Summary:A method for estimation of relative coordinates between at least two parts of a system generally comprises two main steps of: measuring a set of relevant coordinates for each part of the system; and processing each measurement result to estimate the relative coordinates between at least two parts of the system. The system includes a main body and at least one sub assembly. A first sensor A is configure to measure the movement rate of at the sub assembly; a second sensor B is configure to measure the movement rate of the main body; and a third sensor C is configured to estimate the integrator offset and the drift rate due to the first sensor A bias and due to the second sensor B bias.
