Terminology:Sensors

Terminology

---

Sensors is the general term for systems allowing a vessel to detect other objects in space.

Usage in Vegastrike

What does it do

Sensors detect and recognize other objects as well as provide missile targetting. Military sensors also may have Terminology:ITTS capability, in which case they only provide targetting data - to actually aim a weapon automatically, its hardpoint must have autotracking system installed.

Tracks of the objects harder to pinpoint than usual - such as ships with active ECM systems and nebulae - has noticeable jitter.

Available Sensor Types

Currently, supported possible types of sensor functionality (recognized for units and upgrades in unit.csv) are:

Type	Projection	Friend-or-Foe	Object Recognition	Threat Assessment	comment
0 (FALSE)	Spherical	no	no	no	all tracks look the same way
1 (TRUE)	Spherical	yes	no	no
THREAT	Spherical	yes	no	yes
BUBBLE_THREAT	Bubble	yes	yes	yes	Rlaan sensors are designed like that
PLANE	Plane	yes	no	no
PLANE_THREAT	Plane	yes	yes	yes	good for short-range fighting

Displayed Projections

There are several different display modes, currently fixed for given sensor hardware:

• Spherical (Wing Commander style) - two circles, for fore and aft hemispheres. Allows easy orientation on a chosen track, but doesn't show distance at all.
• Bubble - the same, but tracks are displayed as circles, blown more or less to represent objects' velocity. Terminology:Rlaan sensors are designed like this.
• Plane (Elite style) - cylindrical projection, showing the place of a track in the unit's "horizontal" plane (thus making ranges obvious) and "height" from it.

Advanced functions

Track color-coding by Threat Assessment has priority over Object Recognition, and that over Friend-or-Foe. I.e. if all 3 are present, all missiles are colored the same way, and all planets are colored the same way, no matter to whom they belong.

Friend-or-Foe

Friend-or-Foe is a basic target assessment capability which discerns (and color-codes):

Capital Ship Ship	friend	enemy	neutral
		or has lock	this includes unarmed enemies if Threat Assessment is present
Cargo Container	Cargo
anything else	normal

Object Recognition

Object Recognition shows tracks color-coded by object type:

Star Nebula	star
Planet Dead Planet	planet
Base	base	enemy
		if it has lock
Jump Point	jump
anything else	normal

Threat Assessment

Threat Assessment shows tracks color-coded for missiles and blinking for objects that has lock on the player's ship - the greater its perceived threat, the faster is blinking:

Missile

missile

Threat level:

Missile	High
Capital Ship		Medium if hostile	Low otherwise
Ship		Medium if has turrets	Low otherwise	None if unarmed
