Shenzhen-Electronic Technology Co., Ltd. after the Year of the GPS module Why turn a long time to get positioning data? GPS module cold boot and Hot start two parameters, if the GPS module after initial power circuit board, or move more than 1000 km energized circuit board wiring is good or bad picture can be seen, the module to be re-evaluated once the ephemeris data, the general need 1 to 5 minutes, and then the ephemeris data is stored in the module, save the data by a lithium battery inside the module, called a cold boot, it takes a long time. If the next boot, because the lithium battery has saved valid ephemeris data, we are able to quickly locate, usually within 30 seconds, so called Hot start single-sided circuit board design principle, if the module is off more than 10 hours, lithium battery discharge shine, then re-boot the equivalent of a cold boot. Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, high What quality of Shenzhen circuit board layer board should pay attention to, quality assurance, reasonable prices. As electronic devices become more complex and require more and more natural parts, PCB top of the line and part of more and more intensive. Bare board (top no parts) is also often referred to as 'the printed circuit board Printed Wiring Board (PWB)'. The base board itself is insulated, it is not easy to bend the material made into. Can be seen on the surface of fine copper wiring material, copper foil originally covering the entire board, and in the part of the manufacturing process is etched disposed, he left to become part of the mesh of the fine line . These lines are called conductors or said wiring and circuit components on the PCB to provide a multilayer circuit board connected proofing _ Newell record (certified) _ Hubei board provided by the Department of Shenzhen-Electronic Technology Co., Ltd. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) Guangdong Shenzhen, printed circuit board leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Newell create leadership with the staff warmly welcome all inquiries negotiations to create Newell create a better future.
