Shenzhen Electronic Technology Co., Ltd. Newell GPS module has a cold start, warm start and warm start (today's technology has basically the cold start and warm restart mode parameter has done two very close, so warm start on phasing out) three parameters, if the GPS module initial power, or move more than 500 km after power, the module must be recalculated once ephemeris data, GPS module under normal circumstances takes only 30 seconds to the normal position (this is a cold start ) mobile phone circuit board, S-87 has a built-in button batteries, can be inside the module, when the next module can very quickly locate ephemeris data storage, such as S-87 generally requires only 1-3 seconds to achieve a new positioning, and that this positioning is called hot start second order circuit board, if the module is powered down for more than 4 hours, and no real-time RTC internal power supply, then once again the boot is also equivalent to a cold start. Newell hit after Shenzhen Electronic Technology Co., GPS module Why turn a long time to get positioning data? GPS module has a cold boot and warm boot two parameters, if the GPS module initial power Goldfinger board, or move after power over 1000 kilometers, the module to be re-evaluated once the ephemeris data, it normally takes 1-5 minutes, and then the star Calendar data is stored in the module, save the data by internal lithium battery module, called a cold boot, takes a long time. If the next boot, because the lithium battery has saved valid ephemeris data, they are able to quickly locate, generally less than 30 seconds, so I turned on the heat, if the module is powered down for more than 10 hours, the lithium battery discharge shine, then another the equivalent of a cold boot to boot. Second-order circuit board _ Newell hit the board (certified) _ board provided by Shenzhen Electronic Technology Co., Ltd. Newell. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) Guangdong Shenzhen, PCB's leaders over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Newell record in leadership with the staff warmly welcome all inquiries negotiations to create Newell create a better future.
