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 is powered for the first time, or after power move over 1000 kilometers, the module to be re-evaluated once the ephemeris data, usually takes 1 to 5 minutes, and then the ephemeris data stored in Module internal circuit board solder paint color, by lithium battery to save data 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 boot, if the module is powered down for more than 10 hours, the main function of the board, lithium battery discharge double-sided circuit board copper shine advantage, 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 Shenzhen circuit board quality, quality assurance, reasonable prices. Modern materials are double-sided PCB board CCL, also known as CCL (Copper clad laminate) CCL. CCL is the core of the PCB. CCL depending on the substrate material is divided into three categories, namely, paper board, composite board and three categories of FR-4 circuit board substrate, their characteristics and uses are different, which is the current mainstream FR-4. The computer we use every day all the PCB board, and are based on FR-4 as raw material.
