Multifunctional Information Distribution System (MIDS) is the NATO name for the communication component of Link-16 developed by Xetron. [1]MIDS is an advanced command, control, communications, computing and intelligence system incorporating high-capacity, jam-resistant, digital communication links for exchange of near real-time tactical information, including both data and voice, among air ...
Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...
A trunked radio system is a two-way radio system that uses a control channel to automatically assign frequency channels to groups of user radios. In a traditional half-duplex land mobile radio system a group of users (a talkgroup ) with mobile and portable two-way radios communicate over a single shared radio channel, with one user at a time ...
The AN/VRC-12 is the lowest-numbered element of a family of vehicular VHF-FM synthesized vehicular radio communications systems developed by Avco Corporation [1] and introduced around 1963 and used extensively by the U.S. military during the Vietnam War and for many years after.
The servo is controlled by three wires: ground, power, and control. The servo will move based on the pulses sent over the control wire, which set the angle of the actuator arm. The servo expects a pulse every 20 ms in order to gain correct information about the angle. The width of the servo pulse dictates the range of the servo's angular motion.
The Wikipedia will use its language if the SVG file supports that language. For example, the German Wikipedia will use German if the SVG file has German. To embed this file in a particular language use the lang parameter with the appropriate language code, e.g. [[File:Radio Transmission Diagram en.svg|lang=en]] for the English
Other examples are fly-by-wire systems in aircraft which use servos to actuate the aircraft's control surfaces, and radio-controlled models which use RC servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the lens. A hard disk drive has a magnetic servo system with sub-micrometer positioning accuracy ...
The ARC-231 Skyfire is a software-definable radio for military aircraft that provides two-way, multi-mode voice and data communications over a 30 to 512 MHz frequency range. It covers both line-of-sight Ultra High Frequency (UHF) and Very High Frequency (VHF) bands with AM , FM and SATCOM capabilities, [ 1 ] including Integrated Waveform (IW).
