Hennepin, IL | Again I know enough to be dangerous. The way I understand it is the datum has nothing to do with the satellites themselves. It's essentially just a model of the earth's surface/shape which is loaded into the receiver (rover and base both). Since the earth isn't a perfect sphere, this model is required to approximate the center of the earth, from there it can figure its position on the surface. There are multiple datum used and a lot of receivers can switch between different ones. Its my understanding that WGS84 is probably the most common and it won't be affected, only NAD83 is being changed. So.eone who isn't AI generated can feel free to weight in on whether I'm close or not. | |
