Trimble R1

Professional-level GNSS positioning information from almost any device

Accuracy for everyone

The Trimble R1 is a rugged, pocket-sized GNSS receiver that provides sub-meter precision to users of any Bluetooth connected mobile device, including smartphones, tablets, or more traditional integrated data collection tools such as a Trimble handheld computer.

Multiple Constellation Support Provides Global Reach.

The R1 supports multiple GNSS constellations, including GPS, GLONASS, Galileo ,QZSS and BeiDou, to provide a truly global solution. The R1 receiver includes the ability to utilize Satellite Based Augmentation Services (SBAS), Trimble ViewPointTM RTX or, Virtual Reference Station (VRS) correction sources to suit the location and business requirements - providing accurate GNSS information almost anywhere on earth
