Description
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!
Thanks!

- 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.
