[Qgis-user] GPS issue on android tablet

[Richard McDonnell]

This is down to the accuracy of the Receiver, nothing to do with QGIS.
You wont get Survey Grade data collection from any Tablet on the market 
at present. Even with a Survey Grade GNSS Receiver connected to your 
tablet, a 3.0 meter accuracy would be best case scenario.  Your only 
solution is a dedicated GNSS Enable hand-held data collection unit, 
utilising a real-time correction service, a number of Providers provide 
such solutions, but they are expensive.
Regards,

Richard.
