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. An improved SPI interface and register structure provide faster data col ection and configuration control. This compact module is approximately 44 mm × 47 mm × 14 mm and provides a flexible connector interface that enables multiple mounting orientation options.
