While surfing the net, I came across this chip I thought it is worth writing about it.

The VN-200 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.

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.
