3DMGQ7 GNSS-Aided INS

The 3DMGQ7 GNSS/INS is a powerful tactical-grade navigation solution featuring low-noise and low-drift MEMS inertial sensors and dual-antenna RTK-capable GNSS receivers. It can be paired with the SensorCloud RTK corrections service for centimeter-level accuracy and superior performance even in the most challenging of conditions.

All sensors are fully calibrated, temperature-compensated, and mathematically-aligned to an orthogonal coordinate system. Thanks to sophisticated auto-adaptive Extended Kalman filtering and advanced sensor fusion, the GNSS/INS delivers highly accurate computed outputs under challenging real-world dynamic conditions.
