3.5.2 PDP and GLIDE Configurations

Pseudorange/Delta-Phase (PDP) and GLIDE position filters can be used for single-frequency
single point, WAAS or DGNSS positioning. Refer to the PDPFILTER command and PDPMODE
command in the
To reset the PDP or GLIDE filter:
pdpfilter reset
To enable the PDP filter:
pdpfilter enable
Ensure the PDPFILTER command is used before the PDPMODE command. Set the PDP type
and kinematic type according to the application. For most kinematic applications:
pdpmode relative dynamic or pdpmode relative auto
The rest of the setup is position type and log dependent according to the application. For
example, details of the PSRDIFFSOURCE, INTERFACEMODE, SERIALCONFIG and other con-
figuration commands are outlined in the
Also refer to the NovAtel application note

3.6 STEADYLINE

The STEADYLINE
receiver changes positioning modes. The effect is especially evident when a receiver transitions
from an RTK position mode solution to a lower accuracy "fall back" solution, such as DGPS,
WAAS+GLIDE or even autonomous GLIDE (see Figure 10: Positioning Change Without
STEADYLINE below). Smooth transitions are particularly important for agricultural steering
applications where sudden jumps are problematic.
The STEADYLINE feature internally monitors the position offsets between all the positioning
modes present in the receiver. When the current positioning mode becomes unavailable, the
receiver transitions to the next most accurate positioning mode.
The setting in the STEADYLINE command determines how the receiver transitions to the next
positioning mode. The following sections describe the STEADYLINE modes.
