MG2820 Series is a Quad-band GSM/GPRS module solution utilizes cocurrent reception of GNSS Systems(BDS/GPS/GLONASS/GALILEO) in a LCC type which embedded various network protocols TCP/UDP/PPP/HTTP/FTP/PING/NTP/NITZ/SSL. Featuring the tiny size and low power consumption, it offers accurate GNSS and wireless comunication function
MG2820 series has three types that respectively support centimeter, sub-meter and meter level position. MG2280 features superior performance of precision GNSS engine,supporting RTK single base and RTK based on CORS network position.It provides message integrity protection while featuring precision position which is more competitive than traditional GPS module. MG2820 is widely used in areas like shairing industry,wearable,telematics and wireless payment etc.
