Russian ballistic missile ring laser gyroscopes for missile guidance!


Russian ballistic missile ring laser gyroscopes for missile guidance! Two laser beams are generated & travel in opposite directions within a ring-shaped cavity. When the gyro rotates, the effective path length for each beam changes slightly due to the Sagnac effect. 1/5

Considering that each group of RVs takes about 0.5s to reach the ground from the cloud, which is about 2 km from the earth's surface, the RVs reach the ground at a speed of about 4 km/s or almost Mach 12. This is breathtaking & staggering! There is no defense against it! 1/4

Drift rate is typically 0.001 to 0.01 degrees per hour for high-end systems. High-grade RLGs used in intercontinental ballistic missiles or submarine-launched ballistic missiles provide a circular error probable (CEP) of 200-500 meters or better over intercontinental ranges (10000 km+). The U.S. Minuteman III or the Russian RS-24 Yars, the gyros contribute to a CEP of 90-200 meters when paired with other guidance aids like star trackers or GPS. So the Russian medium-range ballistic missile Oreshnik will probably have a CEP of around 40-90 meters at a distance of 3000 km! 5/5
