Tactical North Seeker

NS-40

NS40 is an ultra small Inertial based tactical North Seeker and keeper, designed to work in harsh conditions. With stand alone capabilities or as an add-on to any navigation system, NS40 is the best cost effective North seeking device on the market.

True North in GNSS deprived environment

Based on open loop FOG technology, NS40 can detect earth rotation and calculate the geographic north (True North)

Fast and accurate

Initial North azimuth calculated after less than 60 seconds with full accuracy after 300 seconds. Integrated IMU for full 6 DOF measurements.

Cost to performance 

A small tactical system, NS40 is a cost effective solution for any navigation system that must have an accurate initial North azimuth
