Ship Sensor Suite

A Ship Sensor Suite is the detection package equipped in most, but not all ships.

• It is comprised of a number of different sensors including Densitometers, RADAR, LIDAR, and more.
• It is an item of Ship Equipment.
• Please also see AAB article: Sensor.

Description (Specifications)

Ship sensor suites are available in three different qualities:

1. Civilian Quality Sensor Suite: sometimes referred to as a "basic sensor array".
2. Paramilitary Quality Sensor Suite: sometimes referred to as a "standard sensor array".
3. Military Quality Sensor Suite: sometimes referred to as an "advanced sensor array".

Notes: The actual quantity and quality of sensors within the suite may vary from model to model, and between ship class, manufacturer's lot, or block. There may be other subtle distinguishments such as characteristic faults or "blind spots" in coverage.

Sensor Types

Ancillary Equipment

• Antenna, dishes and aerials (transmitters and receivers). A concentration of such equipment may be referred to as an "antenna farm".

Acoustic Equipment

• Audio Pinger (does not function in a vacuum: it relies on a gas, a fluid or a solid to carry sound) (Active Sensor)
• Audio Sensor (microphone, listening device) (does not function in a vacuum: it relies on a gas, a fluid or a solid to carry sound) (Passive Sensor)

Electromagnetic Spectrum Sensors

• Active IR (infrared radiation, thermal imaging) (Active Sensor)
• Laser / Light Sensors (Passive Sensor)
• LIDAR (Light Detection and Ranging) – also called LADAR (Laser Detection and Ranging) (Active Sensor)
  • Prismatic (anti-laser) aerosol (countermeasure)
• Magnetic Sensor (Passive Sensor)
• Neutrino Sensor (Passive Sensor)
• Passive IR (infrared radiation, thermal imaging) (Passive Sensor)
• RADAR (Radio Detection and Ranging) (Active Sensor)
  • All-weather RADAR (improved function in a variety of environmental conditions) (Active Sensor)
  • RADAR Direction Finder (Passive Sensor)
  • RADAR Jammer (Active ECM)
• Radiation Sensor (Passive Sensor)
• Radio Detector (Communications Equipment) (Passive Sensor)
  • Radio Direction Finder (Passive Sensor)
  • Radio Jammer (Active ECM)
• UV Detector (ultraviolet radiation) (Passive Sensor)

Gravitic Equipment

• Densitometer (gravitic sensor) (Passive Sensor)

Navigational Aids

• Inertial Locator (navigational aid, data improvement)

Optical Instruments

• Cameras, devices and telescopes sensitive to energy across the visible spectrum (Passive Sensors)
• Image enhancement (data improvement)
• Light amplification (data improvement)
• Lights (visible wavelengths of light: a torch or a spotlight) (Active Sensor, data improvement)
• SIID (Starship Image Identification) (may also be referred to as SOIID – Space Object Image Identification) (Passive Sensor)
  • SIID Enhancer (SIIDX) (data improvement)

Survey Equipment

• Planetary Surface Elevation Scanner (surveying equipment) (Active Sensor)

Volatiles Testers / Biosensors

• Atmosphere Tester (sample analysis) (Passive Sensor)
• Bioscanner (sample analysis) (Passive Sensor)
• Neural Activity Sensor (passive Sensor)

Vessels may mount other small, specialized sensors such as anemometers, seismometers, motion detectors or pressure sensors.

• Onboard and internal sensor devices may be tied in to the ship's Anti-hijack Program.

Sensor Packages

A comprehensive and optimized collection of sensors and electronic systems assembled as a single compact unit.

• Sensor Packages are available in "basic", "standard" and "advanced" types.

Package Types

• EMS Active Array (Broad Electromagnetic Spectrum) (Active Sensors)
  • Includes RADAR, all-weather RADAR, LADAR, RADAR jammer, radio jammer, active IR imaging, and image enhancement.
• EMS Passive Array (Broad Electromagnetic Spectrum) (Passive Sensors)
  • Includes laser sensor, RADAR direction finder, radio direction finder, Radiation Sensor, passive IR, optical instruments and cameras, light amplification, and image enhancement.
• EMS Jammer (Broad Electromagnetic Spectrum) (Active ECM)

Accessories

• Avionics
• Self-Diagnostic Trouble Shooter

History & Background (Dossier)

Sensor Detection:

• Ordinary or commercial starships (typically equipped with "basic" grade sensors) can detect other ships out to a range of about one-half light-second; about 150,000 kilometers.
• Scout or mercenary starships (utilizing "standard" grade sensors) and Military vessels (mounting "advanced" grade sensors) have detection ranges out to two light-seconds; 600,000 kilometers.

Active Sensors

• Ships using active sensors or broadcasting using Communications Equipment are significantly more easy to detect: they are advertising their presence.

Silent Running:

• Ships which are maintaining complete silence (relying on passive sensor systems) cannot be detected at distances of greater than half detection range; ships in orbit around a world and also maintaining complete silence cannot be detected at distances greater than one-eighth detection range.
• Ships may power down onboard systems, such as the power plant, to reduce their emitted signature.
• Ships may attempt to use planetary masses and stars for concealment. A ship hidden "behind" such an object will almost always be completely concealed from detection.

Vessel Tracking:

• Once a vessel has been detected, it can be tracked by anyone up to three light-seconds (about 900,000 kilometers).
