The High Performance Technically Mature SDI500 Tactical Grade Quartz MEMS IMU Selected for Two Weapons Programs

Systron Donner Inertial (SDI), a brand of Custom Sensors & Technologies (CST), has recently been awarded two Inertial Measurement Unit (IMU) contacts in support of separate US Defense Weapons Programs.  SDI’s versatile Tactical Grade IMU is the first and only MEMS-based IMU to provide Guidance and Control Assembly (G&C) solutions for a Lightweight Torpedo and Long Range Missile Program.

The core of SDI’s solution is its COTS SDI500, the industry’s first and only MEMS-based IMU to deliver true tactical grade performance with 1º/hr. gyro bias across full temperature, class-leading 0.02º/√hr. angle random walk, solid < 1°/hr. in-run gyro bias and 1 mg accelerometer bias performance.  The compact, low power, high quality SDI500 satisfied the stringent guidance and control requirements better than any other IMU in the market today.

“SDI is thrilled and honored to be selected these weapons programs," said David Hoyh, Director Sales & Marketing for SDI.  “SDI’s mission for its maturing line of tactical grade products is to deliver superior full temperature inertial bias and noise performance in smaller, lighter, more reliable, cost-effective product solutions than traditional tactical grade technologies.”
