Parameters
Comments
• When baseline parameters are output in time-tagged
mode ($PASHS,VEC,TT), the ATT message is generated
only for those epochs for which reference data are
available. In fast mode ($PASHS,VEC,FST), the ATT
message will be generated for each receiver epoch using
additional extrapolation algorithms.
• d7=0 does not necessarily mean that the corresponding
position message (e.g. POS) includes a “fixed” RTK
position solution. When d7>0, the reported attitude is not
necessarily wrong. This is because even a float solution
