3DM-RTK Modem

The MicroStrain 3DM-RTK provides easy to use real time Kinematic (RTK) correction data to be utilized by the 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-GNSS/INS 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.
