SI‑MINS200S MEMS INS | Lightweight ≤0.6kg, High-Reliability for Unmanned Vehicle Navigation
This new‑generation MEMS inertial/satellite integrated navigation system integrates a high‑precision survey‑grade satellite receiver board, three‑axis MEMS gyroscopes, and three‑axis MEMS accelerometers. It delivers centimeter‑level positioning accuracy under favorable satellite signal conditions and sustains long-term stable output of precise position, velocity and attitude data.
Featuring a lightweight, compact and easy‑to‑integrate design, the system is widely applicable to assisted driving, autonomous vehicles, vehicle positioning and orientation, AGV robots, power line inspection, platform stabilization, surveying and mapping, and precision agriculture scenarios.
