As a part of the EIVA project “260278 150030 BLOMS MARITIME S GAPS IMPL”
we have expanded ... format (See GAPS User Manual for details on the format).
NaviPac and IXSEA GAPS data format. As a part of the EIVA project “260278 150030 BLOMS MARITIME S GAPS IMPL” we have expanded the NaviPac input driver to support the IXSEA GAPS Standard exchange format (See GAPS User Manual for details on the format) $PTSAG,12,132810.234,71,03,2006,11,5650.55281,N,0900.01200,E,B,0123.4,1,0122.3*
Data Input: We have modified the ordinary “Remote dynamic objects x” to support the $PTSAG.
The driver will analyze the input automatic and select the format, as it now supports 1) NaviPac 2) Winfrog 3) NMEA 4) Expanded NaviPac 5) NaviPac SCS France 6) Apache $SFPOS 7) NaviPac Plus 8) IMCA Standard 9) Thales Tracks $PRPS,POSN
10) Century Subsea Spar The unit may read one or more inputs based on the TP code (between 1 and 128)
The objects will be treated as any other object in NaviPac.
The TUG1 in the above dump is positioned via GAPS. Please note that the following information is taken from the input Delta X The data latency (based on computer clock vs. time in telegram) Delta Y The Position Validity (0 – 15) Delta Z The Sensor Depth Height The Calculated Depth Please note that the calculation of the latency/age only will work if the two systems are synchronized to the same clock. The timestamp in the GAPS telegram are assumed to be UTC.
Installation The driver will be included in any version after 3.5. It can be added to 3.5 (or 3.4D patch 15) by including the following patches: \eiva\navipac\bin\kernelnt.exe \eiva\navipac\bin\dll\Inst421.dll
DATA Filtering If the GAPS unit output’s more than the one interesting telegram – eg. Also some of the other GAPS messages, then you must add a filter in the NaviPac system. This is done in NAVIPAC.INI (Open from Setup by pressing CTRL+ALT+SHFT+I). Find the line(s) for the GAPS interface: Instrument4.421=REM1, Instrument4.422=REM2, Instrument4.423=REM3, Instrument4.424=REM4, Instrument4.425=REM5,
