Product Description
Main features Potting design, high reliability High performance, small size Light weight, low power consumption -40ºC to +80ºC full temperature calibration compensation 1KHz high-speed sampling Strong anti-overload ability of the system With software online upgrade function
Application area Low-precision heading and attitude Individual rockets Cannon-launched missiles Smart ammunition AGV trolley Low-precision surveying and mapping Stability control AR/VR helmet Drone Unmanned vehicles Unmanned shipAdvanced manufacturing processThe OEHG101 MEMS inertial measurement unit integrates a high-performance MEMS gyroscope and MEMS accelerometer in an independent structure. The gyroscope and accelerometer selected by the module represent the leading level of MEMS process inertial devices. The module internally compensates for the zero position of the full temperature parameter, scale factor, non-orthogonal error and acceleration-related items, which can maintain high measurement accuracy for a long time. At the same time, the internal chip of the module adopts vacuum-level packaging, integral potting and other measures to ensure that the product can still accurately measure the angular and linear motion parameters of the carrier in harsh environments, thus providing users with a low-cost and high-reliability solution .
Batch calibration and compensation technologyIn view of the large-volume and low-cost characteristics of this product, the company adopts mass-production and automated calibration and compensation technology in the production process of the product, and the fault diagnosis and removal technology in the mass-manufacturing process not only maintains excellent performance, but also It can ensure that the product has an annual production capacity of 10,000 sets.Table 1.
