(USB / Bluetooth BLE dual interfaces, GPS and QZSS multiple constellations, Windows, Android and IOS compatible)
Compared to the GT-120 GPS, GT-120B is now a GNSS. It supports both GPS and QZSS constellations. It has Indoor and outdoor multi-path detection and compensation which dramatically eliminates Ionospheric error and multi-path effects. Data accuracy is getting improved.
GT-120B has usb and bluetooth BLE dual interfaces. Data can be downloaded via either usb or bluetooth BLE. Instead of the proprietary USB cable for GT-120, GT-120B now uses a standard micros-usb cable.
GT-120B can be used as an usb GNSS receiver with 1-10Hz update rates. When used as a GNSS data logger, the update rate is 1 Hz.
