The Astronautics 17595-5 Rate Gyro, a product of Astronautics Corporation of America, is a versatile and high-performance rotating rate gyroscope designed for use in aerospace applications. This gyroscope is designed to measure and provide precise angular rate information, making it an essential component for attitude determination and control systems in various aerospace platforms, including satellites, rockets, and unmanned aerospace vehicles.
The 17595-5 Rate Gyro features a rugged and compact design, with dimensions of 4.42 inches (11.2 cm) in length, 4.19 inches (10.6 cm) in width, and 2.5 inches (6.4 cm) in height. It is designed to operate in extreme environmental conditions, with a temperature range of -40 C to 85 C (-40 F to 185 F) and a vibration environment of 10 grms at 20 Hz.
The gyroscope utilizes a fiber optic ring laser gyro technology, which provides excellent stability, accuracy, and sensitivity. In particular, it offers a typical angular random walk of 0.01 degrees per hour, a bias stability of 0.01 degrees per hour, and a scale factor accuracy of 0.05%. With a measurement range of 250 degrees per second, it can precisely and accurately measure and report angular rates in all three axes: X, Y, and Z.
The 17595-5 Rate Gyro includes a built-in data output marginally, which provides analog outputs of angular rates in the form of voltage signals. Specifically, it offers both analog and digital output options: 0.1 mV/degree/second for analog outputs and 16-bit unsigned data (Burble Liner Protocol) for digital outputs. It also features a built-in self-test function, which allows for periodic checks of the gyro's performance and health.
The gyroscope is compatible with various aerospace platforms and systems, including MIL-STD-1553B, SpaceWire, and RS-422 interfaces. It can be easily installed and integrated into systems with minimal mechanical modifications due to its standardized 1.27 inch (32.26 mm) diameter flange mounting.
Overall, the Astronautics 17595-5 Rate Gyro is a high-precision, versatile, and reliable angular rate measurement solution for aerospace applications. Its rugged design, superior technology, and multiple output options make it an ideal choice for maintaining the stability and control of aerospace platforms in dynamic environments.
