Product Introduction
The INS300E integrated navigation system consists of a MEMS three-axis gyroscope, a three-axis accelerometer, and a built-in GNSS receiver. The inertial sensors have undergone full-temperature-range calibration to meet performance requirements under various conditions. By integrating data from the inertial sensors and the GNSS receiver via a built-in processor, the system provides rich navigation information, including carrier attitude, heading, position, velocity, time, angular rate, and linear acceleration data. This product boasts advantages such as small size, low power consumption, high reliability, and stable performance. It can be widely applied in fields such as precision agriculture, autonomous vehicles, and mobile communication systems.
