ANS-310K Tactical Land Inertial Navigation System

ANS-310K is an integrated position and attitude determination system for land vehicles. ANS-310K provides linear acceleration, linear and angular velocity, position, attitude to the host vehicle systems continuously. ANS-310K consists of strapdown inertial measurement unit, system processor unit, power supply unit, Embedded GPS Receiver (EGR) and chassis. ANS-310K is capable of using 12 channel commercial SPS GPS receiver as embedded GPS receiver. ANS-310K is also capable of using external GPS receiver.

The tightly coupled, embedded INS/GPS and integrated odometer mechanization of ANS-310K provides improved performance for land platforms.

ANS-310K provides hybrid (inertial+ GPS + Odometer) navigation solution and GPS only navigation solution simultaneously. ANS-310K has the capability of providing high performance position and attitude with odometer update in case of lack of GPS signals.

ANS-310K is a cost effective solution for all types of ground-based vehicles requiring position and pointing during their mission.

ANS-310K is an open architecture and hardware/ software flexible unit which can be adapted to various land platforms.

Long mean time between failure (MTBF) and internal built in test capability reduces the logistics requirement to a minimum. ANS-310K does not require periodic maintenance.
