Positioning Application: Is it possible to enable the velocity profiles on the 4500 / 6560 / 5060 single channel utility?
PosApp (SimGEN / SimREPLAYplus / SimREPLAY)
Using the Single Channel Utility available from PosApp menu [Tools-->4500/6560/5060/4150 Utilities]
Using one of the following simulators
No - this is not possible
But you can create the same velocity profile effects using PosApp's Pseudorange Ramp feature.
Refer to article
to learn about PR Ramps
Refer to the GSS4100 user manual,
, for a summary of the velocity profiles
explains that SimCHAN is the basis for this Single Channel Utility
The velocity profiles were a feature available for use with the GSS4100, not the STR4500 / GSS6560 / GSS5060.
The GUI therefore shows the feature greyed out when SimCHAN was modified for use as the Single Channel Utility with these simulator models.
For that reason you cannot re-enable it.
