I6700 MEMS High Precision Integrated INS/GNSS Navigation System RTK Dual Antenna 200Hz Output 9-36V ≤4W
The I6700 series MEMS integrated navigation system is a high-precision, high-reliability, and cost-effective MEMS inertial integrated navigation system, which can be widely used in navigation, control, and measurement fields represented by vehicles, ships, and drones.
The I6700 series integrated navigation system integrates high-performance MEMS gyroscopes, MEMS accelerometers, and GNSS satellite receiver chips. By sensing the Earth's rotation angular rate and acceleration, it achieves true heading of the current carrier's motion through static self-alignment, and integrates with the three-dimensional velocity, position, and heading obtained from the satellite GNSS receiver for integrated navigation. The integrated navigation system performs temperature drift of zero bias compensation and full-temperature scale compensation on the internal IMU module to ensure product reliability.
The product offers various configuration modes to accommodate different carriers, such as airborne, vehicular, and shipborne. Appropriate scenario modes help ensure long-term measurement accuracy of the carrier's attitude.
