Description
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.
