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. Types of satellite receivers, depending on the model is divided into geodetic type, station type, regular type, hand-held, integrated; according to the application is divided into vehicle-mounted and ship-borne type of airborne, spaceborne, spring-loading. The workshop plans to increase the requirement of manufacturing cell phone blocker.
Proved after 20 years of practice, the GPS system is a high-precision all-weather and global radio navigation, positioning and timing multifunction system. GPS technology has developed into a multi-domain, multi-mode, multi-purpose, multi-model international high-tech industries. 24 GPS satellites in the high altitude of 10 002 to 1000 kilometers above the ground, the 12-hour cycle ring orbiting the earth, so at any time, any point on the ground can be observed simultaneously to more than 4 satellite. Accurate we can see the position of the satellite, the GPS observations, we can get the satellite to receiver distance, the distance formula in three-dimensional coordinates use of the three satellites, can be composed of three equations, solution of the observation position (X , Y, and Z). For the factory gets much more orders of cell phone jammer , the factory needs more workers to accomplish all orders within the specified period.
Taking into account the satellite clock and receiver clock error, in fact, there are four unknowns, the X, Y, and Z-and clock error, and thus need to introduce the four satellites, the formation of four equations to solve, resulting in the observation point latitude, longitude and elevation. In fact, the receiver can often be locked more than 4 satellite, this time, the receiver according to the satellite constellation distribution is divided into several groups, each group of four, and then by the algorithm to pick out a set of minimum error used for positioning, which improve accuracy. As the satellite orbits, satellite clock errors, troposphere, ionosphere on the signal, as well as man-made SA protection policy, making civilian GPS positioning accuracy is only 100 meters. The general manager promises that the bonus will be higher if the worker can complete the tense production task of cell phone jammer .
Commonly used to improve positioning accuracy, differential GPS (DGPS) technology, the establishment of the reference station (differential station) GPS observations, using the known exact coordinates of the base station, were compared with the observed values to arrive at a revised number, and released . The receiver receives the amendment number, with its own observations to eliminate most of the error, get a more accurate location. The experiments show that the use of Differential GPS positioning accuracy can be increased to 5 meters. + H) i _8 e-; Y & _) `0 m, six gyroscopes - K, ^ of 6 g + \ # _2 ^ / K, + u & | * V6 [also known as angular rate sensor, is different from the acceleration meter (the G-sensor) of The measurement of physical quantities is the deflection, the angular velocity when the tilt. The vice manager is showing the technical inspection group around cell phone jammer workshop.
On the phone, only the accelerometer can not measure or reconstruct a complete 3D action undetectable rotating action, the G-sensor can only detect the axial linear motion. Gyroscope to do a good measurement of rotation, the deflection of the action, so that you can accurately analyze the actual action to determine the user. Then according to the action, on the phone to do the appropriate action! ) R3, A, 'i, z; F C-r1} At present, the gyroscope, the most successful application was undoubtedly the somatosensory game in Wii games (Wii Motion Plus) handle on the consumer products, to achieve control of the game . Player holding the Wii Motion Plus handle the video game on the screen can be controlled through their own actions do play table tennis, tennis and other sports games, or turn the handle, you can play a driving video game. The company plans to hold more technical meetings during the production month of cell phone jammer .
