It integrates an accelerometer, gyroscope, and attitude solver with Kalman filtering for stable, high-precision angle output, and (on GPS versions) reports latitude\/longitude and ground speed. Housing is aluminum with IP67 dust\/water protection, an external antenna interface, and a shielded cable for robust signal integrity. PC software and sample code (Windows C\/C#, STM32, 51, MATLAB) are provided for rapid integration.\u003c\/p\u003e\n\u003cp data-start=\"723\" data-end=\"743\"\u003e\u003cstrong data-start=\"723\" data-end=\"743\"\u003eCore performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"744\" data-end=\"1320\"\u003e\n\u003cli data-start=\"744\" data-end=\"809\"\u003e\n\u003cp data-start=\"746\" data-end=\"809\"\u003e\u003cstrong data-start=\"746\" data-end=\"768\"\u003eAttitude accuracy:\u003c\/strong\u003e static 0.05°, dynamic 0.1° (series spec)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"810\" data-end=\"879\"\u003e\n\u003cp data-start=\"812\" data-end=\"879\"\u003e\u003cstrong data-start=\"812\" data-end=\"826\"\u003eIMU range:\u003c\/strong\u003e acceleration ±16 g;
