Zhengzhou wireless GPS positioning system, GPS positioning long standby Zhengzhou, Zhengzhou wireless GPS manufacturers, wireless gps positioning wholesale Zhengzhou, Zhengzhou wireless GPS positioning GPS wiring free agent where to sell, Zhengzhou VPS factory outlets, Zhengzhou car positioning system. Miniature wireless GPS vehicle positioning terminal is based on a volume Depot Company users need to develop compact, easy to install, self-powered terminal device tracking location, low power consumption, long working hours, and widely used, car installments , auto loans, construction machinery, mobile asset management, which is characterized as follows: 1: beautiful and compact design, the device without external wiring, no external antenna lead, easy to install and easy to conceal. 2: anti-scan products, shell fire-retardant material, waterproof rating to IP65. 3: Long life design, relying on the built-in battery and energy management strategy can work for three years (depending on the work environment are different). 4: Using GPS, LBS double positioning, positioning is more reliable. The default network platform to report once a day to locate information. 5: In the case of frequent track vehicles can be temporarily set to emergency mode, that is, within a predetermined period to a shorter period reported location information. 6. There is too easy to add wired gps, is to find the car artifact wind control of the vehicle. Customers often ask, your home car GPS positioning accuracy how much? Actual said GPS satellite positioning system in the United States. Positioning accuracy for civilian and military two points, affected by the US Open civilian accuracy within 5-100 meters. While the impact of gps positioning accuracy there are many factors, but open precision other people can not be changed. Is the biggest determinant of positioning accuracy. Whose are the same. GPS products sold on the market, said his position as the accuracy of 3-5 meters are deceptive, please do not be fooled through China differential GPS positioning technology after the United States have at least 10 meters away from the error, so it is within 15 meters is the exact value of the GPS positioning. This is only theoretical positioning accuracy. The same theory as car fuel consumption is a theoretical ideal. Also gps positioning accuracy in the use of which is a coordinate point on the map to locate the coordinates of another point. Coordinate reference point may be a gas station GPS-free wiring much money, it could be a plot, different frame of reference, giving the feeling of different errors. Factors Affecting gps positioning accuracy are: 1, the atmosphere (ionosphere and troposphere delay of GPS signals) 2, multipath (reflected to the receiver through the other surface of the antenna in the GPS signal) 3, the number of GPS satellites currently visible 4 , the currently visible GPS satellites geometric distribution 5, GPS satellite clock error 6, GPS satellites orbit differential, disturbance-free wiring GPS locator, such as SA policy, microwave transmitting devices, 8, GPS positioning mold section 9, + gps positioning and not at any time, any place can locate the GPS search star on many factors, based on the principle of the GPS system, GPS receiver Star Search is strongly dependent on the ability of the satellite signal in the sky, simple language that relies heavily on open sky environment, GPS can be directly exposed to the greater range of high-altitude environment, the satellite signal receiver to search the more stable, more accurate positioning can avoid wiring GPS positioning | Jiaozuo free wired GPS | GPS price from Zhengzhou free wiring Double Electronic Technology Limited.
