VN-200 SMD

VN-200 SMD

The VN-200 SMD (Surface-Mount Device) is a miniature high-performance GPS-Aided Inertial Navigation System that combines MEMS inertial sensors, a high-sensitivity GPS receiver, and advanced Kalman filtering algorithms to provide optimal estimates of position, velocity, and orientation for industrial applications.


GPS / INS Kalman Filter

The VN-200 incorporates the latest advancements in Aerospace grade Kalman filter inertial navigation algorithms specifically tailored to solve problems typically faced by industrial users.

Industrial control applications require high accuracy low latency position, velocity, and attitude measurements. GPS provides long-term position accuracy, but is incapable of providing low-latency high bandwidth measurements. Inertial sensors provide high bandwidth acceleration and angular rates, but cannot provide long-term position and orientation accuracy due to drift and integration errors. Utilizing an onboard Extended Kalman Filter the VN-200 is capable of combining in an optimal manner the high bandwidth inertial measurements with the high accuracy low bandwidth GPS measurements. The VN-200 provides industrial users with access to a continuous stream of low latency high accuracy position velocity and attitude measurements at a rate of up to 200Hz.

10-Axis MEMS IMU

Utilizing the latest advancements in MEMS technology, the VN-200 incorporates a wide assortment of inertial sensors including a 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer, and a barometric pressure sensor. The VN-200 has been carefully designed to provide the highest performance achievable, by eliminating common error sources such as sensitivity to supply voltage variations and temperature dependent hysteresis. To provide the highest level of accuracy, each VN-200 is individually tested and characterized over the full operating temperature range to determine the bias, sensitivity and cross-axis alignment for each individual sensor. Calibration coefficients are stored on the sensor and are fully temperature compensated in real-time onboard to ensure high accuracy measurements over the full operating temperature range.
