MostaTech is set to present its latest generation of Fiber Optic Gyroscopes (FOGs) and FOG-based Inertial Measurement Units (FOG IMUs) at the Joint Navigation Conference (JNC) 2026 in Covington, Greater Cincinnati, USA at Booth #432.
The company’s SWaP-optimized FOG-based IMUs combine miniature optical gyroscopes with MEMS accelerometers to deliver stable inertial performance in compact, low-power packages. Among the featured products are the U121D, measuring 63×56 mm and weighing 180 g, and the cylindrical U123D, which measures ∅40×90 mm and weighs 150 g.
Both units operate at 1.5 W and provide 1°/h bias stability with 0.05°/√h angular random walk. To facilitate integration, a six-channel ADC board with RS422 output enables direct interfacing with navigation and control systems, while integrated magnetic shielding ensures consistent performance in electromagnetically disturbed environments. These units are designed for inertial navigation systems (INS) deployed across UAVs, UGVs, USVs, subsea platforms, and other mission-critical applications.
In addition to the IMUs, MostaTech will present the G321M, a compact three-axis fiber optic gyroscope designed for synchronized multi-axis sensing in demanding applications. Featuring a 53×53 mm footprint, a weight of 145 g, and 2 W power consumption, the G321M delivers high-rate data output up to 8 kHz via RS422. Its performance characteristics include 1°/h bias stability and 0.025°/√h ARW, supporting precise motion tracking and control in dynamic conditions. Like the IMUs, the G321M includes integrated magnetic shielding to enhance resilience in environments with high magnetic interference.
These systems are part of a wider MostaTech portfolio spanning ultra-miniature to rugged single-axis FOGs, enabling flexible sensor selection across a broad range of performance and mechanical requirements. Designed as cost-effective, non-ITAR solutions, MostaTech inertial sensors support applications such as inertial navigation systems (INS), unmanned aerial, ground and marine platforms, and stabilization systems for imaging and payload control. Attendees are invited to visit booth #432 to speak with the team.
