The MicroStrain 3DM-GQ7-GNSS/INS is a complete RTK enabled navigation solution featuring centimeter-level position accuracy.
The system includes dual multiband GNSS receivers, low-noise and low-drift MEMS inertial sensors, and a robust Adaptive Extended Kalman Filter (EKF).
MicroStrain sensors have set the standard for inertial sensor performance for over 20 years.
The 3DM-GQ7-GNSS/INS continues to build upon that legacy and includes a host of new features that ensure optimum performance in even the most demanding applications.
The MicroStrain 3DM-GQ7-GNSS/INS is an all-in-one navigation solution featuring centimeter-level position accuracy. It is our first dual-antenna, RTK enabled INS designed for outstanding performance, even in unpredictable conditions. It is equipped with dual multiband GNSS receivers, low noise and low drift MEMS inertial sensors, and a robust adaptive Kalman filter.
When paired with our 3DM-RTK Modem and SensorCloud RTK corrections service, the 3DM-GQ7-GNSS/INS is the best single-vendor RTK navigation solution available.
