    • The invention relates to a method and a system for determining a target variable to be measured in a mobile device. A first physical variable is measured with the aid of a first sensor and a second physical variable with the aid of a second sensor. The second physical variable is different to the first physical variable, or is measured using a different technique. The value of the target variable is calculated with the aid of the measurement of the first and second physical variables. An estimate for the target variable is determined with the aid of at least the measurement of the first physical variable. At least a first error estimate is determined, which depicts the accuracy of the measurement of the first physical variable. The estimate of the target variable is filtered using both the first error estimate and the measurement of the second physical variable.

    • The invention relates to a portable electronic device and method for determining altitude. The device can comprise a satellite-positioning sensor for determining the elevation of the device on the basis of satellite data, a barometric sensor for measuring atmospheric-pressure information and/or an acceleration sensor for measuring acceleration information, and means for determining the altitude reading on the basis of the satellite-based elevation and the atmospheric-pressure and/or acceleration information. According to the invention, the means for determining the altitude reading are arranged to calculate a corrected altitude reading with the aid of the rate of change in elevation determined at least partly on the basis of the elevation determined on a satellite basis and atmospheric-pressure and/or acceleration information. With the aid of the invention, the altitude profile of exercise can be measured precisely.
