GSTIM300 Military-Grade MEMS IMU
GSTIM300 delivers 0.5°/h gyro bias stability in a MEMS design that meets general military standards. RS-422 interface supports 500Hz high-speed data output, while 5000g shock tolerance and -45°C to +85°C operation ensure survival in extreme environments. Integrated attitude solving (pitch/roll) reduces external processing needs. M4 screw mounting provides secure mechanical integration for guided weaponry, aviation stabilization, and dynamic measurement tasks.

Product Introduction
The GSTIM300 is a high performance, small size and high overload resistant inertial measurement device for precise navigation, control and dynamic measurement of weapons. This series of products uses full MEMS inertial devices.
Power supply, ADC, processor, interface chip are purchased. The overall performance of the product reaches the common military standard.
GSTIM300 is composed of a three-axis gyroscope, a three-axis accelerometer, a temperature sensor, a signal processing board, a structure and necessary software, which is used to measure the three-axis angular rate, three-axis acceleration, pitch and roll Angle of the carrier.
Through RS-422 serial port according to the convention communication protocol output error compensation (including temperature compensation, installation misalignment Angle compensation, nonlinear compensation, etc.) gyroscope, accelerometer and pitch, roll Angle.

Figure 4 Appearance of the IMU
The GSTIM300 is installed with three Φ4.4 through holes and three M4 screws (spring washer and flat washer). When the connector is installed, the plug should be locked with the socket and the cable should be fixed. It is recommended that the flatness and verticality of the installation surface relative to the base plane be no more than 0.02mm, no more than 0.04mm, and no more than 0.8μm of the surface roughness
