Introduction
HS-AHRS-901 attitude sensor is a inertial measurement system with high precision based on MEMS inertial sensing devices, with built-in accelerometer, fluxgate sensor and gyroscope. The system contains temperature correction and non orthogonal error compensation algorithms, which can accurately output the carrier's three attitude angles (pitch angle, roll angle and heading angle) and other auxiliary sensing signals (acceleration and angular velocity) in a dynamic environment.
Features
Course keeping under magnetic field interferenceenvironment;
High speed data output;
High reliability, waterproof, shockproof, anti electromagnetic interference, no pollution
Application
Widely used in aviation, aerospace and other fields, and in products and equipment such as UAV, unmanned driving, ship etc.
