Testing and evaluation of a differential gnss tracking device for alpine- and cross-country skiing

Paper i proceeding, 2019

This paper is assessing the need to find a tracking technology that can be applied in an alpine location, tracing cross country skiers as well as downhill skiers. The technology used is the differential Global Navigation Satellite System (DGNSS), a high accuracy positioning technology. The basic GNSS uses several satellite navigation systems, always providing good position coverage. The differential part adds more accuracy by using a precisely surveyed reference station. Thereby the tracked object is given a correction signals obtaining a higher accuracy on positioning data. The technology demonstrates the capability deliver accurate data, but there is a need explore the use for continuous tracking of an athlete.
