FOG North Finder vs. FOG INS: What’s the Real Difference?

A FOG north finder and a FOG INS are not the same. A north finder provides true heading using Earth’s rotation, while a FOG INS delivers full navigation data—position, velocity, and attitude—through gyroscopes, accelerometers, and navigation algorithms.

10 Common Mistakes Engineers Make When Using Fiber Optic Gyroscopes (FOGs)

FOGs often fail in the field not due to poor design, but because of usage errors—misalignment, vibration, weak calibration, or ignoring EMI. Avoiding these 10 common mistakes ensures navigation-grade performance. GuideNav provides ITAR-free FOGs with expert integration support to help buyers and engineers succeed.

Open-Loop or Closed-Loop FOG? Understanding the Difference

Open-loop FOGs are compact and cost-effective, with medium accuracy (1–10 °/h) for UAVs and robots. Closed-loop FOGs deliver ultra-high precision (0.001–0.1 °/h), making them essential in submarines, missiles, and aerospace systems.
