Output Files

XPF Files

Two algorithms may be applied to the data: Basic and Optimized.

>

Basic algorithm. The output XPF files contain all the information computed by the post-processing (navigation data, aiding sensor status, GPS post-processing, etc.).

>

Optimized algorithm. The output file contains only the navigation data resulting of the post-processing. Indeed, other information (such as aiding sensor status) is computed twice: once in the forward direction, once in the backward direction and cannot be displayed in the resulting merged data file.

To access this information, the user must set the “intermediate trajectory” field in the “Output panel” to “yes”. In that case, two intermediate files (corresponding to the forward and the backward processing) are generated and available in the “Variables” pane. Those files contain the same information as the one generated during a processing in Basic mode. Refer to XPF format specifications for more details.

 

Export Formats

Delph INS Subsea exports navigation data under several formats. Five formats are available:

>

Google Earth (KMZ) format: *.kmz data file that can be visualized into Google Earth

>

Geographic (SHP, KML …) format: standard *.shp or *.kml files that can be visualized in any regular GIS application

>

POSPac SBET (out) format

>

User defined format: described by the user by writing a template file

Custom formats can be added upon customer request.
