7.62mm高精度狙击步枪系统中的GS/OB1型手持激光测距仪/弹道解算计算机从2009年2月开始研制,同年12月研制成功。该设备是一种具有弹道解算功能的激光测距仪,主要用于协助狙击手对目标进行侦察,并通过弹种选择,以及对目标距离、角度、环境温度、湿度、气压等参数进行测量,再根据手工输入的风力、风向参数,自动进行外弹道修正参数的解算,为狙击手修正射击瞄准点,完成精确打击提供信息参考—— The GS / OB1 handheld laser range finder / ballistic solution computer in the 7.62mm high precision sniper rifle system was developed from February 2009 and was successfully developed in December of the same year. The device is a laser range finder with ballistic solver, which is mainly used to assist the sniper to detect the target and measure the target distance, angle, ambient temperature, humidity, air pressure and other parameters , And then manually input the wind and wind parameters automatically solve the ballistic correction parameters for the sniper to modify the shooting aiming point to provide accurate information to provide accurate reference -
