system offers wide and narrow FOVs, correspondingly: 10.7° × 8° and 3.3° × 2.5°. The thermal imaging system utilizes a French sensor coupled with Polish hardware. It can be readied for operation in less than 6 minutes, with the temperature of the environment at the level of 20 degrees Celsius. It works within the range of 8 – 12 µm, NETD up to < 30 mK. Resolution is 640 x 512 px. The laser range finder is safe to the human eye. It can be used at distances between 100 meters and 10 kilometers. The minimum distance between the targets is 10 meters. The instrument offers a 5-meter accuracy level. The sensor on the top of the turret features an armored housing, with a protection level equivalent to the protection levels offered by the turret. Interestingly, the cover may move (partially) independently from the sensor. The optics are not protected with the use of an armored shutter (similar to solutions employed in the case of some MBTs). It is enough to turn the sensor (along with its armored housing) 180 degrees back. This takes 3-4 seconds, and this time is equivalent to the time needed to open the shutter on an MBT. Rearwards left of the panoramic commander's sight, one can find a sprinkler/drying system, making it possible to clean the optics in combat. The sensor, without its armor housing, weighs 40 kilograms. It uses up to 250 W of power. GOC-1 Nike is the primary targeting system. Development of this system took place at PCO, with contributions made by the engineering teams from WB Electronics. Despite the different appearance, its performance and sensors are almost identical to GOD-1. However, its thermal imager works in the 3-5 μm range, while the elevation movement range is smaller (-10° ÷ +60°). The sight in question features a washer/sprayer assembly, a drying system, and an armored shutter of its own. Both targeting systems have been designed with the use of a video tracker in mind. The designers also took great care about the stabilizer systems of high quality. Target detection ranges are an obvious question here. Here one should be aware that this matter is fluid, and depends on numerous factors. We differentiate target detection, recognition, and ID ranges. The whole system is standardized, in line with the STANAG 4347 norm for a 2.3x2.3 meter target, with an assumption that background temperature is at the level of 14.85 degrees Celsius, with the target area being 2 degrees warmer, or colder, in relation to the background. One shall remember that narrow and wide fields of view are available in the case of optics. The GOD-1's thermal imager has detection/recognition/ ID ranges of 4,950/1,600/800 meters. For the narrow FOV, these values are, correspondingly, as follows: 11,000/4,800/2,400 m. The daytime camera of this sight offers performance figures as follows: 5,500/1,800/900 meters for wide FOV and 12,500/4,800/2,500 meters for narrow FOV. Meanwhile, the GOC-1 sight offers slightly worse parameters for the wide FOV, but its performance is far better in the narrow FOV when it comes to target identification (2,500 meters). The daytime camera's performance is inferior - for wide FOV it's 4,000/2,000/800 meters, and for narrow: 7,500/4,000/1,800 meters. So, how do the above STANAG values work in real life? First, in Poland, the typical direct observation distance ranges from 800 to 1,500 meters. And here, GOC-1 and GOD- 1 systems are sufficient. One should ANALYSIS
