Introduction
TDMS-100MEMS Integrated navigation system is a highly reliable and cost-effective six-axis MEMS inertial/satellite integrated navigation system, which can be widely used in the navigation, control and measurement fields represented by UAVS. The TDMS-100 integrated navigation system is mainly composed of three-axis MEMS gyroscope, three-axis MEMS accelerometer, information processing circuit, navigation software, structural components, test cables, test software, and dual-antenna GNSS receiver (built-in).
The TDMS-100 MEMS series integrated navigation system integrates high-performance MEMS gyroscopes and MEMS accelerometers in a separate structure. The gyroscopes and accelerometers selected for the system represent the leading level of MEMS inertial devices. The zero bias of all temperature parameters, scale factor, non-orthogonal error and acceleration related terms are compensated in the system, which can maintain high measurement accuracy for a long time. At the same time, auto-adaptive attitude algorithm is integrated in the system, which can ensure the measurement accuracy of attitude for a long time.
The following outputs are provided by default: 3D angular velocity, 3D acceleration, gyro temperature, accelerometer temperature, 3D attitude, INS/GNSS position, INS/GNSS speed.
