Fizoptika Malta will be showcasing its latest inertial products at Oceanology International 2024, including small fiber optic gyroscopes (FOGs), high-precision FOGs, ultra-compact three-axis FOGs,  miniature FOG-based inertial measurement units (FOG IMUs), and more.

The 2024 Oceanology International event is being held in London, UK, from March 12-14, with Fizoptika Malta showcasing at Booth A203.

Among the company’s technology on show will be the fiber optic gyro VG221, a small, lightweight sensor with ultra-low power consumption – measuring just ∅33×12mm, weighing 15g, and consuming 0.3W. It features low noise performance with 0.05°/√h ARW (angle random walk) and a bias stability of 1°/h. 

The fiber optic gyro VG1703SPE is another of Fizoptika Malta’s sensors, offering a combination of a very small (∅40x12mm), lightweight (18g) design and super low power consumption of 0.25W. It features low noise performance with 0.025°/√h ARW and a bias stability of 1°/h.

At the other end of the form-factor scale is the company’s bigger fiber optic gyro VG035LND, which delivers impressive performance with 0.0015 °/√h ARW and a bias stability of 0.03 °/h. The FOG sensor offers magnetic immunity due to its built-in magnetic shield.

Fizoptika Malta will also present its triple-axis fiber optic gyroscopes, which offer low noise performance in ultra-compact and lightweight units with low power consumption of 2W.

The G181 is a cylinder-shaped unit measuring ∅46x111mm and weighing 160g. This 3-axis gyro delivers excellent performance with 0.015°/√h ARW and a bias stability of 1°/h. 

The three-axis fiber optic gyroscopes G121 feature a compact footprint of 52x58mm and light weight of 125g. These SWaP parameters are combined with low noise performance of 0.025°/√h ARW and a bias stability of 1°/h. 

Additionally, the company will be displaying a range of newly-developed FOG-based inertial measurement units (FOG IMUs). They combine its smallest fiber optic gyroscopes and MEMS accelerometers.

The FOG IMU U121D is housed in a compact Al case (63x56x40mm) and consumes just 1.5W 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 1.5W, too. 

Another FOG IMU with a cylindrical form-factor is the U183(M). It is 46mm in diameter and weighs 200g. The unit consumes as low as 2W, and features 0.03 °/√h ARW, 1°/h bias stability.

Fizoptika Malta’s inertial sensors are designed to suit various space- and layout-limited applications including inertial navigation systems (INSs) in UAVs, UUVs, USVs, and ROVs.
