Geo Week 2023 & Oceanology International Americas 2023

Fizoptika Malta is presenting its newest inertial products – the smallest fiber optic gyroscope VG221 and miniature FOG-based inertial measurement units (FOG IMUs) at Geo Week (February 13-15, Denver, USA, Booth 1050) and Oceanology International Americas (February 14-16, San Diego, USA, Booth E19). 

The fiber optic gyro VG221 is a revolutionary small and lightweight sensor with ultra-low power consumption – measuring  just ∅33×12 mm, weighing 15 g,  consuming 0.3 Watt. The VG221 has two new variants – VG221MS (magnetically shielded case) and VG221LN (low noise performance).

Our latest FOG IMUs are based on three VG221-like sensors and have been developed to satisfy growing market demand for low SWaP (size, weight and power) inertial products for autonomous and unmanned systems. The units are well-suited for inertial navigation systems (INSs) in drones / UUVs / USVs / ROVs.

The FOG IMU U121D is housed in a compact Al enclosure (63x56x40 mm) and consumes just 1.5 Watt of power. It features bias of 3°/h and ARW of 0.05°/√h.

The FOG IMU U123D has an ultra-compact cylindrical design (∅40×100 mm) and delivers low noise performance with 1°/h bias and 0.05°/√h ARW. The unit has very low power consumption of 1.5 Watt, too.
