For many thermal processes described by partial differential equations, parametric identification of the model can be performed by solving an inverse problem. Measurements noises occurring on one or several measured characteristic states have to be carefully taken into account in order to provide robust identification procedures. However, spatial inaccuracy of the sensor location is rarely investigated. In this paper, a thermal process is presented in order to study the effect of this class of measurement noises on identification robustness. Then the problem of optimal location of the sensor is stated.
