DEVICE AND METHOD FOR CORRECTING AGING EFFECTS OF A MEASUREMENT SENSOR

摘要

The invention concerns a method for correcting aging effects of a measurement sensor, when the sensor is switched on. The invention also concerns a device delivering measurements after the aging effects of the device have been corrected. The invention is characterized in that the method for correcting aging effects of a sensor includes, when the processing unit is switched on, the following steps: transmitting information in absolute time from a satellite positioning receiver to a processing unit; determining the age of the sensor by comparing a manufacturing date of the sensor and absolute time information; determining corrections to be made to a measurement of the sensor based on the age of the sensor and the degradation law; applying the corrections on the measurement of the sensor.
