Timestamping for an array of low-cost sensors

Authors: E. Dorveaux, D. Vissiere, A.P. Martin, N. Petit IFAC workshop on programmable devices and embedded systems 2009
This paper describes a technique for timestamping data from an array of sensors. This is a challenging issue that needs to be solved for the magnetometry-based navigation system presented here. This system uses finite difference schemes to evaluate spatial and time derivatives of a vector field. The accuracy of the timestamping method is critical. In the context of this particular application, we detail the various difficulties that must be circumvented. We present a software architecture, which was run on an experimental device.
