There is no dispersion whatsoever, after the pulse leaves the GPS day side the cone starts the enlarge to .5 mils depending on the range to the target. In the M1A1SA and the M1A2 SEPV2, the center of the cone is the center dot of the reticle. There is no offset. Optical requirements of the fire control system are minimized by integrating the laser into the gunner's primary sight. The primary aiming reticle and laser beam are combined in the laser transceiver to ensure accurate alignment. The gunner's primary sight optical relay to the commander's station provides full day and night vision fire control capability for the commander. A backup main gun aiming capability is provided by the Gunner's Auxiliary Sight. The LRF is mounted on the GPS Body. When the gunner (or commander) pushes the RANGE thumb button on the control handle, the laser fires pulses along the LOS. The reflected laser pluses return along the same LOS back to the LRF, which calculates range to target.
