Autonomous Grade, Six Degrees of Freedom Inertial Sensor

The ADIS17555 is a complete inertial system that includes a triaxis gyroscope and a triaxis accelerometer. Each inertial sensor in the ADIS17555 combines industry leading MEMS only technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, and alignment. As a result, each sensor has its own dynamic compensation formulas that provide accurate sensor measurements.

The ADIS17555 provides a simple, cost-effective method for integrating accurate, multiaxis inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. Tight orthogonal alignment simplifies inertial frame alignment in navigation systems. The serial peripheral interface (SPI) and register structure provide a simple interface for data collection and configuration control.

The footprint and connector system of the ADIS17555 enable a simple upgrade from the ADIS16485, ADIS16488A, ADIS16490, ADIS16495, and ADIS16497. The ADIS17555 is available in an aluminum package that is approximately 47 mm × 44 mm × 15 mm and includes a standard connector interface.
