CSTR-GYR1200 is a high-end tactical class gyro module consisting of a high-performance triaxial gyroscope sensor based on the latest MEMS technology. The GYR1200 communicates via a standard high-level RS422 interface, and the unit runs off a single +5V supply. The GYR1200 is successfully qualified for high mechanical shock environments of up to 1500 g & in thermal cycling from -40°C to +85°C.

 

The CASTOR series model CSTR-GYR1200 is a high-end tactical class gyro module consisting of a high-performance triaxial gyroscope sensor based on the latest MEMS technology. This is equipped with a high-speed processor that runs the digital signal processing algorithms, delivering control-grade inertial measurement data. The gyro module output is available over an RS422 interface. Its rugged and modular design makes it suitable for integration with control computers and other application hardware.

 

The sensing elements of each axis are factory-calibrated for bias and misalignment and are compensated for temperature effects to be usable across the entire operating temperature range. The miniature gyro module, CSTR-GYR1200, offers 0.6°/hr bias instability performance and is suitable for inertial guidance and control applications where size is the constraint. 

Product Features

Q & A

What is the default baud rate for communication in CSTR-GYR1200?

The default baud rate for communication in CSTR-GYR1200 is 460800.

What is the operating voltage for CSTR-GYR1200?

The typical operating voltage for CSTR-GYR1200 is +5V DC.

Is the CSTR-GYR1200 temperature calibrated?

Yes, the CSTR-GYR1200 is temperature calibrated.

Can external trigger frequency be 2000Hz?

No, the external trigger frequency cannot be 2000Hz as it will affect the internal sampling. It is suggested to use external trigger frequency less than 125Hz.

Can we use TOV signal to measure the sample rate?

Yes, since every low to high transition of TOV signal represents the data output.
