2 Operation Details
• The
command can be used to filter out measurements from un-
healthy satellites: these measurements will not be used by the PVT algorithm, nor will
they be included in the
SBF block.
• To further reduce the code measurement noise, the receiver can be ordered to smooth
the pseudorange by the carrier phase. This technique, sometimes referred to as a
"Hatch filtering", allows to reduce the pseudorange noise and multipath. It is controlled
by the
command and is disabled by default.
• The
command can be used to enable or disable the mit-
igation of multipath errors on the pseudorange and carrier phase measurements. It is
enabled by default.
For advanced applications or in-depth signal analysis, the
SBF block contains
various additional data complementing the
SBF block. Among other things, this
block reports the multipath correction applied to the pseudorange (allowing one to recom-
pute the original pseudorange), and the observable variances.
2.2.1
Pilot vs. Data Component
Most modern GNSS signals consist of two components: a so-called pilot component and a
data component. For such signals, the measurements are based on the pilot component for
optimal performance. In particular, the reported C/N
o
value is that of the pilot component
only.
For all signals having a pilot and a data component, the table below indicates which com-
ponent is tracked by Septentrio receivers. Note that your particular receiver model may not
support all of these signals.
