Shenzhen Electronic Technology Co., Ltd. Newell how to do cold start if there is a long time can not be positioned? So you need to check whether GPS antenna placement in an open environment, the ability to read GPS data GPS module output? GPS data inside the GSV statements can be observed GPS satellite signal status? From these you can determine what specific issues! Can output per second: $ GPGGA $ GPGSA $ GPGSV $ GPRMC positioning data, we usually use the $ GPRMC streamline data output this information, this information includes the objective of: longitude, latitude, speed (miles / hour) movement direction angle, year, month, hours, minutes, seconds, milliseconds, location data is valid or invalid vital information boards image sample, most chip GPS module or the use of global market share for the first series of SiRFIII Lord, SiRFIII chip 20-channel, real-solving ability. The market is very common part of the module: ring days, Vasco da Gama, Ublox etc. Snyder International Limited Shenzhen Branch Newell Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-pane, double panel, 2 -40 layer multilayer professional supplier, to provide customers with high-precision, high-quality Shenzhen circuit board circuit board, quality assurance, reasonable prices double panel is an extension of single panel, when the single-layer wiring can not meet the needs of electronic products circuit board design features, it is necessary to use a double-sided. Forming a double-sided copper network has had traces and vias can be turned on circuit board between the two layers of gold, so that the desired connection. Multilayer means insulating material having three or more conductive pattern layer therebetween to separated laminated, and during which the conductive pattern of the printed circuit board interconnections required. Multi-layer circuit boards of electronic information technology to high-speed, multi-function, high-capacity, small size, thin, lightweight product development direction. Board by feature points, then into soft board (FPC), hard board (PCB), Rigid-Flex PCB (FPCB).
