The VG221 fiber optic gyroscope (FOG) stands out as the most compact and lightweight gyro on the market.
With dimensions of ∅33 x 12mm and a weight of 15 grams, the VG221 sets a new benchmark for SWaP (size, weight, and power) parameters within the industry. These industry-leading physical parameters of the VG221 are coupled with a remarkable performance with 0.05 °/√h ARW and 1 °/h bias stability. Operating at a power consumption of just 0.3W, this FOG sensorensures minimal energy usage.
The VG221 series includes variants, encased in μ-metal for enhanced immunity to magnetic fields(0.1°/h/Gauss), and the VG221LN model, with even lower level of ARW at 0.025 °/√h. All variants in the series are ITAR-free.
The world's smallest FOG is an ideal solution for a diverse array of applications, including miniature gimbal stabilization, drone navigation, borehole surveying, underground utilities mapping, and more.
