Hi all, We use a lot of GPS derived positions and would like to increase the accuracy of these. We currently use a survey grade GPS but this gives us approx 1m repeatability and maybe 0.4m accuracy over a short time. We would like to get down to a few cm's accuracy. I believe there are 2 ways of doing this:
1. RTK GPS - 1 to 2 cm accuracy and repeatability BUT problems with cost and base stations. 2. Post processing - record the raw GPS info and use software to post process the raw GPS info to give accuracies in the 5 to 10cm ranges. E.g. HYPERLINK "http://www.waypnt.com"http://www.waypnt.com and many others. So the question is: Does anyone use post processing software with MapInfo - would they recommend it?
