Trimble PP Kinematic
I have processed (a lot) of airborne GPS data, but have not done any PP Kinematic on the ground in the data collector.
I recently had a client send me some data that was collected in PPK mode. It was stop and go, they were occupying photo control as observed control. Worked well. So I looked into it and saw that on the data collector it wants a certain amount of time to initialize, the defaults basically same as fast static (8 minutes for 6 or more SV’s).
But, if doing a real time kinematic survey the initialization time is typically a few seconds. So I wonder what is the difference? If both the rover and the base are collecting at 1s epochs, why does it take so long to assure a successful init? I realize that in real time the receiver is continuously tracking the signal, and storing a reading every epoch, but if there are no cycle slips why can’t the post processed data init as quickly?
I would be interested to hear from anyone who does this style regularly to see what the real init times are.
