The 3DM-GQ7 GNSS-Aided INS is tactical-grade dual-antenna RTK GNSS/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. Cloud 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. Kalman filtering and

advanced sensor fusion, the GNSS/INS delivers highly accurate computed outputs under challenging real-world dynamic conditions.
