<![CDATA[GPS Values From INS app appear quantized]]>I recently set up an INS system using the openIMU300za and upon initial testing noticed the GPS values appear quantized to fixed ~1.5 meter increments.
Is this an expected result of an algorithm running on the unit and something I can turn off?

pld->pos[i] = dData[i];
This will be fixed in next release
Also binary image with this fix will be published on aceinna developers website.
