Greetings to the community.
The question is simple. Is there a website where raw data from a kinematic (stop-and-go) survey can be post-processed?

You can download a program for free called 'Emlid Studio' that will work. Assumption being you have some good base or CORS data to work with.

Just because I'm paranoid, doesn't mean they aren't out to get me.

Yes, I'm familiar with that program. The problem is that for stop-and-go post-processing, the software requires you to attach the .csv file generated by the data collection program (EMLID Flow). If you don't perform the survey with an EMLID receiver, you can't perform post-processing with that program.

I don't know about a website or free, but this software might be the tool for you. I have used it for processing static and it's pretty robust.

I think the GAPS (GNSS Analysis and Positioning Software) tool by University of New Brunswick is what you are looking for.

I know one person who was involved in the development of GAPS, other than that I know nothing more.

Guys, I thank you all for your interest in the topic. This last point is exactly what I was looking for. I hope it helps others as well.

I'm not sure that is entirely true but now you have me curious because I'm getting ready to use this for correcting drone PPK data I'm collecting my base data with iG9 base/rover receiver and a drone. If you collect your data in Rinex format, it should work? For reference see this video.

(PPK rover corrections at minute 11:20)

Here is an AI overview to the question 'can you do PPK corrections using Emlid Studio without using Emlid Flow'

Yes, you can perform PPK (Post-Processing Kinematics) corrections using Emlid Studio without needing Emlid Flow, by importing raw data logs from both the base and rover receivers.

Here's a breakdown of the process:

Data Collection:

You'll need raw data logs (RINEX files) from both your base and rover receivers.

Emlid Studio Import:

Open Emlid Studio and import the raw data logs from both the base and rover receivers.

Processing:

Emlid Studio will then use these raw data logs to perform PPK processing, allowing you to obtain precise coordinates for your survey data.

No Emlid Flow Required:

While Emlid Flow is used for data collection and real-time RTK corrections, it's not necessary for the PPK processing stage in Emlid Studio.

Stop & Go Workflow:

If you are using the Stop & Go workflow with Emlid Flow, you can export a CSV file from Emlid Flow and import it into Emlid Studio for PPK processing.

Geographic Coordinates:

Emlid Studio will output the results in geographic coordinates (latitude, longitude, and height).

Transforming to Projected Coordinates:

To obtain projected coordinates (e.g., UTM), you will need to use Emlid Flow or a third-party software to transform the coordinates.

NTRIP-capable devices.

Yes, for drone kinematics, post-processing can be performed by simply uploading the converted file to rinex. However, for on-foot kinematic surveys (stop and go), it is necessary to upload the .csv file generated by Emlid Flow to the program so that the program can perform the adjustment and generate a point-by-point report (for example, for each vertex of a surveyed polygon).
