Attitude sensor
Product Model:
MNS301E
Product Introduction
The MNS301E attitude sensor consists of a MEMS three‑axis gyroscope and a three‑axis accelerometer. After full‑temperature range calibration, the inertial sensors can meet performance requirements under various conditions. The product leverages a unique built‑in attitude algorithm to provide carriers with stable and reliable attitude information, as well as angular rate and linear acceleration data. It boasts advantages such as small size, low power consumption, high reliability, and stable performance. This product is suitable for attitude control in applications including vehicle-mounted, airborne, and shipborne systems.
