MostaTech will present its advanced fiber optic gyroscopes (FOGs), FOG-based inertial measurement units (IMUs), and inertial sensors at Joint Navigation Conference (JNC) 2025, taking place June 3-4 in Greater Cincinnati, USA.
Visitors to Booth #333 can discover the latest addition to the company’s line of compact three-axis FOGs: the G321, featuring a high-speed data output.
MostaTech will present its cutting-edge IMUs, which combine miniature FOGs with MEMS accelerometers. These IMUs are designed to meet the industry’s demand for low-SWaP (size, weight, and power) solutions, ensuring high performance in space- and layout-limited applications.
FOG IMU U121D

Key Features include:
- Compact Design: Housed in an aluminum case measuring 63x56x40mm.
- Lightweight: Weighs 195 grams.
- Energy Efficient: Consumes just 1.5W of power.
- Low Noise Performance: Offers a bias stability of 1°/h and an ARW of 0.05°/√h.
- Advanced Magnetic Immunity: Provides enhanced accuracy in challenging environments.
FOG IMU U123D
Key Features include:
- Cylindrical Form Factor: Measures ∅40x90mm.
- Lightweight: Weighs 150 grams.
- Low Power Consumption: Consumes only 1.5W of power.
- Low Noise Performance: Features a bias stability of 1°/h and an ARW of 0.05°/√h.
- Enhanced Magnetic Shielding: Ensures reliable operation in environments with high magnetic interference.
G321M FOG
The G321M is a MostaTech’s newest 3-axis FOG which integrates three smallest single-axis fiber optic gyroscopes with an advanced ADC board.
Key features include:
- Compact Size: Measures 53x53x36mm.
- Lightweight: Weighs only 145 grams.
- High Data Output: Delivers an impressive 8kHz data output rate.
- Low Noise Performance: Offers a bias stability of 1°/h and an ARW of 0.025°/√h.
- Advanced Magnetic Shielding: Ensures reliable operation in environments with high magnetic interference.
- Energy Efficient: Consumes just 2W of power.
These IMUs and triple-axis FOG complement MostaTech’s portfolio of miniature fiber optic gyroscopes and are designed to provide cost-effective, non-ITAR solutions for demanding applications including inertial navigation systems (INS) in UAVs, UUVs, USVs, ROVs, and gimbal/camera stabilization systems.
