SDI500 Tactical Grade Inertial Measurement Unit (IMU) (Non-ITAR)

Compact, Rugged Tactical Grade MEMS Inertial Measurement Unit
Systron Donner Quartz MEMS
Leveraging industry’s leading MEMS technology to provide previously unheard of capabilities in angle random walk values (0.02°/√hr.) without loss of tactical grade levels across military environments, including 1°/hr. bias stability, the SDI500 is designed to achieve the demanding performance levels required in sophisticated systems applications. It is particularly suited for use by Integrators and OEMs, packaged in a highly miniaturized, cylindrical configuration with a volume of only 19 cubic inches. Boasting a 20-Year lifetime capability without requiring calibration and a MTBF of more than 25,000 hours, multiple output data formats and SDLC, RS232 and UART output interfaces are provided in this revolutionary IMU for optimized systems protocols.
