Modifiers for Electronics (sensors) checks

[lord_bosco]

Seems like this should be in the referee's screen:

Sensors:
To detect a target with the sensors of vehicle or spaceship roll an Average (8+) Electronics (sensors) check (1D seconds, INT).

Spaceship sensors:
Using basic spaceship sensors: -4
Civilian spaceship sensors: -2
Military spaceship sensors: 0
Improved sensors: +1
Advanced sensors: +2
Using Expert software: +1 if you already have Electronics (Sensors) skill
Using Improved Signal Processing: +2 (High Guard 42)
Using Enhanced Signal Processing: +4 (HG 31)
Target vehicle or spaceship has transponder turned on: +4 (Core RuleBook 146)
Target is using active radar or lidar: +2 (CRB 151)
Target has Energy Absorption Grid: -2 (HG 12)
Target has stealth tech: -4 and -1 per TL better then sensor system (HG 13)
Target has superior stealth: -6 and -1 per TL better (HG 13)
Target ship 100,000 tons or greater: +2 (HG 24)
Target ship 500,000 tons or greater: +4 (HG 24)
Target has Extended Arrays open: +2 (HG 31)
Target is TL10 assault capsule: -2 (HG 46)
Target is TL14 assault capsule: -4 (HG 46)
Target living creature is attempting to hide: opposed by target's Stealth check (CRB 79)
Target wearing armor with Chameleon, IR option: -4 to IR sensors (CRB 96)
Chaff cloud blocking line of sight: -1 (HG 31)
Damaged sensors spacecraft quirk: -1 (CRB 64)
Severity 1 critical hit to sensor systems: -2 (CRB 159)
Electronic Warfare using a Countermeasures Suite: +4 (HG 41)
Electronic Warfare using a Military Countermeasures Suite: +6 (HG 42)
Electronic Warfare against target with Improved Signal Processing: double positive DMs (HG 42)
Electronic Warfare software: +1 per software level to Electronic Warfare checks (HG 64)

Vehicle sensors:
Basic vehicle sensors: +0
Improved vehicle sensors: +1
Advanced vehicle sensors: +2
Hardened: ignore -1 of Electronic Warfare penalty
Increased fidelity: +1 per level
Using Expert software: +1 if you already have Electronics (Sensors) skill
Using bio-tech underwater sensors: +2 (Vehicle Handbook 62)
Target vehicle or spaceship has transponder turned on: +4 (CRB 146)
Target is using active radar or lidar: +2 (CRB 151)
Target within one-half the vehicle sensor's maximum range: +2 (VH page 3)
Target within one-quarter maximum sensor range: +4 (VH 3)
For every 25 spaces target vehicle has: +1 (VH 3)
Target hiding in cover: -2 (VH 3)
No line of sight: TL11 or better sensors required to detect. (VH 3)
Target is bio-tech: -1 to radar/lidar, +1 to IR/thermal (VH 62)
Target has basic stealth technology: -1 and -1 per TL better (VH 55)
Improved stealth: -2 and -1 per TL better (VH 55)
Advanced stealth: -4 and -1 per TL better (VH 55)
Stealth does not work against sensor/comm systems of superior TL
Target living creature is attempting to hide: opposed by target's Stealth check (CRB 79)
Target wearing armor with Chameleon, IR option: -4 to IR sensors (CRB 96)
Faulty sensors vehicle quirk: -4 (VH 4)
Severity 1 critical hit to electronic systems: -2 (CRB 135)
Within range of enemy ECM system: -1 per TL better then sensor/comm system (VH 52)
Improved ECM: -1 and -1 per TL better (VH 52)
Advanced ECM: -2 and -1 per TL better (VH 52)
ECM does not work against sensor/comm systems of superior TL

That’s a good list, thanks!

 

[Annatar Giftbringer]

Great work, thanks for sharing!

 

[AnotherDilbert]

Great collection!

Don't forget Range: At Very Distant range the sensor task becomes Formidable, almost the same as DM -6 (HG p24).

A Sub-Command Centre can give an additional +1 DM (Element Class Cruiser).

A Sensor Lock gives a Boon on the sensor task (Core p161).

Nice list!

Most of us already know this, but not all sensor checks are for detection, thus some equipment might help only detection or electronic warfare (countermeasure suit) or does not stack with other modifiers (countermeasure suit).
