The Kerrison Predictor was one of the first fully automated anti-aircraft fire-control systems. It was used to automate the aiming of the British Army's Bofors 40 mm guns and provide accurate lead calculations through simple inputs on three main handwheels.
The Aviation Section, Signal Corps, was the aerial warfare service of the United States from 1914 to 1918, and a direct statutory ancestor of the United States Air Force.
Linear prediction is a mathematical operation where future values of a discrete-time signal are estimated as a linear function of previous samples. In digital signal processing, linear prediction is often called linear predictive coding (LPC) and can thus be viewed as a subset of filter theory.
The Aeronautical Division, Signal Corps (1907–1914) was the first heavier-than-air military aviation organization in history and the progenitor of the United States Air Force. A component of the U.S. Army Signal Corps , the Aeronautical Division procured the first powered military aircraft in 1909, created schools to train its aviators, and ...
Air traffic control signal light guns are typically specified with a (white) center beam brightness of > 180,000 - 200,000 candela, and are visible for roughly 4 miles in clear daylight conditions. The table below describes the meaning of the signals.
The Longley–Rice model (LR) is a radio propagation model: a method for predicting the attenuation of radio signals for a telecommunication link in the frequency range of 40 MHz to 100 GHz. [1] Longley-Rice is also known as the irregular terrain model (ITM).
An aviator call sign or aviator callsign is a call sign given to a military pilot, flight officer, and even some enlisted aviators. The call sign is a specialized form of nickname that is used as a substitute for the aviator's given name.
Linear prediction (signal estimation) goes back to at least the 1940s when Norbert Wiener developed a mathematical theory for calculating the best filters and predictors for detecting signals hidden in noise.
The industry grew rapidly and ground crews initially relied on coloured paddles, signal flares, hand signs, and other visual aids to communicate with incoming and outgoing aircraft. Although these methods were effective for ground crews, they offered no way for pilots to communicate back.
Correction is made until the vertical needle centres, meaning the aircraft has intercepted the given course line. The pilot then steers to stay on that line. Only the receiver's current position determines the reading: the aircraft's heading, orientation, and track are not indicated.
