Systron Donner Inertial to Provide IMU for BAE Spearfish Torpedo

Published: 14 Aug 2015

Systron Donner Inertial IMUSystron Donner Inertial (SDI), a supplier of inertial sensing products, has announced that it has been awarded a contract by BAE Systems for an Inertial Measurement Unit (IMU) integral to the Guidance and Control Assembly (G&C) required for the Spearfish Heavyweight Torpedo Program.

The core of SDI’s solution is its SDI500 IMU, delivering tactical grade performance with <1º/hr. bias stability across full temperature, 0.02º/√hr. angle random walk and 1 mg accelerometer bias performance. The compact, low power, high quality SDI500 IMU enables superior guidance and control of the Spearfish Torpedo during in-water maneuvers, plus improved system cost-effectiveness, reduced obsolescence and increased sustainability for BAE Systems.

“SDI is honored to be selected as part of the Spearfish Torpedo Program,” said David Hoyh, Director Sales & Marketing for SDI. “On June 9, 2015 SDI delivered the 1,000th SDI500 tactical grade IMU. Now customers worldwide are experiencing the superior inertial bias and low noise performance benefits of the Quartz MEMS IMU, in a smaller, lighter, more reliable, cost-effective product than traditional tactical grade technologies.”
