Set Command Library
• When raw data reduction is effective, any antenna name
messages generated by the receiver will include the name
of the virtual antenna, and not the antenna serial number
or the setup ID.
• If no reference position has been entered in the receiver,
raw data reduction is performed in such a way that the
location of the L1 phase center is left unchanged.
• Antenna reduction is performed in such a way that the
ARP is unchanged.If the reference position is given with
respect to the ARP, and not to the L1 phase center, then
the receiver computes the position of the ARP using the
physical parameters of the antenna, and then re-computes
the position of the L1 phase center according to the
ANP,OUT antenna parameters. This guarantees that the
reported reference position, the antenna name and the
observables are all consistent with one another.
