Points duplicated in the Emlid Flow Job

  1. Emlid Flow app version 9.12
  2. The name and parameters of the coordinate system : EPSG 7801 (BGS2005/CCS2005)
  3. Detailed issue description: During survey of topo points ( single RTK measurements) suddenly the app starts to duplicate the measurements. For example: Job with 150 measurements have 280 points. Points 1-20 are OK. Points 21-150 are duplicated (21, 21, 22, 22, 23, 23, …etc.)

What can be the reason?
The issue is found in Emlid Flow on Android with RS2.

I got the error of duplication of the point in the survey that I made on 02/17/2024, from point 45 to the last 61; the previous ones from 1 to 45 were taken without duplicate. Days later I have done other work and the points have not been duplicated.
Emlid RS2 with version 31.8 and Emlid Flow 9.12

Hi guys,

We’re investigating this behavior with our development team. Could you please provide us with the following information? Your answers would be of great help in our investigation.

  • Did you connect to Reach via Wi-Fi or Bluetooth?

  • What type of Correction Input do you use?

  • Are the FIX-only and Averaging timer options enabled in the Survey settings tab? I’ve attached the screenshot of where to find the Survey settings tab.

  • What coordinate system do you use for your project?

  • Did you notice something specific before the duplication occurred? For example, a change in the solution status.

  • Do you see the same points duplicated also in the Objects list in Emlid Flow?

*I connect via Wi-Fi.
*I use Real Time Positioning Service (SPTR) from IGN Spain with a mounting point in network corrections, VRS3M or CERCANA3M solution, RTCM3.2 (MSM) format.
I am in Tenerife and I use REGCAN95/UTM zone 28N Tenerife Height
*FIX only
*I didn’t notice anything. When I got to the download in the office is when I detected it.
*If they look the same.

The same with me:
*I connect via Wi-Fi.
*I use NTRIP corrections.
*EPSG:7801 BGS2005/CCS2005
*FIX only
*I didn’t notice anything. When I got to the download in the office is when I detected it.
*I see the same points duplicated in the objects list in Emlid Flow.

Thank you for sharing all these details! I’ve passed them on to our developers, and they’re already investigating it.
