摘要：
The invention relates to a method of correcting the effects of aging of a measurement sensor upon turning on the sensor. It also relates to a device delivering measurements corrected for the effects of aging of the device. According to the invention, the method of correcting the effects of aging of a sensor starts by on turning on the processing unit. The absolute time information is transmitted from a satellite positioning receiver to a processing unit. The age of the sensor is determined by comparison of the date of manufacture of the sensor and the absolute time information. Corrections to be made to a sensor measurement, based on the age of the sensor and on the degradation law, are determined. The corrections are applied to the sensor measurement.
