1. Main Product Features
A. High precision: Compared with MEMS gyroscope, FOG has lower
offset drift and higher angular velocity resolution, which is
suitable for high-precision navigation system.
B. Three-axis integration: no need to combine multiple gyros,
reducing volume and weight, improving system integration and
reliability.
C. No mechanical moving parts: Compared to mechanical gyroscopes,
FOG is frictionless and wear-free, resulting in longer life and
higher reliability.
D. Resistant to vibration and shock: Suitable for highly dynamic
environments such as drones, missiles, and flying machines.
Ready-to-use, no warm-up required: Compared to laser gyroscopes
(RLG), FOG has a short start-up time and fast response.
E. Low-power design: Optimized energy consumption for
battery-powered systems such as UAVs and portable navigation
devices.
