RTK is real time correction data. PPK is not.
With PPK you dont need live data link between rover and base, you just need log from rover and base and process it later
Well, yes. But the challange is to know where that point is in postprocess, thats why if i do postwork, i use a bit more time over eachpoint just to seperate it better in the log, like my comment her
With RTK you can use survey mode and get the coordinates in an instant
