Inclinometer Based North Finder is a new concept that allows reaching direction information from inclination. It uses specially defined "Yalcin Curve" which is unique for each latitude of the measurement point on the Earth. The "Yalcin Curve" is simply a measure of the amount of deformation of gravity acceleration caused by centripetal acceleration in the measurement point.The North finder can be implemented using inclinometers placed on a plane in a predefined order. The device is also equipped with a high speed microprocessor unit which calculates the "Yalcin Curve" values depending on the Latitude of the measurement point and compares them with the measured "Yalcin Curve" values obtained from the outputs of the inclinometers used. Inclinometer Based Direction Finder has many advantages over today's other North Finding Gyros. It provides higher accuracy and real time output in a lower cost and lighter package.
