Modern pressure sensors can be used to improve localization accuracy in local positioning systems. A mobile object altitude estimation can be obtained by processing the pressure sensor data. High accuracy of the estimation can be only achieved by processing a number of consecutive measurements due to their stochastic nature. The present paper provides an algorithm for calculating mobile object altitude estimation as a mean value of a number of measurements from the fixed nodes with known altitudes. The estimated variance and bounds are revealed for different number of the conducted measurements. It is shown that processing more samples from one sensor gives larger contribution to accuracy than using data from more distributed sensors. The algorithm of choosing the optimal set of sensors for altitude estimation is proposed in the last part of the paper. Some useful recommendations on how to use the derivations in practice are also described.
