ANS-510K Land Inertial Navigation System

​ANS-510K is an integrated position and attitude determination system for land vehicles. ANS-510K supplies linear acceleration, linear and angular velocity, position, attitude to the host vehicle systems continuously. ANS-510K has an open architecture and hardware/ software flexible unit which can be adapted to various land platforms.

ANS-510K consists of strapdown inertial measurement unit, system processor unit, power supply unit, Embedded GPS Receiver (EGR) and chassis. ANS-510K is capable of using 12 channel P(Y) coded SAASM GPS receiver or commercial SPS GPS receiver as embedded GPS receiver. ANS-510K is also capable of using external GPS receiver. The tightly coupled, embedded INS/GPS and integrated odometer mechanization of ANS-510K provides improved performance for land platforms.

ANS-510K provides a hybrid (inertial+GPS+Odometer) navigation solution, inertial only navigation solution and a GPS only navigation solution simultaneously. ANS-510K 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 logistics requirement to a minimum. ANS-510K does not require periodic maintenance.
