A gyro gunsight (G.G.S.) is a modification of the non-magnifying reflector sight in which target lead (the amount of aim-off in front of a moving target) and bullet drop are calculated automatically. The first examples were developed in Britain just before the Second World War for use during aerial combat , and more advanced models were common ...
The kit allows US Special Operations Forces (US SOF) personnel to configure their weapons to individual preferences and customize for different mission requirements. The program dates back to September 1989, when the Special Operations Special Technology (SOST) Modular Close Combat Carbine Project was founded. This was the first program to ...
Open sights (also known as "mini reflex sights" and "mini red dots") take advantage of the fact that the reflector sight's only optical element, the optical window, does not need any housing at all. This configuration consists of a base with just the necessary reflective surface for collimating the reticle mounted on it.
The Sperry Horizon, Sperry Gyroscope Co. Brooklyn N.Y.. The company was incorporated on April 14 1910 [2] by Elmer Ambrose Sperry as the Sperry Gyroscope Company, to manufacture navigation equipment—chiefly his own inventions: the marine gyrostabilizer and the gyrocompass—at 40 Flatbush Avenue Extension in Downtown Brooklyn.

The lower gyro has its spin axis oriented along the east–west grid axis and is sensitive to torques about the north–south and vertical axes. Therefore, the two gyros control all three axes. Platform gimbals are the assemblies which actually keep the platform accelerometers stable and enable the airplane to maneuver about the gyro-stabilized ...
The problem of computing the gyro angle setting is a trigonometry problem that is simplified by first considering the calculation of the deflection angle, which ignores torpedo ballistics and parallax. [44] For small gyro angles, θ Gyro ≈ θ Bearing − θ Deflection. A direct application of the law of sines to Figure 3 produces Equation 1.
According to the Sagnac effect, rotation induces a small difference between the time it takes light to traverse the ring in the two directions.This introduces a tiny separation between the frequencies of the counter-propagating beams, a motion of the standing wave pattern within the ring, and thus a beat pattern when those two beams interfere outside the ring.
A HRG gyrocompass is a compass and instrument of navigation.It is the latest [when?] generation of maintenance-free instruments.. It uses a hemispherical resonant gyroscope, accelerometers and computers to compute true north.
