High sampling rate IMU with dual band GNSS receiver

The paper represents and discusses the high sampling rate 10DoF IMU system based on MEMS inertial MPU9250 sensor and atmospheric pressure sensor BMP280 and dual band GNSS receiver with improved accuracy, which is capable to measure and write the inertial and navigation information in the local storage (micro SD card). The system also is designed to communicate with the external serial communication devices (GSM/GPRS modems, Bluetooth, Zigbee, etc. modules) to send this information to the remote devices. It may accept the signal from external rotation encoder to accomplish the space sampling technique instead of the time sampling one. It is designed to be implemented in the transportation systems to measure the dynamic response of the vehicle-road interaction with high sampling rate and better position accuracy.
