3DM-GQ7 Documentation Center

Product Description

The 3DM-GQ7 is a high-performance, tactical-grade GNSS-Aided Inertial Navigation System(GNSS/INS) that combines MEMS inertial sensors with dual multi-frequency GNSS receivers for use in a wide range of applications. Common use cases include unmanned vehicle navigation, robotic control, platform stabilization, motion tracking and analysis, vehicle health monitoring, and device aiming.
