High Precision Kinematic GPS Positioning Of Ski Jumpers

Thomas Blumenbach

Abstract:	High precision carrier phase based GPS positioning requires a reliable integer ambiguity fixing. Problems arise if the measured time span is very short and additional signal shadowing results in a poor geometrical satellite distribution. Exactly this situation exists if someone try’s to measure the trajectory of ski jumpers with GPS. Most of the jumping hills are north orientated within deep valleys and not very suited for GPS applications. This paper describes a successfully hardware based approach to solve the ambiguity fixing problem. The correctness and reliability of integer ambiguity fixing could be increased using only one measured epoch. The system was successfully tested during summer and winter training on the K95 jumping hill “Fichtelbergschanze” in Oberwiesenthal, Germany.
