Number:
4028
"OnChange"
interval: default PVT output rate (see 4.1.8)
The
block contains the relative position and orientation of one or more
base stations, as seen from the rover (i.e. this receiver). The relative position is expressed in
the East-North-Up directions.
For highest accuracy, the receiver tries to compute the baseline from rover antenna
reference point (ARP) to base ARP. See the description of the
BaseVectorCart
block for
details.
Accurate ARP-to-ARP baseline is guaranteed only if both bits 0 and 1 of the
Misc
field
are set. Otherwise, centimeter-level offsets may arise because the receiver cannot make the
distinction between phase center and ARP positions. See section 2.5 for a discussion on the
phase center and ARP positions.
The block supports multi-base operation. It contains as many sub-blocks as available
base stations, each sub-block containing the baseline coordinates relative to a single base
station identified by the
ReferenceID
field.
