I\’m new to this, thanks for your patience.
It\’s my understanding that correction affects accuracy, but not necessarily precision. If that\’s correct, how fast does precision drift over time. For example, I want to create a topo map of a small field (15 acres), absolute values aren\’t necessary, I only care about the relative topography. Is there a time window in which I can expect uncorrect gps readings to have precision in the sub 3cm range? If so, is that window measured in minutes, hours, days? I have the simpleRTK2B – Basic Starter Kit.
