The Astronautics 17595-3 Rate Gyro is an advanced inertial measurement unit (IMU) designed for precise attitude and angular rate measurement in aerospace applications. This gyro offers superior performance and reliability, making it an ideal choice for demanding space environments.
At the heart of this IMU is a high-precision, low-noise rate gyroscope. It employs a fiber optic gyro technology that provides very low noise levels and excellent stability. The gyro can measure angular rates in all three axes (roll, pitch, and yaw) with a measurement range of 150 degrees per second. The output signal is available in analog Volt per Volt (V/V) format with an adjustable gain to fine-tune the signal for specific requirements.
The 17595-3 Rate Gyro features temperature compensation, allowing it to function optimally in a wide temperature range of -15 C to 55 C. It also includes built-in self-test capabilities to ensure data accuracy and reliability.
The unit is compact and lightweight, with dimensions of 9.7 cm x 3.1 cm x 3.1 cm (3.8 in x 1.2 in x 1.2 in) and a weight of approximately 0.6 kg (1.3 lbs). It comes with an operating voltage range of 12 to 32 V DC, making it suitable for full-duplex communication interfaces, such as RS-422 or MIL-STD-1553.
The Astronautics 17595-3 Rate Gyro is housed in a rugged, hermetically sealed enclosure, conforming to MIL-STD-883 according to environmental conditions, such as temperature, vibration, and shock. The device is also qualified to the MIL-STD-1540E environmental standards for space applications.
As a complete attitude and angular rate measurement solution, the 17595-3 Rate Gyro can be integrated with a standards-compliant strapdown navigation system for spacecraft or UAV applications. With its superior performance, reliability, and extensive interface options, this gyro is the go-to choice for challenging aerospace projects that demand precise attitude and angular rate measurements.
