MicroStrain 3DM-RTK Network Interface Modem, Industrial Package

The MicroStrain 3DM-RTK provides easy to use real time Kinematic (RTK) correction data to be utilized by the MicroStrain 3DM-GQ7-GNSS/INS. It provides the simplicity of a cellular connection to our SensorCloud RTK base station network, replacing traditional radio-based stations. With RTK corrections the 3DM-GQ7 can achieve centimeter-level positional accuracy. By removing the need for a base station infrastructure the 3DM-RTK is the quickest and most efficient to market solution.

The 3DM-GQ7-GNSS/INS sensor combined with the 3DM-RTK modem delivers accurate positioning, velocity, and attitude estimates at 1kHz. This industry-leading performance incorporates less than 2 cm accuracy, 0.05 m/s velocity accuracy, 0.1 degree roll/pitch accuracy, and 0.25 heading accuracy with a dual-antenna GNSS.
