Hi,
Although J-Field become so advanced regarding the statistical methods that provide confidence and consistency, in some canopy isolate points, we need more than 2 steps + validate rover algorithm.
The base can also play an important role by taking the final decision in this process.
So, in practice, only for some difficult points, we usually invert the base and rover. We keep the rover in a stable position with a tripod clamp and apply a base profile. Then apply a rover profile to the base. Finally we can compare the vector and coordinate to the main base like in a classical two way traverse.
For us this is the final step before validating a RTK position using one of the advantages of Javad receivers to be rover or base.
We know that the base should not be use in bad places, but for some isolated locations this procedure give more confidence. Note that in dense canopy, the inclusion of BEIDOU observations into RTK can improve the position availability by up to 30%. After inversion, the original base-rover profile can be restored.
Very useful could be an additional display system at the rover using RAMS, to remote control the base (usually android phone/tablet). Otherwise we need a second person to change the base profile. This way of working is more suitable in areas with good coverage of GSM carriers and with TCP IP corrections.
Regards.
