Sigma and Argonyx INS units by Safran

For over 70 years, Safran Electronics & Defense has been an acknowledged leader in inertial technologies — mechanical, laser, fibre-optic and resonant — and a European leader in inertial navigation systems for land, maritime, naval and aerospace applications.

Safran markets a huge range of INS products for naval applications. The Sigma 40 family, long considered the gold standard in key areas, includes INS units based on either the ring laser gyro (RLG) technology or the HRG Crystal hemispherical resonator gyro technology. It is now joined by the Argonyx range.
