GNSS systems are widely used in many sports. Lastly observed increase of popularity of this kind of monitoring is observed by new equipment appearing on the market. Our aim in this study was to assess validity and reliability of TITAN2 GNSS equipment. Two protocols were used: protocol one consisted of 9 laps of 400(m) long athletes track where the devices were carried on an electric car with constant velocity, protocol two was using gold standard proposed by Coutts & Duffield (2010) consisting 128,5m track of different move patterns including 20m sprint with photocells which was covered by 19 male adult professional football players. Results: total distance (TD) CV% was ranging from 0.32 to 0.55%, TD at maximum speed CV% was ranging from 0.45% to 0.78%, maximum speed CV% was 0.206% to 0.609%, TD on 128.5(m) track had CV% of 1.4%. These results prove that TITAN2 GNSS is a reliable device providing valid data to the users.
