Correct Data on my GPS tracker software

Hello, I was involved in a similar project a year ago. We had to draw the path of the vehicle using gps tracking data. Our problem was that the data was sometimes corrupted, but that was connection problems. In the end we implemented hard algorithms to smooth data input. Maybe I can help you with your project? What software do you use? Can you explain a little bit more about the problem? Contact me, if you need help.
