In order to achieve the vehicle navigation, vehicle intercept terminal equipment and portable terminal equipment positioning module requirements for use, Junoda product development and release of embedded GNSS positioning module is divided into a single GNSS positioning module and GNSS antenna integration module. This JUNODA will provide you with a detailed introduction to the MT3331 program according to the industrial production level small size GNSS antenna integration module ST-28-M3G.
Industrial production grade small size GNSS module ST-28-M3G
ST-28-M3G is an integrated porcelain antenna GNSS antenna integrated positioning module, with ultra-high sensitivity, ultra-low power consumption and small-size features. ST-28-M3G antenna accepts positioning information content from communication satellites, and according to the nmea protocol or serial communication customization protocol, it will record the site, rate, and inter-temporal information information and other serial communication data information in detail. The SST-28-M3G can record the location, rate and time information in detail according to the nmea protocol or serial communication customization protocol.
SST-28-M3G is constructed according to MT3331soc chip with excellent performance characteristics, -165dBm high tracking sensitivity, which makes it possible to locate the position in the harsh environment such as the big city canyon, the shade of the green, and the overpass! Strong anti-interference, multi-system software contact positioning and excellent porcelain antenna characteristics of the advantages of the characteristics of the Internet of Things technology intelligent transportation, car navigation, intelligent transportation, intelligent security and other aspects of the multi-mode fiber positioning requirements.
Operating temperature range of -40 ~ 85 ℃, even if the very extreme outdoor natural environment can also be instant output specification of high-precision location information; 18 * 18 (mm) small specification highly integrated packaging characteristics make the module easy to integrate into the PND, cell phones, cameras and car site navigation and other portable devices.
Eventually, I talked about: in the whole process of commodity road test, only must be connected to the TXD, RXD, VCC, GND these four sockets can be, the detection process can not be casually move the module.
At this stage Junoda industrial production level small specification GNSS antenna integration module ST-28-M3G has been widely used in LBS (according to the local service program), PND (portable navigation bar machine equipment), car navigation system software and other positioning terminal equipment.
