Description

Problem:
Recording with external GNSS receiver records points on a different place than the crosshair is. With internal GPS the recording works fine.

To reproduce:

  1. Connect app to an external GNSS receiver
  2. Start position tracking
  3. Check where edges are being created
  4. Stop tracking
  5. The line has some offset from your actual position.

Research direction

Reproduce the issue with an external GNSS receiver using the five steps in the report, then compare the tracked line with the crosshair and with internal GPS tracking. Trace how the external position is used for edge creation; done means recorded edges align with the actual position and no longer show the reported offset.
