In general, inertial sensors can be divided into performance categories based on bias stability specifications, which help classify the performance of the module. The higher the grade of the sensor, the higher its accuracy tends to be. Typically, tactical-grade and industrial-grade IMUs are the first choice for demanding applications such as drone navigation because they offer high performance and accuracy. Tactical-grade IMUs operate gyroscopes with extremely low bias stability, which means that the bias error becomes more stable over time. This is a necessary quality for mission-critical and high-precision applications such as drone navigation, antenna and weapon platform stabilization. ER-MIMU02 and ER-MIMU06 developed by Ericco are tactical-grade IMUs. They use high-quality and reliable MEMS accelerometers and gyroscopes. RS422 communicates with the outside. The baud rate can be flexibly set between 9600~921600. Users can set it through the communication protocol. The desired communication baud rate. Equipped with X, Y, Z three-axis precision gyroscope, X, Y, Z three-axis accelerometer, with high resolution, it can output the original hexadecimal complement of X, Y, Z three-axis gyroscope and accelerometer through RS422 code data (including gyroscope hexadecimal complement) numerical temperature, angle, accelerometer hexadecimal temperature, acceleration hexadecimal complement); it can also output gyroscope and accelerometer data that have been processed by underlying calculations Floating point dimensionless value. Industrial-grade IMUs are less accurate than tactical-grade IMUs, but have better performance and reliability than systems for consumer applications.
They have good resistance to shock and vibration and exhibit good repeatability over time and temperature. Many industrial grade IMUs are factory calibrated for improved temperature performance.
MEMS-based IMUs are often used in industrial-grade applications such as drone platforms that require small components over other performance parameters for stability, control, and navigation.
In addition to industrial and tactical grade IMUs, higher grade IMUs are also available: navigation grade, strategic grade or military grade.
Drone IMUs often need to be highly rugged to withstand harsh environments, such as high levels of shock and vibration and wide temperature ranges. Housings can be made from materials such as precision machined anodized aluminum and meet various ingress protection (environmental sealing) standards, and IMUs with low vibration sensitivity provide higher accuracy navigation solutions in harsh drone applications with high vibration levels plan.
