Accuracy estimates with Trimble R1 seem to be off

[jeb62868]

I'm experimenting with your cordova-plugin-bluetooth-geolocation using a Trimble R1 and the accuracy estimate seems to be off. The Trimble GNSS Status app is reporting SBAS corrected accuracy of less than 50cm and 8 decimal positions in the lat/lon values. What I'm getting through the Bluetooth NMEA stream seems to "stick" at an accuracy estimate of 2.0m and doesn't go lower and is only showing me six decimal positions in the lat/lon (which is correct if the accuracy is 2m).

Looking in your code I am curious about this:

'accuracy': gps.state.hdop && gps.state.hdop * 4

Is there any way to get the same coordinates and level of accuracy through the NMEA stream as I'm seeing in the GNSS Status application?

It seems that GST should be used to calculate accuracy correctly.
