This system has the capability to identify the type, and sometimes even class, of a vessel while ins pace. The SIID system is rather ineffective when trying to identify vessels at a long range or when the target vessel is in motion. The system itself is rather small and merely coordinates and translates information transmitted by the ship's computer to the ship sensors and visa versa. The SIID system marks the exact moment a radar transmission is sent from the ship's sensors to the exact moment the transmission returns. From this measurement, the computer can figure not only the exact distance of the vessel being scanned, but can also create a visual representation of the "target" vessel. This picture is then compared to the starship catalog computer program aboard and attempt to identify the target ship's type. If the SIID system identifies the target, and even if it does not, it will notify the appropriate person on the bridge. This person is often the weapons control officer on larger ships. The system can differentiate between asteroids, debris and other space junk, but it may not be able to see starships hidden inside of an asteroid belt or a planetoid monitor. The SIID is subject to many forms of jamming.

SHORT RANGE: Target stationary: 3+ to identify; Target moving: 4+ to identify (Short range DM: +1 per 1,000 tons of the target vessel; -5 if acceleration is 4G or higher).

LONG RANGE: Stationary target: 10+; Moving target: 11+ (DM: +1 per 5,000 tons of target vessel; -2 if target moving at 2G acceleration or higher).

Cost: Cr24,000 (for system and installation; base price is Cr20,000). Starship catalog computer program: Cr1,500 (required for operation of SIID; contains statistics and also external views of all known fleet and merchant vessels; no floor plans.) TL10. Weight: 100kg.

Basically an attachment to the SIID system which is the result of a higher technological level. SIIDX is almost guaranteed to identify a vessel at a short range and has improved chances of identifying moving vessels at a long range. SIIDX is subject to jamming. SIID system required for SIIDX to operate, but only the SIID computer software is necessary.

SHORT RANGE: Stationary: Auto; Moving: 3+ (DM: +1 per 1,000 tons of the target; -1 per 1G acceleration of the target).

LONG RANGE: Stationary: 8+; Moving: 9+ (DM: +1 per 5,000 tons of the target; -2 per 1G acceleration of the target).

Cost: Cr15,000 (for system and installation, base price Cr13,000). TL11. Weight: 25kg.

Also called PSES, this system is no more than a high tech sonar device that can measure the distance between the host vessel and any given point on a planetary surface. PSES is not effective when trying to measure the depths of a body of water. PSES can be used with a ship's standard sensors, but it would not allow the vessel to navigate safely or detect other objects. For this very reason, PSES is now only produced as a single system with its own sensors and computer software. Most forms of static and interference are filtered out by the PSES system. Areas covered by any form of severe weather generally can't be plotted by PSES. PSES is subject to jamming and is connected to the ship's computer.

Cost: Cr35,000 (system and installation; base price: Cr32,000); TL8. Weight: 115kg.

An extremely complex system which is connected to every functional device on a starship, mechanical and electrical. This system can locate any malfunctions in a matter of seconds after they occur. (This is only possible when the DR is running; it is advised to keep DR in operation at all times if possible). A computer program is required. Cannot be jammed.

Cost: Cr100,000 plus Cr40,000 per additional 1,000 tons (Installation included); TL9 (higher TL versions are available); Computer program: Cr9,500. Weight: 100kg per 1,000 tons of vessel tonnage.
