We are working with a base station and with moving base/rover configuration.
In some areas the accuracy provided by the GPS is around 5cm but with float mode. In this mode, the postion suffers from some jumps and the gps data in not valid for localization purposes.
We would like to know if it is possible to get that accuracy in float mode and what are the generic causes of this float mode. In https://www.ardusimple.com/question/3d-dgnss-float-fixed-what-meaning-exactly/ there are some relations between the accuracy and fixed and float mode.
Thanks in advance,

Sure, it means it can’t close the deal on 2 cm because there is too much measurement noise, things like indirect signals reflecting off close surfaces, or being blocked on one side, like in the shadow of a house or fence. A less than ideal base station sky view will also diminish the ability of the rover to resolve its position.
Use ground planes under the antennas, use the uCenter SkyMap to see what blind spots you have, mount the antenna so it doesn’t oscillate/vibrate, and do a proper survey of its location so the measurements/observations aren’t distorted
