QU8M is a multimode USB GNSS receiver with built-in ubx neo-m8n module (M8030 chip) and built-in 4M flash to support configuration and permanent saving of configuration. The UBX-M8030 high performance standard precision GNSS chips from u-blox provide exceptional sensitivity and acquisition times for all GNSS systems. The chips utilize concurrent reception of up to three GNSS systems (GPS/Galileo together with either Beidou or GLONASS). Reception from more than one constellation simultaneously allows extraordinary positioning accuracy in urban canyons, even with weak signals and high dynamics. ​The accuracy reaches 1.5m cep，and the average cold start time is 26s.It also has built-in small battery to support receiver hot start.It is widely used in PC navigation, car navigation, marine navigation, ranging, automatic driving travel, fleet management, vehicle tracking, etc. It supports Google Earth, and the external GPS receiver cooperates with Google Earth for precise positioning.This product supports Android 4.1 and above systems, download the APP(GPS Connector.APK)for Android systems, and set mock location.Get more accurate positioning for your Android smart device！ ​Highlights: ​• Concurrent reception of up to 3 GNSS (GPS, Galileo, GLONASS, BeiDou) ​• Industry leading -167 dBm navigation sensitivity ​• Industry lowest current consumption ​• Superior position accuracy in urban canyons ​• Security and integrity protection ​• Support for all satellite augmentation systems
