I did some tests over the weekend with “PPK” and “Stop and Go”.
I need to know if I understand correctly each method:
The PPK will record points per second of time as configured (1Hz, 5Hz or 10Hz), correct?
Each PPK record will be processed in Emlid Studio and a vector is created, correct?
Is it like an RTK, with a single observation, but post-processed?
What about Stop and Go?
It also records as per recording time while walking.
In Emlid Studio, the CSV of the RTK is linked and the occupancy points are identified, correct?
In this case, processing is carried out and numerous observations regarding the point are considered and then an average is made, correct?
How is this average made?
Which observations go into calculating the mean? Is there any parameter that “chooses” which observations to average? For example a scattering radius?
Is it like averaging all recorded observations within a tolerance radius?
Is CSV only used to get the antenna height? Or does it influence something else in the processing?
The only difference between Stop and Go and Fast Static is whether or not to keep GNSS writing logs?
You’ve pretty much summed up Kinematic processing: you get single observation points collected at regular intervals. The accurate coordinates are calculated during post-processing.
As for Stop&Go, you’re right that it averages the solutions. But the solutions used by Emlid Studio depend not on the radius but on the point’s time span from a CSV file. Tapping the Data quality check marks, you can also choose which solutions are included.
I’d say Stop&Go is a semi-kinematic technique because you can collect several points one by one. As you noticed, the receiver still records data when you move from one point to another. This part will just be omitted in the calculations.
So if I record a point in RV3, that record will be used to define a time lapse to identify the static point.
What is this time?
If I stay on point for 5 minutes, or if I stay on point for 60 minutes, will there be differences?
And does the point solution in RV3 influence this determination?
Does it make a difference if I collect Fixed, Floating or Autonomous point for this determination of the time interval that will be used to determine static observations of that point?
