3.5.1 PDP and GLIDE
Pseudorange/Delta-Phase (PDP) and GLIDE position filters can be used for single-frequency single
point, WAAS or DGPS positioning. Refer to the
Family Firmware Reference Manual
To reset the PDP or GLIDE filter:
pdpfilter reset
To enable the PDP filter:

Steadyline

®
The Steadyline functionality helps mitigate the discontinuities that often occur when a GNSS 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 NovAtel CORRECT PPP, DGPS,
WAAS+GLIDE or even autonomous GLIDE (see Figure 16, Positioning Change Without Steadyline).
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.
