cell phone jammer makes use of mini-power interference technology

 cell phone jammer makes use of mini-power interference technology.
The light sensor is located before the camera next to a small point, lit (outdoor lighting adequate indoor), keyboard light will automatically switch off after about 2-3 seconds, even if you operate the machine, the keyboard lights will not light unless the low light, a keypad light will automatically light up; lit, you try to hand on the cover the light sensor, after 2-3 seconds, the keyboard The light will automatically light up, this is the role of the light sensor is to play a power-saving features, after all, this machine is a lot of power. How to detect light sensor problem. Quality Assurance Department plans to hold a meeting to discuss the quality feedback of cell phone jammer from the customer.
In standby mode, the phone vice the left side of the camera's light sensor with your fingers to cover the "hang up" key, the phone's keypad lights should turn on, the LCD backlight should be darker. If your keyboard light does not like the above changes, but in any case are lit, then your machine is a problem with the. It is from the circular orbit in a satellite positioning system, accurate positioning and high-precision time base for most of the Earth's surface region. The system is completed by the 24 GPS satellites in space. Requires a minimum of 3 satellite, you can quickly determine your location on Earth. Can the number of satellites received more decoding the location is more accurate. The working instruction of cell phone jammer can guide the operation of cell phone jammer .
Global Positioning System consists of three parts: (1) ground control segment, by the Master Control Station (responsible for the management, coordination of the work of the entire ground control systems), ground antenna (under the control of the master station to the satellite into the searching message), Stations (automatic data collection center) and communication aids (data transmission); (2) of the space segment, composed by 24 satellites, distributed in the plane of the six channel; (3) part of the user device, the GPS receiver and satellite dishes. The main purpose of the Global Positioning System: (1) land application, including vehicle navigation, emergency response, the observation of Atmospheric Physics, Geophysics, resource exploration, engineering surveying and deformation monitoring crustal movement monitoring, municipal planning and control. Different customers have different requirements about cell phone jammer .The appearance of sparking might happen when turning on or off cell phone jammer
Marine applications, including ocean-going vessels the best flight route determination, real-time scheduling and navigation of vessels, marine rescue, marine treasure hunters, hydro-geological survey, and the positioning of offshore platforms, eustatic sea level monitoring; (3) aerospace applications, including aircraft navigation airborne remote sensing attitude control, orbit determination of LEO satellite, missile guidance, air rescue and manned spacecraft protection probe.
