GPS Information / Position always shows "-1.0m" for accuracy

Category:GPS Live Tracking
Affected QGIS version:3.6.2 Regression?:No

I tried several versions of QGIS (2.18, 3.6, 3.4)

All of them show the same behaviour:

The H Accuracy and V Accuracy is always "-1.0m".

If you use a receiver in RTK-Mode, you really want to see the residuals..

Vertical RMS

VRMS = math.sqrt(math.pow(GST_Field_8, 2))

Horizontal RMS

HRMS = math.sqrt((math.pow(GST_Field_6, 2) + math.pow(GST_Field_7, 2))/2)

Positional RMS

PRMS = math.sqrt((math.pow(GST_Field_6, 2) + math.pow(GST_Field_7, 2) + math.pow(GST_Field_8, 2))/3)

Please make that available!

  • Priority changed from High to Normal
  • Status changed from Open to Feedback
  • Description updated (diff)
  • Subject changed from GPS Information / Position allways shows "-1.0m" for accuracy to GPS Information / Position always shows "-1.0m" for accuracy

What's the problem with this? -1.0m is just the initial value, apparently means "unknown accuracy" and is only used for informational purposes.
