I am new to surveying with gps. Can I measure a point using only one Trimble R8 m3 receiver and a tsc3 data collector. I need the point to be survey grade, with in a foot. Can it be done with just one receiver? What would you recommend to post process, (OPUS, Trimble RTX) I am doing this in Belize. If it can be done, what is the correct way to do this?
