] of an empire with a [[patent]] for any [[Warp_FTL_Drive_Module|warp FTL drive module]] and [[spacecraft]] with [[sensor]]s and [[Warp_Drive|warp drive]]s. Their warp signature detection range is reported on their [[Spacecraft_Blueprint|spacecraft blueprint]] specifications as ''warp signature detection range''.
===Spacecraft Sensors===
Actual maximum detection range is the lesser of the two values: the range the signal can reach and the detection range of the radar or sensors.
A [[spacecraft]] with [[sensor]] will also detect emissions from nearby solar systems, but the spacecraft will have to remain in the same solar system for about 6 hours for all possible emissions to be detected.
==Light Lag==
The emissions are affected by light lag, meaning that they travel at [[lightspeed]]. The further away the emission source is, the longer it takes for the emissions to be visible by the detector.
The average light lag for emissions is just a few hours.

The light blue glow indicates detected warp signatures.
When a warp drive is engaged in a solar system, the system will gain a warp signature that can be detected by cities and spacecraft with the correct equipment and technology.
Warp Signature Strength
The warp signature is a measure of the accumulated warp drive engaged in the Solar system. The strength of the signature depends on the warp factor that was engaged.
For example, if a ship engages warp at factor 4 and another ship engages warp at factor 2, and the system contains two cities with airports owned by empires with warp 2 technology, the solar system will emit an accumulated warp signature of 10.
Warp signatures reach about one sector in radius per accumulated warp factor. The example signal would reach about 10 sectors. Beyond that it is too weak to be detectable.
The emission of power consumed in solar systems is too revealing, especially for new players. As soon as they start generating power, they can be detected and stomped.
Instead of emitting total power consumed, solar systems now emit a warp signature. The warp signature is a measure of the accumulated warp factors engaged in the system.
Warp signature signals are emitted hourly by solar systems. This is a bit more responsive than the previous energy emissions, which were emitted every six hours.
Airport terminals and base air terminals account for one warp drive engage per hour, at the maximum warp factor available to the empire. Warp technology of an empire is based on the highest patent they know for making a warp drive.
For example, if a ship engages warp at factor 4 and another ship engages warp at factor 2, and the system contains two cities with spaceports owned by empires with warp 2 technology, the solar system will emit an accumulated warp signature of 10.
Warp signatures reach about one sector per accumulated warp factor. The example signal would reach about 10 sectors. Beyond that it is too weak to be detectable.
The signal can be detected by radar of an empire with warp technology and spacecraft with sensors and warp drives. Their warp signature detection range is reported on their analysis report, replacing deep space detection range.
Actual maximum detection range is the lesser of the two values: the range the signal can reach and the detection range of the radar or sensors.
Wording on the star map was updated in appropriate places.
Color and marking of detected systems was changed.
Star map filter settings now includes a check box to turn on/off the warp signature markers on unexplored systems. Previously, the yellow detected markers could not be turned off.
