(USB / Wireless dual interfaces, GPS and QZSS multiple constellations, Windows, Android and IOS compatible)
Compared to previous models (i.e. GT 120) which are GPS, GT-120B is a GNSS logger that utilizes both GPS and QZSS constellations. It has multi-path detection, which dramatically eliminates Ionospheric error and multi-path effects. Compared to previous GPS models, the data accuracy is significantly better.
GT-120B has usb and wireless dual interfaces, which allows data to be downloaded either via either usb or wirelessly. Rather than using the proprietary USB cable for GT-120, GT-120B 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.
Managing large deployments of GT-120B with ease
The I-gotU GT-120B comes with mobile and Windows apps which help manage a large number of loggers.
1. You can view all your GT-120B devices on Google maps from your mobile phone app.
2. You can self define a group, add loggers to the group and select tracks from the group.
3. From your mobile phone, you can keep track of battery and memory statuses of all your GT-120B devices.
4. Not only can you backup your device settings, you can also standardize the settings of a bunch of devices by using import / export features.
5. If you want to protect the GT-120B data from unauthorized downloads, you can enable password check settings.
6. GT-120B can be turned on / off by a predefined schedule.
