MicroStrain by HBK GNSS Inertial Navigation Systems (INS)

MicroStrain by HBK GNSS Inertial Navigation Systems (INS) are an all-in-one navigation solution with centimeter-level position accuracy. The 3DMGQ7 is a dual-antenna, RTK-enabled INS designed for performance in unpredictable conditions. It's equipped with dual multiband GNSS receivers, low noise and low drift MEMS inertial sensors, and a robust adaptive Kalman filter. Pair with the 3DMRTK Modem and SensorCloud RTK corrections service for a single-vendor RTK navigation solution.
