Oceanology International 2024 | 12-14 March | London, UK

Fizoptika Malta gyros and IMUs at Oceanology International London 2024

Fizoptika Malta will be showcasing its latest inertial products – the smallest fiber optic gyroscopes (FOGs), highly-precision FOGs, ultra-compact three-axis FOGs, miniature FOG-based inertial measurement units (FOG IMUs) at Oceanology International London (March 12-14, London, UK, Booth A203). 

The fiber optic gyro VG221 is a revolutionary small and lightweight sensor with an ultra-low power consumption – measuring just ∅33×12 mm, weighing 15 gr, and consuming 0.3 Watt. 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 sensor offering a combination of a very small (∅40x12mm), lightweight (18 gr) design and super low power consumption of 0.25 Watt. 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 our bigger fiber optic gyro VG035LND which delivers outstanding performance with 0.0015 °/√h ARW and a bias stability of 0.03 °/h. The FOG sensor offers ultimate magnetic immunity due to its built-in magnetic shield.

We will also present our triple-axis fiber optic gyroscopes which offer low noise performance in ultra-compact and lightweight units with low power consumption of 2 Watts.

The G181 is a cylinder-shaped unit measuring ∅46x111mm and weighing 160 gr. 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 125 gr. These industry-leading SWaP parameters are combined with low noise performance of 0.025°/√h ARW and a bias stability of 1°/h. 

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

The FOG IMU U121D is housed in a compact Al case (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. Another FOG IMU with a cylindrical form-factor is the U183(M). It is 46mm in diameter and weighs 200 gr. The unit consumes as low as 2 Watts, and features 0.03 °/√h ARW, 1°/h bias stability.

Our inertial sensors are designed to suit various space- and layout-limited applications including inertial navigation systems (INSs) in UAVs / UUVs / USVs / ROVs.
