Connectors For Car Audio
Several types of connectors for car audio systems are used. Splicing wires Splicing wires used in car audio are mainly for power, ground, amplifier and antenna, speakers, phone and others. Power and ground * ACC (red), supplies +12V power to car audio and other accessories, only when the car's ignition is switched on. * Constant (yellow), also called BAT or Battery, provides permanent +12V power from battery. This allows the radio to retain settings (for example, stored radio stations) when the ignition is switched off. * Illumination (orange with white stripe) or dimmer, when it is night and cars lights are turned on, head unit screen illumination is dimmed. * Ground, abbrev. as GND (black), 0V, usually connected to the vehicle's metal chassis and body. Speakers Wires with black stripes are for negative power: * Right front speaker: gray. * Left front speaker: white. * Right rear: purple. * Left rear: green. Amplifier and Antenna They have low electric current, which is acti ...

Electrical Splice
In telecommunications, a line splice is a method of connecting electrical cables (electrical splice) or optical fibers (optical splice). Splices are often housed in sleeves to protect against external influences. Splicing of copper wires The splicing of copper wires happens in the following steps: * The cores are laid one above the other at the junction. * The wires are wrapped two to three times around each other ( twisting). * The core insulation is removed. * The bare veins on a length of about 3 cm "strangle" or "twist". In some cases, the strangulation is soldered. * To isolate the splice, an insulating sleeve made of paper or plastic is pushed over it. The splicing of copper wires is mainly used on paper insulated wires. LSA techniques (LSA: soldering, screwing and stripping free) are used to connect copper wires, making the copper wires faster and easier to connect. LSA techniques include: * Wire connection sleeves (AVH = Adernverbindungshülsen) and other cr ...

Vauxhall Astra
The Vauxhall Astra is a compact car/small family car (C-segment) that has been sold by Vauxhall since 1980. It is currently produced at Ellesmere Port, Cheshire, England. For its first two generations, the nameplate was applied to right-hand drive versions of the Opel Kadett for use in the UK. Since 1991, Opel has used the Astra nameplate on its B/C-platform. General Motors' Saturn division in the United States also offered a Belgian-built version of the Astra as a captive import from late 2007 until Saturn was discontinued following GM's 2010 bankruptcy. First generation (1980–1984) The Astra name originated with the Vauxhall-badged version of the first front-wheel drive Opel Kadett, which had been launched in 1979 as the Opel Kadett D. This model, which went on sale in March 1980, replaced the Vauxhall Viva in the UK. The last rear-wheel drive Kadett had also formed the basis of the Vauxhall Chevette, which remained in production until 1984. The Astra was Va ...

Satellite Navigation System
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...
