The invention relates to a method and apparatus pertinent to improving the accuracy of weighing measurements. Specifically, the invention relates to a method and apparatus for improving the accuracy of weighing measurements by making use of geometric information. A weighing result is affected by the acceleration of earth gravity, which varies according to location and altitude. According to the Applicant's judgement, the best preferred embodiment of the invention comprises measuring geometric information directly by means of a cellular network (210) without satellite receivers and utilizing the same in the determination of a weighing system's location and thereby in the calibration of an acceleration of free fall (230, 240). The inventive methods and equipment enable a geometric information based precise calibration of weighing results, even when satellite positioning proves impossible, inconvenient or expensive. |
