Use Precise Timing Architecture - used for data collected with an Applanix POSMV,
requires POSRAW packets
The same options for processing navigation from the file tree are available in the Mosaic
and Bathy wizards, except for the ability to monitor the progress with beamlines. For
users familiar with their data that know which navigation processing settings give the best
results, monitoring the effects of navigation processing with beamlines is not necessary.
2.3 External Navigation Processing
Perspective has the ability to export navigation and motion data for more rigorous
processing algorithms to be used. This is very useful for AUV surveys with navigation
drift over time. Some users have very advanced MatLab algorithms for recomputing AUV
navigation positions. To allow for these external processing algorithms, Perspective can
export navigation and motion data to an ASCII text file. This is accomplished by right-
clicking on either an individual file or on the root file tree node for each data type and
selecting
Export Navigation / Text
.
After the navigation and motion data has been externally processed, to import the data
back into the raw XTF files use the Navigation and Attitude Inserter shown below which is
launched from this Utility toolbar button
in Perspective.
