Shenzhen Electronic Technology Co., Ltd. Newell GPS module has a number of channels of parameters, such as channel 20, which represents the largest module can establish communications satellites and 20 boards, 3 is a 2D satellite positioning data unstable module Only after three or more also receive satellite signals, after a complex operation to obtain the correct positioning data second-order circuit board, the more communications satellites if both the number of stars a special circuit boards, modules will be able to get faster the more accurate positioning data , usually 4 to 11 at the same time and at the same time satellite communications under the surface of the earth in general urban environment. Newell Shenzhen Electronic Technology Co., Ltd. how to do if there is a long time when you can not locate a cold start? Then you need to check whether the GPS antenna placement in an expansive environment, the ability to read the GPS data from the GPS module output? GPS data inside the GSV statements can be observed GPS satellite signal status? From these aspects can determine what specific issues! Modules can be output once per second: $ GPGGA $ GPGSA $ GPGSV $ GPRMC positioning data, we usually use $ GPRMC streamline data output this information, this information includes the target: longitude, latitude, speed (miles / hour), direction of motion angle, year, month, hours, minutes, seconds, milliseconds, location data is valid or invalid most of these chips is important information, GPS module or the use of global market share of the first series based Goldfinger circuit SiRFIII board, SiRFIII chip 20-channel, real-time solving ability. The market is a very common part of the module: ring days Gama, Ublox etc. GPS module circuit board circuit board _ _ hit the board by Newell Newell Shenzhen Electronic Technology Limited. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) strong, credible, in Shenzhen, Guangdong printed circuit board industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Newell invasive and you hand into the brilliant, for a better future!
