Dear colleagues,

we are looking for a method to smooth GPS data. We measured speed and
distance of young soccer players with a gps device collecting data at 1
Hz. Because we want to seperate and analyse different parts of the
match, we calculate distance and speed from the latitude and longitude
trackpoints manually. Finally, we have to eliminate/reduce the impact of
outliers. Averaging three values of the calculated speed and distance
seems to work fine (at least it is very similar to the values given in
the software of the manufacturer), but maybe you could provide methods
superior to averging three values?

Best regards,
Mirko Brandes
