MEMS IMU & GPS/INS
TAC-440 Quartz MEMS Tactical Grade IMU
The NEW TAC-440 MEMS Inertial Measurement Unit (IMU) is the world’s smallest 1°/hour IMU.
Featuring an ultra-compact package of less than 5 cubic inches, the TAC-440 is a higher-perfor-
mance, form, fit, and function compatible replacement for the Honeywell 1930 and 4930 IMUs. The
TAC-440 features 1°/hour gyro bias and 1 mg accelerometer bias stability with very low 0.05°/√hour
Angle Random Walk (ARW) over a wide temperature range. It delivers outstanding performance
over temperature, shock, and vibration environments with a Velocity Random Walk (VRW) rating of
32 μg/√Hz.

SDN500 Quartz MEMS GPS/INS Tactical Grade Navigation System
Our most advanced MEMS GPS/INS tactical grade system, the compact SDN500 combines latest
generation quartz gyros, quartz accelerometers, high-speed signal processing, and a 48-chan-
nel Coarse/Acquisition (C/A) code GPS receiver into a powerful, tightly coupled guidance and
navigation system. There is also an option to utilize a Selective Availability Anti-Spoofing Module
(SAASM) GPS receiver. Our proprietary quartz MEMS inertial sensors maintain position and
attitude accuracy in the event of loss of GPS tracking. The low-power SDN500 is designed for
integrator and OEM use in the latest demanding, smaller, and more scalable system applications.
