FOG & MEMS INS Z-axis bias stability ≤0.03°/h
X/Y axis MEMS, Z axis FOG, accelerometer, GNSS equipped, compact and lightweight 500g, ideal for autonomous driving and underground navigation systems.
This INS utilizes inexpensive MEMS for the X-axis (Roll) and Y-axis (Pitch), and a self-developed FOG for the Z-axis (Yaw), achieving high precision while keeping costs down. The bias stability is <10°/h for the X and Y axes, and <0.03°/h for the Z axis. We also offer a budget version with the Z-axis at <0.2°/h. It includes a GNSS module with RTK positioning capabilities and a speedometer, enabling advanced navigation. Temperature compensation is applied across the entire operating temperature range, allowing real-time output of position, velocity, and attitude states with centimeter-level accuracy, and it can maintain functionality for a while even after losing satellite signals. The design complies with automotive regulations, employs navigation algorithms that recognize the vehicle's motion state, supports connections with multiple sensors, offers online software upgrade capabilities, and features automatic parameter calibration. It is ideal for Level 4 autonomous driving vehicles, unmanned operation of construction machinery, cranes, and agricultural machinery, mobile mapping, and navigation systems in underground parking lots, tunnels, and other areas where satellite signals are unavailable.
