Micro-Magic's Tactical MEMS IMU Sensor Achieves Full Compatibility with Industry Mainstream Solutions and Delivers a Performance Leap

Recently, Micro-Magic Inc officially launched a high-performance tactical grade MEMS inertial measurement unit (IMU) product - U5000, which is a benchmark for the well-known Sensonor STIM320 series products in the industry. This domestically produced IMU not only achieves benchmarking in core performance indicators, but also demonstrates good compatibility and upgrade potential in exterior structure, electrical interfaces, and other aspects, providing a new cost-effective choice for attitude perception and navigation applications in industrial, aerospace, unmanned systems and other fields

In terms of core performance indicators, U5000 demonstrates tactical level accuracy comparable to STIM320. Its gyroscope zero bias stability (Allen variance) reaches ≤ 0.1°/h, angle random walk ≤ 0.1°/√ h, accelerometer zero bias instability ≤ 30μg, overall stable and reliable performance, especially maintaining good compensation effect in the full temperature range (-40℃ to +80℃). U5000 supports a wide temperature range of -40℃ to +85℃ and has full temperature compensation, which can maintain stable output in complex environments. This product has high bandwidth (≥200Hz), good vibration and impact resistance, and demonstrates solid environmental adaptability.

In terms of external dimensions, weight, and structural design, the U5000 is comparable to the STIM/320. It employs a compact package design to align with the trend of miniaturization in modern equipment. The U5000 measures 44.8×38.6×21.5 mm and weighs approximately 52 grams. With a structurally reinforced design, it is well-suited for installation in high-dynamic or harsh environments. U5000 provides clear installation benchmarks and coordinate system definitions, supports standardized operations for mechanical fixation and electrical connections, and reduces the difficulty of system integration.

The data interface and communication protocol are the key to integrating IMU into the system. The U5000 is equipped with multiple communication interfaces, including RS232, RS422, as well as dedicated synchronization signals TOV and PPS inputs, supporting external GNSS receivers for time synchronization and data fusion. Its default output adopts 55AA frame format, with clear structure, complete verification, and supports user configuration of baud rate and output frequency, with strong compatibility.

From the perspective of application scenarios, U5000, with its higher precision sensing performance, is mainly targeted at fields that require extremely high measurement stability, such as satellite communication dynamic communication (SOTM), high-precision surveying and mapping systems, autonomous driving testing platforms, aviation navigation and stability control, etc.

The launch of U5000 marks that the company's high-performance MEMS IMU has the ability to benchmark with international mainstream products. Not only does it closely follow the STIM series in key performance parameters, but it has also been enhanced in interface flexibility, protocol openness, and other aspects, providing users with a solution with compatibility potential and more configuration freedom. With the continuous deepening of market applications, this product is expected to play an important role in unmanned systems, high-end equipment, autonomous navigation and other fields, promoting technological progress and cost optimization in related industries.
