ANS-530K Land Inertial Navigation System

ANS-530K is an integrated position and attitude determination system for land vehicles specifically for high-shock artillery gun systems. ANS-530K supplies linear acceleration, linear and angular velocity, position, attitude to the host vehicle systems continuously.

ANS-530K has an open architecture and hardware/software flexible unit which can be adapted to various land platforms.

ANS-530K consists of strap down inertial measurement unit, system processor unit, power supply unit, Embedded GPS Receiver (EGR) and chassis. It is capable of using 12 channel P(Y) coded SAASM GPS receiver as embedded GPS receiver. ANS-530K is also capable of using external GPS receiver.

The tightly coupled, embedded INS/GPS and integrated odometer capability of ANS-530K provides improved performance for land platforms.

ANS-530K provides both a hybrid (inertial + GPS + Odometer) navigation solution and also inertial only navigation solution or a GPS only navigation solution simultaneously. It has the capability of providing high performance position and attitude with odometer update in case of lack of GPS signal.

Long mean time between failure (MTBF) and internal built in test capability reduces the maintenance requirement to a minimum level.
