Evaluation around test track
We took an early prototype for a comparison test at a 400 m test track: we ran 4 laps with 3 different units:
The test track used is located in an area with many surrounding building and the weather was pretty cloudy so the test was particularly demanding for any GPS device. In subsequent test, during touch games played in good weather and on pitches less surrounded by buildings, it must be said that the commercial unit was providing a much better signal.
Another analysis of the data can be done by analysing in detail the data contained for one lap of each one of the device using the great free software “MapSphere GPS Track Editor”. You see the result in the graph below in which colour is proportional to the speed measured and arrows are used to connect each data sample. The brief analysis is:
Results of an additional tests will be posted here by the end of January.
