G - 003 Tri - Tracker The G - 003 Tri - Tracker was built by CoMar Combat Systems . Description . Built by CoMar Combat Systems , the G - 003 Tri - Tracker utilized a triple - array sensor and computing package known as the Target Acquisition and Tracking ( TAT ) to accomplish three tasks . The first task was to establish a signature lock on all targets of interest in the weapon ' s vector of interest as designated by the operator . The operator or the onboard computer would then select a primary target , while the computer continued to update the list of alternate targets . The second task was to record and track the target ' s position relative to the weapon as well as its evasive maneuvers . This data was transmitted to the Countermeasures Compensation Computer ( C3 ) — a unique sensor and brain combination — which analyzed and tracked the target ' s countermeasures , such as sensor jamming , chaff , or drone s . It then extrapolated and predicted the target ' s flight path , compensating for these variables when the weapon was fired . As the C3 unit continued to track even receding targets , the operator was able to shoot at them with extreme accuracy . Many pilots found themselves victims to a long - distance " parting shot " while believing themselves to be out of range of the Tri - Tracker . The G - 003 had a minimum range of twenty Imperial standard meter s , and a maximum range of sixteen thousand meters . Each shot had a ten meter blast radius , and the power output of the Tri - Tracker ' s weapon blast was comparable to the output of a Star Destroyer ' s turbolaser hardpoint . The accuracy of the G - 003 Tri - Tracker was improved through the application of a tri - beam burst that bracketed the designated target ' s predicted location . The C3 unit made minor adjustments right up to the point the weapon fired . G - 003 Tri - Trackers had a slow rate of fire due to the complexity of the weapon ' s targeting and firing system , and it required three times longer to reset than it did to fire . The sensor system of the Tri - Tracker had a short range , falling far short of the effective firing range of the weapon . This deficiency was compensated for by the TAT ' s ability to extrapolate and predict a flight path for the target craft even beyond the weapon ' s sensor limits . G - 003 Tri - Trackers drew power by either been connected to a mains land - line , a power generator , or from a reserve battery . Although the battery option appealed due to the options for portability for the weapon , it was seldom employed due the power - hungry nature of the weapon , and the battery only gave the weapon forty shots . Connection to land - based power lines and generators was the preferred option . A two man - crew was required to operate the G - 003 Tri - Tracker . One fired the weapon while the second selected and prioritized targets in the TAT . The Tri - Tracker could be operated by a single crewmember , but the weapon lost forty percent of its accuracy during the target acquisition process . Droids , specifically programmed to operate the Tri - Tracker , could man the weapon in place of qualified organic operators . The G - 003 was designed for use in a permanent emplacement , or as part of a mobile defense with the use of a heavy - duty repulsor sled . However , the G - 003 required a long time for set - up and calibration when installed , meaning it was not popular for use as a mobile emplacement . It was generally used in its mobile form only when employed as part of a long - term defensive position . G - 003s cost 50 , 000 credits to purchase new , and 25 , 000 used . History . The G - 003 Tri - Tracker was designed for the Imperial Military to combat enemy atmospheric threats . Using proven technology from the " Imperial " - class Star Destroyer weapons technology , CoMar developed the most accurate surface - to - air defense system for the Galactic Empire . Due to the Tri - Tracker ' s slow rate of fire , a concentrated air attack against the emplacements was capable of overwhelming them . With this mind , Tri - Trackers were commonly employed as a part of a larger , interlinked network of air defense emplacements . When employed in this fashion , a network fire control system was used to coordinate the TAT for maximum target coverage .
